Stroke Legacy

Welcome to @StrokeLegacy 🏍️ A place dedicated to the golden era of motorcycles — the scream, the revs, the pure emotion.

What if you combine the fuel tank and the motorcycle chassis into one structure? At 1980, Kawasaki engineer tried a new innovation. Inspired by aerospace technology, Kawasaki designed an aluminum monocoque frame that also served as a 32-liter fuel tank. The goal was to reduce the frontal area, lower the center of gravity, and drastically increase chassis rigidity. But it went wrong, 32 liters of fuel sloshing violently inside the frame during cornering made the handling unstable. It's called fuel slosh. And it was overly rigid. The frame was too stiff, causing the rider's hands to go numb from massive vibrations. In the hands of former 250 & 350cc world champion Kork Ballington, the bike was forced to fight the dominance of Yamaha and Suzuki. Its peak achievement came in the 1981 season when it finished 3rd at the Dutch TT (Assen) while also setting the fastest lap, and repeating a 3rd-place podium in Finland. After 2 years struggling, in 1982, Kawasaki revised the frame into a semi-monocoque and added a separate fuel tank. Ballington even successfully won the ACU British 500cc Championship. However, the development gap in GP 500cc was simply too wide. Kawasaki officially withdrew at the end of 1982. Though it failed, this aluminum chassis concept was later adapted by Kawasaki in the modern era via the Ninja ZX-12R (2000). #KawasakiKR500#KR500#KawasakiRacing#GP500#MotoGPLegend#TwoStroke

This Sunday is quiet without MotoGP & WSBK... But F1 is on! While waiting for the lights out at the Dutch GP, let's flashback to an F1 design that once made the paddock and fans shake their heads in disbelief. You know, not all extreme ideas ended up in Victory Just like The Ensign N179 (1979) - The "Cheese Crater" In 1979, British team Ensign, that was run by Mo Nunn unveiled the N179 car, their first proper ground-effect Formula 1 car. This car designed by Dave Baldwin alongside with Shahab Ahmed, ex John Surtees engineer, as a radical attempt to maximise downforce in the early ground-effect era. Ensign N179 was using aluminium monocoque chassis, with only two chassis ever built (MN09 raced, MN10 was a spare), powered by Ford-Cosworth DFV 3.0-litre V8 ( approx. 485 bhp. These power managed by Hewland 5-speed gearbox. The ideas? The idea was to free up the sidepods for better ground-effect tunnels. However, traditional radiators, mounted in the sidepods, had a problem. They disrupted airflow and limited how efficiently ground effect could work, se engineers were searching for ways to free up that critical space. Ensigns’s designer, Dave Baldwin and Shahab Ahmad, got an idea, instead of placing the radiators in the sidepods like everyone else, they moved them to the very front of the car. What made it even more interesting, not just one radiator, but three of them. So they put both water and oil radiators mounted right on the nose, stacked up to the top of the scuttle. In reality, it made the car looked terrible and produced almost no real ground effect. The handling were bad, too. People back then called it "Cheese Crater" Car. Not only that, this design failed to cooled the engine, ended overheated the engine. Uncontrollable heat then roasted the driver inside. 1979 season record showed how this ideas not ended well. After entered 11 Grands Prix , this car qualified for only 4 races, the other 7 races they even not qualified (DNQs). Their best and only one finish was 13th for Patrick Gaillard at the British GP. After the South African GP debut, the radiators were quickly moved to the sidepods. Unfortunately, the car still not competitive enough to get better result. It's pretty sad that ambitious and radical ideas looks good on paper, but they don't work well in reality #F1 #DutchGP #F1History #ExoticF1

Did you know there was a racing team that went bankrupt and had their bikes seized before the race? Sanvenero 500 : The Story of Italian Dream It all started in late 1980. Emilio Sanvenero was a wealthy Italian construction contractor with a simple obsession — he wanted his own name on a Grand Prix fairing. Not just as a sponsor, but as a proper manufacturer. So he started Sanvenero. The bike used a two-stroke square-four engine that was clearly inspired by the Suzuki RG500. It was built with expensive components, made around 120 horsepower, and weighed only 135 kg dry. The power delivery, though, was brutal and hard to control. In total, only three or four of these machines were ever built. Their moment of glory came in the most unlikely place: the 1982 French Grand Prix at Circuit de Nogaro. The track conditions were so bad that the big factory stars — Kenny Roberts, Barry Sheene, Freddie Spencer and others — refused to race. The grid was half empty. Taking advantage of the chaos, Swiss rider Michel Frutschi won the race. It was Sanvenero’s one and only 500cc victory, and the last time an Italian manufacturer won a premier-class Grand Prix until Cagiva came along ten years later (after MV Agusta’s last win in 1976). The good times didn’t last. The team had spent far more money than it could afford. By the German Grand Prix at Hockenheim in September 1982, they were declared bankrupt. The circuit even seized two of their bikes over unpaid debts. 📹Yt :@Classicbikeworld #Sanvenero500 #500ccGP #PrivateerRacing #GrandPrixHistory #TwoStrokeEra #MichelFrutschi #ClassicGP #MotorcycleRacing #WGP500 #ItalianRacing

|Just my two cents| I'm not against new tracks, good to see a new one though. But it would be lovely to watch them in old iconic Circuits. Spa-Francorchamps, Imola, or Suzuka maybe? But of course with appropriate/up to date safety standards. Old tracks had different vibes, different souls. And of course, wonderful & amazing layout ❤❤

How many pistons could you put into a Racebike? Meet the Moto Guzzi V8 (Otto Cilindri) — the only V8 engine in Grand Prix history Back in the 1950s, when most racing bikes were running one to four cylinders, the Italian manufacturer Moto Guzzi just stuffed EIGHT cylinders into a 500cc engine. To fit eight cylinders into 500cc, they made it so small, each one was only about 62.5cc. In 1957 this racebike could hit 286 km/h (about 178 mph) on the long straight at Spa-Francorchamps. Could you imagine, at that era it was running on thin tires, drum brakes, and a steel-tube frame. Terrifying, isn't? Powered with eight separate carburetors, and liquid cooled to avoid the heat, the engine made around 78-80hp at 12.000rpm. At 1950s era it was very impressive. People even said that the exhaust was screaming like a Formula 1 car. It was fast in a straight line but unfortunately never won a world title. Reliability issues and tricky handling led to a lot of DNFs. Still, it took a few pole positions (including one at the Belgian GP with Bill Lomas) and its best World Championship result was 4th place in the Senior TT at the Isle of Man with Dickie Dale. It also scored some wins in non-championship races in Italy. Moto Guzzi made an engine that was ahead of its time. But unfortunately tires, chassis, and brakes at that era just couldn’t keep up with the power. In the end, high mechanical complexity, tricky weight, and frequent component failures ultimately led Moto Guzzi to end the project in 1957. Do you like this type of content?

Not a V4, not an inline-four. This one’s a square-four. In the mid-1970s Suzuki dropped a new engine on the 500cc class and basically ended MV Agusta’s long reign. They called it the RG500 — a liquid-cooled, 498cc two-stroke square-four that became one of the most successful engines in Grand Prix history. The layout was clever: two parallel twins geared together, rotary disc valves, and a pair of counter-rotating crankshafts that kept the vibration surprisingly low. Factory race bikes were putting out somewhere between 110 and 124 horsepower while weighing only around 130–135 kg dry. Compact, light, and extremely fast. The results speak for themselves. Suzuki took seven consecutive manufacturers’ titles from 1976 to 1982. Four riders’ championships came with it too — Barry Sheene in ’76 and ’77, Marco Lucchinelli in 1981, and Franco Uncini in 1982. The first-ever 500cc Grand Prix win for Suzuki also happened on this engine, when Sheene took the 1975 Dutch TT at Assen. In 1976, the first full year the production version was available, RG500s filled 11 of the top 12 places in the final championship standings. For years the grid was just a sea of these things — privateers loved them because they could actually compete with the factory teams. The engine's advantages was obvious. Insane power-to-weight ratio, explosive top-end, excellent mechanical balance, and a compact size that made chassis design easier. Even privateers could go fast on them. The downside? The power delivery was vicious — almost nothing below 7–8,000 rpm, then the power just exploded. Run the mixture a bit lean and it would seize without warning. Tuning four carburetors plus the rotary valves was a nightmare for mechanics. It drank fuel and smoked like crazy. And eventually the inlet design was difficult, which is why Suzuki later switched to a V4. From the mid-70s right through early 1980s, Suzuki ruled two stroke era. #SuzukiRG500 #SquareFour #TwoStroke #GrandPrix #500cc #BarrySheene #ClassicRacing #MotoHistory #VintageGP #SuzukiRacing

WGP 500cc : ELF against The Titans After the ELF E, the radical French experiment tried to fight for highest level of Motorcycle racing, The World Grand Prix 500cc. Honda stay as a main engine supplier, but this time, with V3 2 stroke Honda NS500. ELF 2 (1984-85) André de Cortanze’s last creation. • Honda RS500 / NS500 3-cylinder 2-stroke (~120 hp) • Hub-centre steering • Engine as stressed member of the chassis • Push-pull / unique suspension geometry • Fuel tank in weird places Looked like it came from another planet. Handled like one too. Hard to ride, never really competitive. ELF 3 (1986) – The breakthrough Serge Rosset + Dan Trema take over the project. They were more pragmatic. • Works Honda NS500 triple (~137 hp) • Separate chassis for the first time • VGC front-end system • Dry weight ~119 kg Ron Haslam as their rider on board. Result: 9th in the 1986 World Championship (ahead of works Suzuki) and win at the Macau GP. This was ELF’s best season. The radical finally became raceable. ELF 4 (1987) Same DNA, now with Honda’s new NSR500 V4 (~140 hp). But engine arrived late, Haslam started the year on a standard NSR in ELF colours. He then use ELF 4 from 4-5 last races of the season. Not only cause of engine problem, but also developmental (chassis, brakes). Haslam finished 4th overall, most points he got from the standard bike. Podiums in Spain & Germany. ELF 5 (1988) – The final chapter Cast magnesium chassis, Nissin brakes, single-sided front, ~118 kg dry. Still the 1987-spec NSR500 V4. Haslam’s best results: a few 7ths and finished 11th in the championship. Project over due to some reason such as disappointing results, Retirement of the project’s main champion François Guiter, new management at Elf was no longer willing to continue pouring large amounts of money into an experimental racing program that wasn’t delivering championship results. And high development costs, but very limited sporting success. The project end in 1988. Which ELF is your favourite?

Could You Actually Race a Motorcycle With No Frame? Yes, Of course you could. Meet ELF X & ELF E : THE FRAMELESS RACE BIKE Part 1/ In 1978, ELF, a French oil company decided to make a break through. André de Cortanze (Renault F1 engineer) and ELF created the ELF-X. ✅No conventional frame. ✅Engine as the chassis. ✅Fuel tank under the motor. ✅Hub-center steering. ✅Parallel-arm front suspension. ✅Yamaha TZ750 2-stroke power. Specs (ELF-X): • Engine: Yamaha TZ750 – inline-4 2-stroke, 739–750cc • Power: ~120 hp @ 10,500 rpm • Weight: only 131 kg • Top speed: ±280 km/h It looked like.. something from the future. Debuted at Nogaro F750 with Michel Rougerie, but unfortunately retired early. The 2-stroke simply couldn’t handle being a fully stressed member. But it was a proof that the bike could worked out. The idea was too good to die, so Honda took over and supplied a RSC 1000 4-stroke engine. And in 1981 the ELF-E (for Endurance) was born. Specs (ELF-E): • Engine: Honda RSC 1000 – air-cooled inline-4 4-stroke, 999cc • Power: 125–130 hp @ ±10,000 rpm • Weight: 173–190 kg • Top speed: 280–287 km/h Same radical DNA, now refined: ✅ Frameless (engine = chassis) ✅Single-sided arms front & rear ✅Ultra-low centre of gravity ✅Quick-change wheels (pit stops in seconds) ✅One of the first carbon front discs Real advantages on track: → Extremely low CG = insane cornering stability → No fork dive under braking → Faster wheel changes in endurance races → Better aerodynamics + weight distribution close to 50/50 → Stiffer overall package than traditional framed bikes It was insanely fast, regularly on pole, and led races. But..its futuristic design came with distinct flaws: ❌​Lack of Front-End Feedback: riders feel it less 'natural'. ❌​Mechanical Complexity: Servicing, tuning, and repairing the intricate dual single-sided swingarms and steering linkages was a nightmare for mechanics. ❌​Extra Weight & Agility Issues: All the specialized linkage hardware added unnecessary complexity and weight ❌​High Development Costs Best result: 3rd at Mugello 1983. Then a special streamliner version (ELF-R) smashed 6 world speed records at Nardo in 1986. Honda later bought the patents and took it to VFR and RC30 (Pro-Arm single-sided swingarm) One wild idea and a decade of pure engineering madness.

What if a racing legend and an oil company built a Superbike together?” 🔥The Petronas FP1 : Malaysia's lost superbike dream🔥 The Petronas FP1 is an iconic Malaysian superbike with a unique history in international racing. Also known as the Foggy Petronas, this project was one of the most ambitious efforts ever by a non-traditional motorcycle manufacturer. Here are the key facts : It was originally a MotoGP project. Petronas initially developed a 990 cc (some sources say 989 cc) three-cylinder engine in collaboration with Sauber Petronas Engineering as a premier-class prototype called the Petronas GP1 for MotoGP. But midway through development, they decided to switch focus and enter the Superbike World Championship (WorldSBK) instead. To compete in WorldSBK, the three-cylinder engine capacity had to be reduced to 899.5 cc to comply with the then-current regulations limiting triples to a maximum of 900 cc. Petronas partnered with four-time WorldSBK champion Carl “Foggy” Fogarty to form the Foggy Petronas Racing team. Top riders such as Troy Corser, James Haydon, Chris Walker, Garry McCoy and others were signed to race the bike. Fogarty himself served as team principal (he did not race it, having already retired due to injury). Shortly afterward, the FIM changed the rules to allow all engine configurations up to 1,000 cc. This left the FP1 significantly underpowered compared to its rivals. FIM rules required Petronas to produce a certain number of road-legal versions. A total of 150 Petronas FP1 units were built worldwide: The first 75 units were assembled in the UK by MSX International in early 2003 to pass homologation inspection. The remaining 75 units were assembled in Malaysia by Modenas. Around 50 were reserved for the racing team, and the remaining 100 were offered to the public in signature colors: Panache Green (the distinctive Petronas green), Exotic Black, and Misty Grey. Many of these bikes remained rare and are now highly sought-after collector’s items. Despite the power disadvantage, the FP1 scored some impressive results: Podium (3rd place) for Chris Walker at Valencia in 2004. Podium (2nd place) for Troy Corser at Misano in 2004. Two pole positions by Troy Corser (Oschersleben and Magny-Cours in 2004). And...several front-row starts. Brief specifications (road version) Engine: Inline three-cylinder, 899.5 cc, liquid-cooled, DOHC Power: approximately 127–130 hp Dry weight: around 181 kg Öhlins suspension, Brembo brakes, lightweight wheelsThe design was aggressive and sleek, heavily influenced by Fogarty’s preference for a Ducati-like character rather than a bulky Japanese look. This ambitious project was officially shut down at the end of 2006 after development difficulties, reliability issues with the engine, and intensifying competition (especially once the major Japanese manufacturers returned at full strength). Fogarty later described the experience as “frustrating,” but he remained proud of what the team managed to build from scratch in such a short time. Although it never won a championship, the Petronas FP1 remains a powerful symbol of Malaysia’s big dream in the superbike world. A rare “lost superbike dream” that is still highly prized by collectors today. That’s the story of the Foggy Petronas FP1! Do you have any extra details to share?

What if you switch the positions of your fuel tank and expansion chambers? Honda NSR500 NV0A : One of the craziest engineering experiments in Grand Prix history. Honda flipped the whole layout upside down : A 32-liter fuel tank sat underneath the engine, while four expansion chambers were packed into the space where the tank normally goes. With a full tank the center of gravity dropped 30 mm lower. As the fuel burned off, it actually rose more than 30 mm, completely changing the handling from lap to lap. To make it work they needed dual vacuum fuel pumps (because the tank was below the carbs), a “revolver” system so they could swap main jets from outside the bodywork, and custom mini spark plugs that were only 49.6 mm long. Oh, and a counter-rotating crankshaft just to fight wheelies. The result? Insane heat cooking the rider and a weight distribution that kept shifting the whole race. As brilliant as it was, this upside-down monster only lasted one season before Honda went back to a conventional layout.A Brilliant idea, but unfortunately didn't work as expected #MotoGP #HondaNSR500 #MotorsportHistory

Although not the first to bring winglets to MotoGP, Aprilia consistently introduces new innovations such as ground effect technology, side fairings, and F-duct-like air ducts on their RS-GP. And now, they have this. It seems like their engineers never run out of new ideas to try.. Brilliant, isn't it?

THE ONLY DEAD HEAT IN 500cc HISTORY Legendary moment captured on this foto. A "dead heat" in racing refers to a situation where two or more competitors cross the finish line at the exact same time, making it impossible to determine a single winner. The only one dead heat in WGP 500 history happened in 28 June 1975 at 'The Cathedral' Assen Circuit in front of 140,000 screaming fans. Just 3 months after surviving a 175 mph crash at Daytona that broke his leg, arm, collarbone, ribs & vertebrae, Barry Sheene was involved in a battle for first place against Giacomo Agostini (Yamaha) They crossed the line with the EXACT same time: 48'01.000. Back then, timing only measured to tenths of a second. Photo finish gave it to Sheene by half a bike length. It was first-ever 500cc GP win for Sheene. First premier-class win for the legendary Suzuki RG500. Sheene later said:“I knew the Suzuki was much quicker. I waited for the finishing straight.” Sheene later win the title the next two years. What’s the most epic tight finish in racing you’ve remember? #StrokeLegacy #BarrySheene #Agostini #Assen #DutchTT #ClassicMotoGP #TwoStrokeForever #RG500 #Suzuki

John Kocinski & the Cagiva 500 – The Beautiful Underdog That Almost Beat the Japanese Giants In the early 1990s, while Honda, Yamaha and Suzuki ruled the 500cc class with factory budgets and endless development, a small Italian team from Varese dared to fight. Cagiva. Led by the Castiglioni brothers and managed by none other than Giacomo Agostini, the red machine was pure passion wrapped in carbon and aluminium. The bike looked sleek, aggressive, and impossibly beautiful. Then came John Kocinski. The fiery American 1990 250cc World Champion joined mid-1993 after a split with Suzuki. Demanding and insanely talented, “Little John” was exactly what the underdog needed. His third race on the Cagiva C593? Victory at Laguna Seca 1993 — Cagiva’s first dry-weather Grand Prix win. In front of his home crowd. Against Doohan, Schwantz and the Japanese armada. In 1994,the evolved C594 was even better. Kocinski won the season opener in Australia at Eastern Creek, led the championship early, and scored seven podiums. He finished the year 3rd overall with 172 points — just two points behind Luca Cadalora and light years ahead of what anyone expected from a privateer Italian project. The technical heart of the beast: • Liquid-cooled 80° V4 two-stroke, 498 cc • Bore × stroke: 56.0 × 50.6 mm • Twin counter-rotating crankshafts + big-bang firing order • Power: ~185 hp @ 12,500–12,600 rpm • Torque: ~103 Nm @ 12,100 rpm • Reed-valve induction with pressurized airbox • Electronically controlled cylindrical power valves • 36 mm twin-choke Mikuni flat-slide carburetors • Early electronic quickshifter and experimental traction control • Dry weight around 128–130 kg The Cagiva wasn’t the most powerful bike on the grid, but its chassis (aluminium twin-spar, later carbon-composite) and razor-sharp agility made it a pure rider’s machine. Kocinski thrived on its precise steering and explosive mid-range. Kocinski himself later said: “It is one of my greatest accomplishments to win on a machine that no one else other than Eddie Lawson had won on. It was heartbreaking when Cagiva could not continue in 1995, because we were so close to having a machine that could win a World Championship.” Sadly, money ran out. The Castiglionis turned their focus to resurrecting MV Agusta, and the red 500 disappeared forever. For one brief, glorious moment, an Italian underdog with an American genius on board made the Japanese factories look over their shoulders. Pure passion. Pure two-stroke chaos. Who else thinks the Cagiva 500 deserved at least one more season? Drop a ❤️ if this story hits you the same way. More forgotten legends coming.

The Man Behind the Legend: Graziano Rossi’s Grand Prix Story Graziano Rossi was born on 14 March 1954 in Pesaro, Italy. Before becoming widely known as the father of MotoGP legend Valentino Rossi, he was a talented Grand Prix rider in the late 1970s and early 1980s. He made his World Championship debut in 1977 with Suzuki in the 500cc class. His best season came in 1979, when he raced for Morbidelli in the 250cc class. That year, Graziano scored three Grand Prix victories — in Yugoslavia, the Netherlands (Assen), and Sweden — along with a total of five podium finishes. He finished 3rd in the World Championship behind his main rivals, Kork Ballington and Gregg Hansford. In the 500cc class, Graziano competed against some of the biggest names of the era. He was teammates with Marco Lucchinelli at the Suzuki team run by Roberto Gallina in 1980, and raced against strong riders such as Franco Uncini, Virginio Ferrari, as well as international stars like Kenny Roberts and Barry Sheene. In the 1980 season, he finished 5th in the World Championship with two podium results. Overall, Graziano recorded 3 wins, 7 podiums, 1 pole position, and 114 points in Grand Prix racing. He competed for Suzuki, Morbidelli, and Yamaha (Giacomo Agostini’s team) before retiring in 1982 after a serious crash at Imola that nearly cost him his life. After retiring from motorcycle racing, Graziano tried his hand at car racing, including touring cars and rallying. However, his greatest legacy came off the track: he played a key role in guiding Valentino from a young age. The legendary racing number 46, which Valentino made famous, originally came from the number Graziano often used during his career. Graziano Rossi may never have won a world title, but he remains an important part of MotoGP history — both as a rider who competed against the greats of his era, and as the father who helped shape one of the greatest legends the sport has ever seen. #GrazianoRossi #ValentinoRossi #MotoGP #GPHistory #MotorcycleHistory

What happens when F1 engineers build a MotoGP engine? In 2006, Formula 1 engine specialists Ilmor shocked the paddock by bringing an 800cc V4 to MotoGP — the first 800cc engine that join 990cc race. Designed by Mario Illien, the X3 featured several advanced technologies ahead of most of its rivals. It used pneumatic valves (instead of conventional steel springs), gear-driven cams, and electronics derived from Formula 1. Unlike the established manufacturers who had to downsize their existing 990cc engines, Ilmor designed a pure 800cc unit from the ground up, allowing better optimization for the new regulations. The bike became the first 800cc machine to score World Championship points, finishing 15th twice with Garry McCoy against the more powerful 990cc bikes. The project lasted just three races. After a single outing in 2007, funding ran out and Ilmor withdrew. A brilliant engine with serious technical potential… One of MotoGP’s most fascinating “what if” stories 📹 YT : @Speedbox

From Boat Engine to World Championship Contender : The Story of Kim Newcombe & the König 500 One of the most unique motorcycle in the history of the 500cc World Championship was an boat engine made by company in Berlin called König Motorenbau. In the late 1960s, Dieter König decided to take one of his powerful flat-four two-stroke boat engines and turn it into a Grand Prix racer. A young New Zealander named Kim Newcombe arrived at the factory in 1968 looking for work. What started as a temporary job became one of the greatest underdog stories in Grand Prix history. Kim Newcombe (born 2 January 1944 in Nelson, New Zealand) was already an accomplished motocross and speedway rider. He had also worked as a marine engine mechanic in Melbourne, so he knew König engines well. He took over the project completely — designing the frame, developing the engine, maintaining the bike, and eventually becoming its primary rider. The König 500 featured a water-cooled flat-four two-stroke engine of around 492–494 cc, mounted longitudinally with rotary disc valve induction. Power grew from an initial 68 hp to 80–85 hp at around 10,000 rpm, while the bike weighed only about 115–125 kg. It used a Norton six-speed gearbox. Because of its marine origins, the exhaust note was a distinctive high-pitched howl, quite different from the Japanese and Italian machines of the era. The custom water-cooling system with a self-built radiator was also quite radical for a 500cc Grand Prix bike in the early 1970s. In 1972, during his first World Championship season, Newcombe finished third at both the West German and East German Grands Prix — an extraordinary result for a true privateer. Their team was tiny and completely self-run. They nicknamed themselves “Deadly Sins” because they operated with almost no resources. Kim’s wife Janeen played a crucial role behind the scenes, handling logistics, helping with mechanical work in the paddock, and documenting their entire European adventure. The 1973 season became their breakthrough year. Newcombe won the Yugoslavian Grand Prix — the only Grand Prix victory for the König. At one point he even led the 500cc World Championship standings ahead of Phil Read and Giacomo Agostini. On many tracks the boat-engined machine was faster in a straight line than the mighty factory MV Agustas. Tragedy struck on 11 August 1973 at Silverstone during a non-championship Formula 750 race. Riding an overbored 680 cc version and leading comfortably, Newcombe suffered brake failure after the long Hanger Straight. He lost control at Stowe Corner and crashed into an unprotected concrete wall. He never regained consciousness and died three days later, on 14 August 1973, at the age of 29. Posthumously, Kim Newcombe was classified second in the 1973 500cc World Championship, ahead of Agostini, with one win and six podium finishes from eleven starts. After his death, Dieter König withdrew from solo Grand Prix racing. However, König engines went on to dominate the sidecar class, winning the World Championship in 1975 and 1976. The remarkable story of Kim Newcombe, his relationship with Janeen, their struggles as privateers, and the tragic end at Silverstone was later captured in the award-winning 2007 documentary Love, Speed and Loss by New Zealand director Helen Whitney. The König 500 remains one of the most extraordinary machines ever to compete in Grand Prix racing — a boat engine that nearly toppled the greatest manufacturer of its era, ridden by a man who built, developed, and raced it himself. #König500 #KimNewcombe #GrandPrix #MotorcycleHistory #ClassicGP #500cc #UnderdogStory #MotoHistory #VintageRacing #TwoStroke #GPRacing

#OnThisDay Niki Lauda’s Nürburgring Crash: The Greatest Comeback in F1 History On 1 August 1976, during the German Grand Prix at the deadly Nürburgring Nordschleife, reigning world champion Niki Lauda suffered one of the most horrific crashes in Formula 1 history. The race started in mixed conditions. Most drivers, including Lauda, began on wet tyres and pitted at the end of lap 1 to switch to slicks. Lauda was pushing hard to recover positions on his second lap. Approaching the fast left-hand kink before Bergwerk, Lauda’s Ferrari 312T2 suddenly snapped right at around 190-220 km/h. The car hit the embankment, bounced back onto the track, and the fuel tank ruptured — turning into a fireball. Lauda’s helmet was torn off in the impact. He was trapped in the burning cockpit, fully exposed to the flames. Fellow drivers Guy Edwards, Brett Lunger, Harald Ertl, and Arturo Merzario stopped to help. They pulled him from the inferno after he had been sitting in temperatures of several hundred degrees for roughly 45-55 seconds. Injuries were catastrophic: • Third-degree burns to face, head and hands • Partial loss of his right ear • Broken cheekbone and ribs • Severe lung damage from toxic fumes He was given the last rites in hospital. Doctors fought to keep him alive. Lauda later said the real battle was “fighting with your brain” to stay conscious and refuse to die. Against all odds, he survived. Just 42 days later, on 12 September 1976, a scarred but determined Lauda was back in the Ferrari at Monza. He finished 4th. One of the greatest comebacks in sports history. Lauda lost the 1976 title to James Hunt by a single point… but won the championship again in 1977 (and a third title in 1984). The crash also helped push Formula 1 toward much stricter safety standards. Niki Lauda never hid his scars. He wore them as a badge of survival and sheer willpower. A true legend. RIP Niki (1949–2019). #NikiLauda #Nürburgring #F1 #Formula1 #GermanGP #Comeback #MotorsportHistory #Lauda #1976 #GreatestComeback

Fun Fact: Bridgestone once built motorcycles — and their two-strokes were ahead of their time. Yes, the tire giant Bridgestone actually manufactured motorcycles from 1952 to 1970. Their air-cooled two-strokes featured rotary disc valves, automatic oil injection, and high-quality engineering that often made them more expensive (and better finished) than rival Hondas or Yamahas of the same era. Standout models included the 175 Dual Twin — famous for its unique “Sport-Shift” gearbox that could switch between 4-speed rotary and 5-speed modes on the fly — and the powerful 350 GTR, one of the quickest 350cc production bikes of the late 1960s. They never mass-produced a street 125, but a highly modified Bridgestone 125 racer built by Dutch privateer Jos Schurgers (using leftover Dual Twin cases) won the 1973 Belgian Grand Prix, beating legend Ángel Nieto, and finished 3rd in the 125cc World Championship. Top speed? Around 220 km/h with ~35 hp. Bridgestone quit making bikes in 1970 not because they failed, but because their tire business was booming — and they didn’t want to compete with the manufacturers who were buying their tires. Short-lived, high-tech, pure two-stroke engineering. A true forgotten piece of Japanese motorcycle history. Who else still has a soft spot for these rare Bridgestones? #TwoStroke #MotorcycleHistory #ClassicMotorcycles #Bridgestone #StrokeLegacy

#FlashbackFriday Jorge Lorenzo’s Cornering Style at Yamaha (The “Hammer & Butter” Style – Broken Down by Phases) Jorge Lorenzo’s peak years at Yamaha (2008–2016) produced one of the purest and most beautiful cornering styles in modern MotoGP history. He called it “Martillo y Mantequilla” — Hammer & Butter. The philosophy was simple: Be as smooth as butter most of the time… but strike like a hammer when it mattered. Here’s how that style worked across the three phases of a corner. Phase 1: Corner Entry (Braking + Turn-in) This was pure Butter. Lorenzo was rarely the latest braker. He released the brakes earlier than most and tipped the bike in very progressively. No sudden movements, no aggression. Body position started dropping early (head and shoulders low). Goal: carry as much speed as possible into the next phase while keeping the bike stable. Phase 2: Mid-Corner This was Lorenzo’s greatest strength — the heart of his style. Extremely high corner speed. Very high and stable lean angles (he held the record at 64° in 2013). Elbow regularly on the ground, but everything looked calm and controlled. Light maintenance throttle to keep the bike settled. Wide, flowing lines instead of squaring the corner off. While others were still recovering from entry, Lorenzo was already carrying massive momentum. Phase 3: Corner Exit Here the Hammer started to appear. He opened the throttle very progressively at first. Because he already had high mid-corner speed, he didn’t need to be overly aggressive early in the exit. Once the bike began to stand up, he would then “hit” the throttle hard. The Yamaha M1’s strong traction helped him drive out cleanly with minimal wheelspin. Summary of Lorenzo’s Yamaha style by phase: Entry** → Smooth, controlled, speed-focused (Butter) Mid-corner** → Maximum corner speed & lean (Pure Butter) Exit** → Progressive then aggressive drive (Butter → Hammer) This combination made him devastating on flowing circuits. When Lorenzo was “on song,” his rhythm was almost impossible to break. Lap after lap, the times stayed within a tenth. It wasn’t the most spectacular style… but it was one of the most effective and elegant the sport has ever seen. Smooth as butter. Hard as a hammer. That’s classic Yamaha-era Jorge Lorenzo.

Great body position, how he leans toward corners, and how smoothly he changes body position at chicanes. Superb for his age!
