With Honda’s electric motorcycle racing effort thinly disguised as the Mugen Shinden and getting a tremendous amount of attention, the motorcycle racing press missed the very subtle joint-entry by Zytek Automotive and Bournemouth Kawasaki Racing into the 2012 TT Zero. Already incorporating one of the most advanced technology groups in electric and hybrid automotive technology, as well as one of the top Isle of Man TT racing teams, the Kawasaki-Zytek ZX10ev race bike also benefits from another important element: the backing of Kawasaki Motors UK.
Using one of Zytek’s 100 kW (134 hp) permanent magnet oil-cooled KERS motors for its power plant, the Kawasaki-Zytek ZX10ev has the added benefit of a six-speed gearbox, which like the bike’s chassis, is a recycled component from the Kawasaki Ninja ZX-10R donor bike the electric racer is built from. Using the firm’s automotive racing experience to its benefit, Zytek’s motor design has previously been used on the company’s Hybrid Le-Mans 24 hour race-winning car, and uses technology similar to Zytek KERS system used in the 2009 Formula 1 Championship.
Powering the motor will be four 15Ah LiFeP04 cylindrical cell battery packs, which have been located in the ZX-10R’s fuel tank, airbox, radiator, & exhaust for a total of 11.8 kWh in energy storage. “The shape of the Ninja ZX-10R frame is designed to curve around a conventional engine, and does not lend itself naturally to the fitment of a battery,” said Zytek Project Manager Des Hill. “We have ended up filling the area normally use by the tank, air-box, radiator and exhaust with four sculpted packs. In total we have 240 power cells carefully distributed around the bike.”
