Tokyo electric two-wheelers

Just as carmakers develop electric cars, motorcycle manufacturers also see the writing on the wall, showing off a collection of electric bikes at the 2009 Tokyo Motor Show. The Tokyo Motor Show has always played host to a substantial display of motorcycles, and this year is no different–except that the highlights of the show all have a green angle. Honda, Yamaha, and Suzuki all brought concepts to the show that could spell the future of riding, and possibly a new way for future commuters to get to work.
2009 Yamaha XJ6

The Yamaha Diversion XJ6 is like the VMAX, a Ghost from the ’80s brought back to life by Yamaha in 2009. After years of the FZ6 acting as Yamaha’s entry level model into multi-cylinder motorcycles, the Yamaha XJ6 is back in Europe! Its aims are to be easier-to-ride-slow, less power, but with more torque in lower revs and, above all, to be even more affordable. After Honda proved there is a market for friendly middleweights with the CBF600, Yamaha has decided to do the same in the new Yamaha XJ6 series. The concept is pretty much identical to the original Diversion of the ’80s and ’90s, but in all-new trim. To achieve that, it needed to be less sharp than the R6-derived FZ6. The current FZ6 sports around 100 horsepower and everything from the engine to the chassis can be traced back to the pre-2006 R6 model.
The Yamaha XJ6 differs in several key areas, such as the detuned FZ6 600cc in-line four engine, new and simpler chassis, and different ergonomics. It’s all done to make the XJ6 as easy to get along with as possible. And easy it is to ride, indeed. When I first set off, the engine buzzes silently and the Yamaha XJ6 obediently pushes away from the traffic lights in the city center of Sydney. The engine specs are almost identical to Honda’s CBF600, which entails a 78 horsepower engine (@ 10,000) with 44 ft/lbs of torque at a relatively low 8,500 rpm. Although these small 600cc in-line fours like revs by nature, the Yamaha XJ6’s maximum torque figure is reached more than 1,500 rpm earlier than on the more highly strung Yamaha FZ6. This also means that the Yamaha XJ6 is easier to launch, and only a few revs are needed for decisive stop and go city riding. The Yamaha XJ6 also feels more powerful in the lower gears than the Honda.
BMW C1-E Electric Scooter

BMW Motorrad developed the C1-E study as a contribution to the European safety project eSUM. The BMW C1-E provides exemplary protection for its rider. This is ensured by the safety cell with the conspicuous roll-over bar which dynamically spans the rider seat in combination with the energy-absorbing impact element at the nose end. A further special point is that the C1-E rider wears a seat-belt. In the study this safety feature is highlighted by red belts and belt buckles. Visually the concept vehicle expresses brand typical sheer driving pleasure and clearly distinguishes itself from typical scooter looks. Its lines are dynamically stretched and flow horizontally with a low visual centre of gravity. The fairing with its windscreen, the luggage space behind the rider and the side stand for effortless parking ensure high suitability for everyday riding combined with a high degree of wind and weather protection.
The electric motor employed in the study has been designed for city use and is based on components by the company Vectrix. The motor obtains its power from a lithium-ion battery and thus possesses sufficient power for mastering most inner-city traffic riding with ease. Alternatively the vehicle could also be equipped with an efficient, low-emissions internal combustion engine. The safety features of the C1-E have been taken from the former BMW C1 and further enhanced. BMW’s avant-garde two-wheeler is regarded as a milestone in safety on two wheels. It is the only motorised single-track vehicle to be exempt from mandatory helmet wearing in almost all European countries. This BMW Motorrad study is likely to remain the only model of its kind. Series production is currently not planned. Nevertheless, findings from the project will find their way into other future developments in the field of single-track vehicles.
