Meet Kawasaki’s new litre bike, ahead of its official launch thanks to a number of low-resolution images leaked onto the web by Italian website, Motobox.
Kawa’s 2011 ZX-10R leaked
Powered by a new 147kW powertrain (upped to a very chunky 154kW with RAM Air), and weighing in at 198kg, the most powerful ZX-10R yet sports a number of improvements to bring it on par with its competition.
According to a leaked document published by our American friends at Hell for Leather, the new engine features a completely revised crank/transmission shaft layout. This new layout contributes to a higher centre of gravity and better centralised mass form more nimble handling.
Larger intake valves (increased by 1mm to 31mm), new lightweight pistons with thinner oil rings, lighter but harder camshafts (now manufactured from chromoly rather than cast iron) and a single-shaft secondary balancer which reduces engine vibration, further improves the powertrain.
The 2011 Nina is also treated to a near-horizontal rear shock which positions the shock arm and linkage above the swingarm. According to Kawasaki this new arrangement increases road holding, ensures a smoother ride and gives better feedback.
A Big Piston Front fork, like the one used on the 2010 ZX-6R, is one of the most notable changes to the new ZX-10R.
Compared to a cartridge-type fork of the same size, the BPF features a main piston almost twice the size. Because of the larger surface the dampening pressure can be reduced without lowering the damping force, which in turn means smoother movement and greater control.
As expected, the new litre Ninja will receive Kawasaki’s S-KTRC (Sport-Kawasaki Traction Control). Unlike some traction control systems, which aim to inspire riders with confidence, the ZX-10R’s system uses its MotoGP racing racing technology to allow riding at the edge of traction.
The 2011 Kawasaki ZX-10R will be officially launched at the Intermot motorcycle show in Cologne.
