2021 Kawasaki KX 100

The 2021 Kawasaki KX 100: Bridge To The Big Bikes

The 2021 KX 100 is designed by Kawasaki to be a bridging motorcycle, that is, to be able to give a young rider age 10+ their first feel of a top spec motocross racer. This 2021 off road bike is powered by a 99cc liquid cooled two stroke and set up from the factory to be an absolute devil in the dirt and be able to fly over jumps, absorb whoops, and carve the corners with the best of them. This engine also includes KIPS (Kawasaki Integrated Powervalve System), which replaces the need for a reed valve.

As expected from the Japanese company’s bikes, it is packed full of racing technology. Competition grade disc brakes, 11 inches of travel on front and rear fully adjustable suspension, with preload adjustment on the rear becoming available for the young racer. Kawasaki’s plan with the KX 100 is for the young rider to gain experience and maybe even a few wins, before stepping up to the junior pro bike, the KX250.

The 2021 Kawasaki KX 100 starts at $4,399 USD / $5,099 CAD.
