KX85 II Features

Revised Shroud Design

Shrouds designed to accommodate a wider range of riders make it easier for riders to find a good fit on the bike.

6-Position Handlebar

A choice of six positions allows riders to tailor their riding position.

Increased Cooling Performance

The new shroud design more efficiently directs air to the radiator, contributing to cooling performance.

Slim Ergonomics

Minimalist bodywork, flat tank and slim, flat seat were designed to facilitate moving around on the bike.

Stronger Transmission

Complementing the increased power of the KX85-I engine is an all-new transmission – a change that also benefits the KX85-I.

Factory Inspired Styling

Like Kawasaki’s top motocross models, bold, functional looks reflect these models’ race-winning potential. The new shrouds contribute both to ergonomics and the aggressive styling. Factory-inspired touches like black alumite rims and green alumite suspension adjusters strengthen the KX family resemblance.

Multiple Size Options

Riders can choose from two available wheel sizes: the KX85-II feature 19” front and 16” rear wheels; the KX85-I is equipped with a 17” front and 14” rear.
