Kawasaki z1000

In 2007 Kawasaki released an updated version of the Z1000. The bike features a detuned version of the relatively outdated Kawasaki ZX-9R engine. This detuning, in addition to the design of the exhaust, provides less top end compared to the super-sport ZX-9R engine, but more low to mid rpm range, giving a stock '07-08 Z1000 a top speed of about 149mph and 0-60mph acceleration in about 2.9 seconds, with about 125bhp at 10,000rpm. Kawasaki successfully addressed complaints of engine vibrations, and provided a much smoother ride on the '07-08 models compared to the '03-06 models.
