Kawasaki Showcases Prototype Hybrid Motorcycle

Kawasaki has been filing patents and revealing hybrid technology in several intellectual property filings over the past year or so. Now, the first prototype of a hybrid motorcycle has been revealed at a presentation in Japan. The hybrid models could range from high-performance machines, similar to the current H2 models, or touring bikes, which would be better suited to absorb the additional weight of a dual-drive system. Either way, Kawasaki seems to be hard at work, on both electric and hybrid systems, and going by the prototype shown, it won't be long before a full hybrid model is introduced.

The prototype also incorporates an automated gearshift system to smoothly transition between the power modes.

According to Kawasaki, the hybrid system can work using regenerative systems to top up the hybrid battery, a relatively small 48V pack located under the seat. Also doing duty is a small parallel-twin engine, bolted on to a new tubular steel frame, with a large electric motor mounted above the transmission. In city mode, the bike turns to pure electric power, switching off and disengaging the combustion engine. This mode will be useful when some cities introduce zero emissions zones in the future.

Once outside the city limits, the hybrid system will operate both the electric motor and the combustion engine to give a level of performance that's higher than what either can achieve on its own. The prototype machine also comes with automated gearshift, which Kawasaki has filed for patents earlier this year. The system uses an automated clutch and a servo-operated shifter, allowing push button changes.
