Engine displacement
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, Kawasaki Traction Control (KTRC) with three modes (sport, city and rain) as standard equipment, and Kawasaki Intelligent anti-lock Brake System (KIBS) available as option.
