October 28, 2005 UPDATED IMAGES For the last 125 years, motorcycles have been made up of two wheels and a motor, and they have all been arranged as a wheel, a motor and another wheel – in that order – all of them. But the freedom afforded to designers by the in-wheel electric motors which technology has recently spawned will make for some interesting changes over the coming years and Yamaha is the first of the motorcycle manufacturers to seriously look at alternatives available in the next generation of motorcycles. The Deinonychus prototype takes full advantage of the greater chassis design freedom afforded by an in-wheel motor, and offers a completely new type of two-wheel-drive (2WD) EV (electric vehicle) with "Stretch & Shrink" functions in the vertical and horizontal directions. Yamaha’s exhibition at the Tokyo Motor Show features a number of futuristic commuter vehicles other than the Deinonychus including a fuel cell prototype, a hybrid prototype and a production electric scooter. For the record, a Deinonychus is a lightly built, fast-moving, agile, bipedal, killer dinosaur. This article includes a full rundown of Yamaha's other electric, methanol and hybrid scooters shown at Tokyo
The all-wheel drive motorcycle seems certain to become more widespread over coming years as yet another major motorcycle manufacturer has disclosed its activities in the area. Austrian motorcycle powerhouse KTM is working in conjunction with Swedish Company Ohlins in the development of a mechanical/hydraulic system for driving the front wheel. A 2WD equipped KTM 525 EXC has been race tested in Europe recently by KTM Sport Director and former Factory Rider Kurt Nicoll.
Austrian motorcycle powerhouse KTM has been around longer than Honda, Yamaha and Ducati, but only really became a recognised international marque in the last 25 years, thanks to its fast and reliable off-road motorcycles.
Sunday November 16, 2003 In one of the most significant moves in motorcycle history, Yamaha has announced that it will release a two-wheel drive motorcycle early in 2004.Though it is not the first two-wheel drive motorcycle in history, the new machine will be a landmark model as it seems certain to be the first of many - testing over the last five years has indicated enormous benefits in terms of safety, traction and (probably the one that counts most) outright cornering speed in slippery, sandy or muddy conditions.
