With very similar looks and features like the 1994 introduced ZX-9R, including the ram-air intake that had been developed by Kawasaki since the 1990 ZX-11 (ZZ-R1100). The first ZX-6R 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 (…

With the Launch of the G series. The G series saw no increase in displacement but power went from 100 BHP to 108 BHP thanks to the newly designed airbox.

The first J series replaced the G, increasing power to 112 BHP by increasing the compression ratio from 11.8:1 to 12.8:1.

There were a number of changes to the ZX-6R, or ZX636 as it is often referred. The engine was fuel injected and engine speed was raised around 500 RPM which resulted in a slight gain in power.

Kawasaki again revamped the ZX-6R. Engine speed increased again by 1,000 RPM resulting in 131 hp (98 kW) at 12,250 RPM.

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 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.

Kawasaki dramatically changed the appearance of the ZX-6R to match the more angular look of the ZX-10R. Kawasaki claims the new ZX-6R is 10 kg lighter than the previous model. 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 Showa Big Piston Fork (BPF) suspension for a more progressive brake-dive. The 2010 ZX-6R is changing once more with an improved engine and slipper clut…

Kawasaki reintroduced the ZX-6R 636, while still continuing to sell the regular, 599 cc 2009-2012 ZX-6R at a lower price. The 2013 ZX-6R 636 is a brand new bike, making it the model with the most power output to date.

Has some updates consisting of: Euro 4 compliance, KQS quickshifter (up only), updated bodywork and seat, LED headlights and updated dashboard. The claimed horsepower also sees a slight drop from the 2018 model's 96.4 kW (129.3 hp) to 94.9 kW (127.3 hp).
