2009 Kawasaki Ninja on 2040-motos

For 2009, 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. 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 Showa Big Piston Fork (BPF)^[4] suspension 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.

2013 Ninja ZX-6R 636

For 2013, 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. Engine displacement has again been increased to 636 cc, with two fuel maps available to choose via a switch on the handlebars. The new version has increased torque and horsepower, and the increased performance is apparent at lower RPM. While the tail is to the one in the 2009-2012 model, it features new front and side fairings, new dash, new frame, new Showa BPF-SFF front suspension, KTRC (Kawasaki Traction Control) with three modes (sport, city and rain) as standard equipment, and KIBS (Kawasaki Intelligent anti-lock Brake System) available as option.

In Showa's BPF-SFF (Big Piston Fork - Separate Function Fork) suspension, the left leg bar a bigger and stronger spring than the right one, with regulated pre-load. The right bar has bigger oil damper section, with regulated rebound and compression damping. According to the manufacturer, this asymmetric design provides a reduction of the friction inside the fork, significant mass loss and more friendly response of suspension. The KTRC system uses manipulation of the ignition timing on all 3 traction control modes, while mode 3 (rain mode) also uses a separate throttle controlled by the on-board electronics, to allow faster reaction for wheel over-spin on slippery surfaces. Traction control and power modes can be adjusted or turned off whenever the throttle is closed, even while riding the bike. The bike is sold without a steering damper, as Kawasaki reports that people complained about the OEM steering dampers in the previous model, so they decided to not include one into the new bike.
