IOMTT: Kawasaki-Zytek ZX10ev Breaks Cover with 134hp, Six-Speed Gearbox, & Kawasaki Motors UK

By 5 Comments

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.”

Did Kawasaki Just Enter TT Zero Without Anyone Noticing?

By 20 Comments

The Isle of Man TT sent out an interesting press release yesterday, where it cited the largest competitor entry list in the TT Zero’s race history (lawyer’s crafty word choice note: this does not include when in 2009 the race was run under the TTXGP banner and 23 competitors allegedly entered). With 18 competitors signed up for the single-lap electric motorcycle race around the Mountain Course, we can surely expect the field to dwindle, as virtually none of the electric series have been able translate large entry lists into large starting grids, sans maybe the FIM e-Power race at Laguna Seca, which TTXGP is now piggy-backing off of as well.

Announcing the return of MotoCzysz and its two-rider team of Mark Miller and Michael Rutter, the Isle of Man TT also gave a nod to the Mugen entry, which is widely believed to be a front for Honda’s own electric motorcycle racing program. Having 17-time TT race winner, and long-time factory Honda rider John McGuinness at the helm of the Mugen Shinden has only added further credence to the rumor. However getting only one sentence in the press release was perhaps the most intriguing entry to the list of competitors: Bournemouth Kawasaki/Zytek Automotive, which will race the team’s Kawasaki-Zytek ZX10ev race bike.
