Among other changes. the 2006 model had twin underseat exhausts which contributed to a five kg (eleven pound) 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 2007 ZX10R. and 2006 came with silver ones. 2006 Kawasaki Ninja ZX-10R Year2006 ManufacturerKawasaki Model NameNinja Trim NameZX-10R Generic Type (Primary)Sport Revision StatusCarryover EngineStandard Engine TypeHorizontal In-line Cylinders4 Engine Stroke4-Stroke CoolingLiquid Valves Per Cylinder4 Valve ConfigurationDOHC Bore (mm)76 Stroke (mm)55 Displacement (cc)998 Compression Ratio12.7:1 StarterElectric CarburetionStandard Carburetion BrandMikuni Carburetion TypeFuel Injected TransmissionStandard Transmiss...
