APART from providing endless schoolboy sniggers the Wankel rotary engine is one of the greatest near-misses of 20th century engineering. It promised to revolutionise the bikes we rode and cars we drove, but despite decades of work never quite overcame the problems that prevented it from becoming a mainstream hit, wankel bike. But the basic idea of getting rid of wankel bike the reciprocating wv14 of a normal engine — the pistons, con-rods, valves — and replacing them with a design that does the same suck-squeeze-bang-blog sequence using purely rotating parts is, frankly, genius.

The world-class S engine produces a stunning amount of power from a small, compact and easy-to-integrate unit. All our engines feature patented SPARCS cooling technology to give you better performance and a longer-lasting engine. With a market-leading power to weight ratio and a compact design for easy integration, we'll help design and build the right solution for you. If you need an engine with unrivalled endurance, world-class power and a low total cost of ownership, the S is ideal for you. By combining our patented Compact SPARCS cooling system with a modern rotary engine you benefit from an engine which is reliable, efficient and long-lasting. And, because the S is compact and lightweight it's easier to integrate into your application. It will also give improved performance through being lighter and more aerodynamic.

Many of us know and are fans of rotary-engined cars like the Mazda RX-7 , but there are even cooler Wankel-engined motorcycles. The likes of Kawasaki , Suzuki , and Yamaha have also created wild rotary bikes. To know more about rotary motorcycles, we first have to get to know the rotary engine. Made by Dr. Felix Wankel in Germany in , it took some time for the eccentric rotary mill to jump from drawing board into production, be it for cars or motorcycles. In fact, the first production Wankel-powered cars and motorcycles only came around in the '70s. When it comes to the advantage of the Wankel engine as compared to the traditional counter-balancing piston format, it has uniform torque and less vibration. It also tends to have more power, is smaller, and weighs less. While all this makes it sound like a perfect fit for motorcycles, it is not as popular as the V-twin engines of today. For Wankel-engined motorcycles, there are serious drawbacks when it comes to engine seals and emissions, and these motors tend to have a limited lifespan. That said, there are plenty of Wankel-engined motorcycles around, and here are the coolest of them all.

Making a whopping horsepower from a cc twin-rotor Wankel engine and weighing less than pounds, this is a rotary-powered wankel bike that has a MotoGP-level power-to-weight ratio, wankel bike. This website is owned and published by Crash Media Group Limited. Van Veen.

The internal combustion engine has been with us since the s, but it has remained largely the same in all that time: pistons moving up and down in a cylinder, converting that movement to rotary movement by the use of a crankshaft. One brave and seemingly revolutionary development was the rotary engine , conceived by Felix Wankel in the s and offering advantages in simplicity of construction and power output. Here, we celebrate the motorcycles that dared to be different. It was also expensive, with Cycle World magazine summing up thus: "Less performance for more money takes this rotary out of the realm of practicality. It might not have made it into production - only two prototypes are believed to have been built - but it just shows how serious the Japanese manufacturers were considering the Wankel engine and how it was seen as one possible future for the motorcycle. It made its first appearance at the Tokyo Motor Show and was powered by a 66 horsepower, single rotor engine, fitted into the frame and running gear of the Yamaha TX, which at least gave it typical s Yamaha good looks.

APART from providing endless schoolboy sniggers the Wankel rotary engine is one of the greatest near-misses of 20th century engineering. It promised to revolutionise the bikes we rode and cars we drove, but despite decades of work never quite overcame the problems that prevented it from becoming a mainstream hit. But the basic idea of getting rid of all the reciprocating bits of a normal engine — the pistons, con-rods, valves — and replacing them with a design that does the same suck-squeeze-bang-blog sequence using purely rotating parts is, frankly, genius. We all know about Nortons and Suzuki RE5s, but there has been a host of other Wankel-engined bikes over the years, from prototypes to full production models. First on our list comes the earliest production Wankel motorcycle. The Hercules, which was marketed as a DKW in the UK, was sold for most of the s and as such was one of the most successful rotaries in terms of numbers built. But it nearly did, and this was it. Although pretty tidy-looking, only a couple of prototypes are believed to have been made. If you like the look, though, you can always try to find a conventionally-powered Yamaha TX — it used the same frame and suspension and looks virtually identical to the prototype RZ Norton spent most of the s fiddling with prototype rotary-powered bikes, but it took until before finally creating its first production Wankel, the Interpol II.

The revolutionary rotary engine designed by Dr. Felix Wankel, henceforth known as the Wankel engine, is a design of tremendous promise, and expensive vexation. It seemed the wonder motor of the future in the s, and many automobile manufacturers took a out a license on the design, from General Motors to Rolls Royce, as did many aircraft and. Felix Wankel born in Lahr, Germany had the vision for his remarkable rotary engine at the age of 17, began working on prototypes 5 years later, and gained his first patent for this remarkable engine in His work on the motor was slow in the following two decades as he developed rotary-valve applications for piston engines. By , working in conjunction with NSU, he had a fully functional rotary engine prototype, and immediately began licensing the engine, which had many theoretical advantages over a typical piston motor. First to take up this new design was aircraft engine builder Curtiss-Wright, who licensed the design on Oct.

Watch our world-class technology in action. When Yamaha looked for an alternative for its two-stroke motorcycle, they thought of the Wankel engine, and their prototype produced 66 horsepower with a cc engine. While all this makes it sound like a perfect fit for motorcycles, it is not as popular as the V-twin engines of today. Top 10 forced induction production bikes. It might not have made it into production - only two prototypes are believed to have been built - but it just shows how serious the Japanese manufacturers were considering the Wankel engine and how it was seen as one possible future for the motorcycle. It was an important motorcycle in Wankel-engine history. Unlike the lesser-powered Hercules, the Suzuki RE5 was also truly mass-produced with greater production numbers, although it too called it quits on the same within a couple of years. Go onto eBay right now and there will probably be one or two available. Configuration Air-cooled single-rotor Wankel engine Displacement cc 18 cu-in Horsepower hp Torque Made by Dr. How to perform a perfect U-turn during your motorcycle test.

And now for something completely different, I am pleased to offer this rare Hercules W Wankel rotary powered motorcycle. Who even knew that this bike existed? Certainly not me until recently.

How to perform a perfect U-turn during your motorcycle test. Norton spent most of the s fiddling with prototype rotary-powered bikes, but it took until before finally creating its first production Wankel, the Interpol II. It was also expensive, with Cycle World magazine summing up thus: "Less performance for more money takes this rotary out of the realm of practicality. Here's what every gearhead should know. Here, we celebrate the motorcycles that dared to be different. That said, there are plenty of Wankel-engined motorcycles around, and here are the coolest of them all. Top 10 copy bikes. When it comes to the advantage of the Wankel engine as compared to the traditional counter-balancing piston format, it has uniform torque and less vibration. Felix Wankel in Germany in , it took some time for the eccentric rotary mill to jump from drawing board into production, be it for cars or motorcycles. There was both oil- and water-cooling, with three separate oil reservoirs - sump, gearbox and a total loss tank whose contents were mixed with the petrol before entering the combustion chamber. Its final iteration today is a rotary-powered beast unlike another. Despite these advantages, Wankel-engined motorcycles have drawbacks such as engine seal and emission issues, as well as limited lifespan.
