KX - Junior Motocross Performance

Amateur or professional levels, Kawasaki is dominant in mini-motocrossing, with many of today's top professional riders getting their start on KX minicrossers.

Kawasaki continues this tradition by offering ready to race green meanies.

High performance engine and race ready suspension, adjustable handlebar positioning and slim bodywork, the KX85 is the bike to beat.

36mm Inverted Fork

The fork offers race proven damping and bottoming resistance, enabling higher-paced riding and contributing to increase rider comfort. Front suspension performance has been stepped up to the next level thanks to Accumulating Shim-Type Valving - the same system as used on full-size KX models. Black forks guards like the larger KX models for a factory look.

Front and Rear Petal Disc Brakes

For the ultimate in style, the KX85 features petal shaped discs just like the full size KX250 and KX450 models. A 220mm disc at the front and 184mm at the rear provide massive stopping power.

Uni-Trak Rear Suspension

The rear shock contributes to a stable ride feel, and offers easy adjustability and light weight. Black spring and green anodised adjusters add to the factory look.

KX85 Seat

Slim Flat Seat Design

The minimalist bodywork, flat slim fuel tank design and the flat seat were designed to make it easier for racers to go fast. Combined with a low positioned fuel cap, enables easier body transitioning from the front to the rear of the motorcycle.­

Powerful 2-Stroke Engine

The 85cc 2-stroke liquid cooled high performance engine in the KX85 utilises numerous high performance design features, a low friction single ring piston for high power and sharp throttle response, the cylinder is designed with the Kawasaki KIPS system and the cylinder head features a high performance combustion chamber design.



Styled after the full-size KX250/KX450 models, the KX85 features sleek, aggressive bodywork designed for stunning, aggressive looks. Its streamlined shape takes the ease of rider movement and weight positioning to a whole new level. Factory style graphics complement the sharp high performance design.

Large Radiator for Extra Cooling

The KX85’s radiator has been built to match the engines performance, working hand in hand with the power output. Keeping it all cool when the racing action is getting hot.

6-Way Adjustable Handlebar Position

An adjustable handlebar allows riders to custom-fit their riding position Mounting brackets feature 2-position forward-backward adjustment while optional spacers allow 3-positions of height adjustment.

6-Speed Transmission

The KX’s smooth-shifting six-speed transmission offers a positive shifting action along with rugged durability thanks to hard chromed shift forks and new bushings added to the second, third and fourth gears on the output shaft.

Kawasaki Integrated Power Valve System

The KIPS system varies exhaust port height for increased horsepower and torque. A breather in KIPS cover relieves exhaust pressure for more precise valve action and improved high rpm performance. KIPS lever stopper spring absorbs governor “over stroke” for added durability. The KIPS governor has a long stroke to open the cylinder valves more fully.


Pull-type clutch actuation for smooth operation and easy maintenance. The right hand engine cover provides a separate clutch cover for quick servicing without removing the water pump.

Style and Flair

The slim bodywork and racy graphics ensure the KX85-II will look good in the winners’ circle. Black alumite rims, black fork guards, black rear spring and green anodised finish on the suspension adjusters further strengthen their factory image.
