Kawasaki Ninja ZX-10R

The Kawasaki Ninja ZX-10R is a Kawasaki sport bike, the successor to the ZX-9R. The crankshaft axis, input shaft and output shaft of the Ninja ZX-10R engine are positioned in a triangular layout to reduce engine length, while the high-speed generator is placed behind the cylinder bank to reduce engine width. The DOHC are machined from chromoly steel built for strength, four valves per cylinder improve high-rpm breathing, and the forged, lightweight pistons offer high heat resistance to further enhance the bike's power-to-weight ratio.

In addition to liquid cooling, the ZX-10R engine has an oil cooler adjacent to the oil filter to reduce oil temperatures. The 2004 model was the debut of the Ninja ZX-10R. The engine remained largely unchanged.

The 2006 ZX1000D6F model carried over to the 2007 model year, with only color scheme changes. Kawasaki moved away from the twin underseat exhausts of the 2006–2007 model to a more conventional single side exhaust. The 2009 model received only slight changes from the 2008 model.

The 2010 model received slight changes from the 2009 model, including, upgraded Öhlins steering damper, upgraded transmission, and revised bodywork. The 2011 ZX-10R underwent major overhaul both mechanically and visually. Most notably, Kawasaki introduced their Sport Kawasaki Traction Control system as standard. In 2013 the models went under another small revision where the colors offered changed again and the front dampener was replaced with an Ohlins electronic front steering dampener.
