The Kawasaki Ninja ZX-6R is a Kawasaki 600cc class sportsbike . It was introduced in 1995, and has been constantly updated throughout the years in response to new products from Honda,Suzuki,and Yamaha. The ZX series is what was known as the Ninja line of Kawasaki motorcycles
in the 1980s and still carries the name today.
When Kawasaki introduced the ZX-6R in 1995, it was the first middleweight sport bike with an aluminum frame since the 1992 GSXR600. It had a dry weight of 401.2 lb (182.0
kg), wet weight of 454 lb (206 kg), and was capable of accelerating 0 to 60 mph (0 to 97 km/h) in only 3.6 seconds.
In 2005, Kawasaki again revamped the ZX-6R. Engine speed increased again by 1,000 rpm resulting in 113 hp (84 kW) at 12250 rpm.In 2005, Kawasaki again revamped the ZX-6R. Engine speed increased again by 1,000 rpm resulting in 113 hp (84 kW) at 12250 rpm. The frame and swingarm were updated, but the main changes from its predecessor lay in the design. The aluminum frame was now painted flat black, fairings were more round, and integrated turn signals were used (euro model). The exhaust was now centrally under the seat (a configuration commonly referred to as an undertail exhaust). Most of these changes were mirrored in the 599 cc ZX-6RR. For the second year in a row, the ZX-6RR again won the Supersport category award for Masterbike 2005 and placed third overall. The bike carried over to the 2006 model year with minor suspension changes and new color schemes.
After four years of offering their 636 cc ZX-6R for street use and an entirely separate 599 cc ZX-6RR for displacement-restricted racing classes, Kawasaki offered only one ZX-6R for 2007, and it displaced 599 cc. Previous years of the ZX-6R's engines were all built from the same basic design, but the all-new engine for 2007 was redesigned from the crankcase up. In following with what their competitors had already been doing, Kawasaki's new engine featured a stacked gear arrangement in which the crankshaft, primary drive and countershaft are placed in a triangular format for a shorter, more compact powerplant. Now about 40 mm smaller in both length and width and it is said to yield greater cornering clearance.
Third GenerationEditFor 2009, Kawasaki dramatically changed the appearance of the ZX-6R to match the more angular look of the ZX-10R. The frame was lightened albeit with the same basic construction resulting in 191 kg (420 lb) wet as opposed to 205 kg (450 lb) in 2008.Kawasaki claims the new ZX-6R is 10 kg lighter than the previous model. The greatest changes for 2009 were the redesign of the exhaust, now carried low and not requiring the thick under-seat construction of 2008 and especially the introduction of the BPF (Big Piston Fork) suspension from SHOWA for a more progressive brake-dive.
The 2010 ZX-6R is changing once more with an improved engine and slipper clutch. The exhaust pre-chamber has more space and also limits exhaust noise giving the rider a smoother ride. New double bore intake funnels features two available heights which gives performance upgrades in both high and low engine speeds. The front seat is now lower.
