Kawasaki Z900

The Kawasaki Z900 replaces the outgoing Z800 and uses an engine based on the Z1000. With this bike Kawasaki hopes to better compete with Yamaha’s MT-09 and Triumphs Street Triple.

The middleweight Z weighs around 22kg less than the 800 and is around 11kg lighter than the Z1000, thanks to Trellis steel frame and aluminium swingarm.


The engine is based on the Z1000 engine. Not only externally but internally aswell. With 56mm the 900’s stroke dimensions for example, are exactly the same as on the Z1000. Only the bore is smaller on the 900.

A slipper clutch is fitted, for lighter lever feel and reduced wheel hop while downshifts. The Gear ratios have also been changed. The first five gear ratios are now shorter to improve acceleration in the midrange, so the last gear is actually intended as an overdrive 6th gear.

Brakes and suspension

Stopping power is ensured by 4-piston Nissin calipers and 300mm discs up front. In the rear there is a 250mm disc.
The rear suspension is basically the same as the Z800 and the previous Z1000, while Kawasaki fitted a 41 mm inverted fork in the front.


On this Z-model you won’t find any electronic aids like traction control, or wheelie control, except for ABS which is optional on the Z900.
