Kawasaki KMX

The Kawasaki KMX is a water-cooled 2-stroke trail bike. There are two versions, the KMX 125 cc and the larger 200 cc edition.

They both feature front and rear disc brakes, water-cooled engines, mono link suspension (Kawasaki's Uni-Trak system) and a power valve system (KIPS).

Models: A1-A5/B1-B12

The 125 cc can be ridden in some countries with just a provisional license as they come restricted to 12 bhp (learner legal spec.)

They are quick bikes once de-restricted and the power will be increased to over 20 bhp at the rear wheel easily reaching 85 mph with some modifications to the gearing ratio (sprockets).
