Kawasaki Ninja ZX-10R
The Ninja ZX-10R is a Kawasaki Sport bike, and the follow-up to the ZX-9R . It was originally released in 2004 with minor revisions in 2005. It combines an ultra-narrow chassis, low weight, and radial brakes. In 2004 and 2005 the ZX-10R won Best Superbike from Cycle World magazine and the prestigious internationalMasterbike competition.
According to the Insurance Institute of Highway Safety, The ZX-10R has the highest theft and damage loss claim rate of any registered motorcycle.
Engine
Kawasaki engineers utilized a "stack" design for a liquid-cooled, 998 cc inline four-cylinder engine. The crank 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 
Cooling system
In addition to liquid cooling, the ZX-10R engine features an oil cooler adjacent to the oil filter to reduce oil temperatures. "Slosh" analysis was also used to design the internal structure of the oil pan, thereby reducing windage losses and helping to maintain low oil temperatures.
Clutch
A multi-plate wet clutch with a back Torque limiter transfers power to a six-speed, 
Wheels
A new six spoke wheel design is claimed to be almost as light as special purpose race wheels. Since the 2006 model the sidewall profile of the rear tire has been increased from 190/50/ZR17 to 190/55/ZR17.
2006 model
Among other changes, the 2006 model featured twin underseat exhausts which contributed to a 5 kg (11 lb) increase in dry weight. The engine remained largely unchanged.
The 2006 ZX1000D6F model carried over to the 2007 model year, with only color scheme changes. The most noticeable difference between 2006 and 2007, is that the heat-shields on the exhaust pipes are black on the '07 ZX10R, and '06 came with silver ones.
2008 model
The ZX-10R was all new for its launch for the 2008 model year. There was a dramatic change in appearance with the bike featuring a much more angular front end. Kawasaki moved away from the twin-underseat exhausts of the '06-'07 model to a more conventional single side exhaust. The compression ratio of the engine was raised so that the engine now produces 188 PS (138 kW; 185 hp) @ 12,500 rpm and 200 PS (147 kW; 197 hp) @ 12,500 rpm with ram air.
2009 Model
Received only slight changes from the 2008 model.
2010 Model
Received slight changes from the 2009 model, including: upgraded Öhlins steering damper, upgraded transmission, and revised bodywork.
