– 2006 Kawasaki KX85

2006 Kawasaki KX85

The 85cc class is one of the most competitive in amateur motocross. Good thing the Kawasaki KX85 is directly descended from the machines that have powered riders like James Stewart toward pro careers. For 2006, the KX85 have improved ignitions and KIPS® power-valve performance, new intake port shape and revised cylinder skirt, new tires for better grip, new front brake lever and more upgrades to keep your bike running ahead of the pack. But don’t just take our word for it, ask James Stewart who said “These small green bikes helped me get to where I am today.”

There’s a point when a young rider’s physical growth and developing skill on the race track demands a motorcycle that can do more than keep up with their competitive nature – they need a bike that can power them to the front of the pack. The Kawasaki KX™85 provides that leading-edge of power and performance.

The KX85’s liquid-cooled, two-stroke, single-cylinder 84cc engine churns out an abundance of race-winning power. It’s equipped with high-tech features, such as an Electrofusion-coated cylinder with a narrow squish band and large volume to enhance top-end power. A machined finish to the bridges between the intake and exhaust ports helps prevent seizure and improves engine reliability.

Fuel delivery for the engine is provided by a 28mm carburetor that features a crescent-slide to position the needle closer to the intake ports. A Kawasaki Integrated Power-valve System (KIPS®) and exhaust pipe capped with a KX250-style muffler contribute to the KX85’s tractable powerband, which provides control for riders of varying skill levels.

A smooth-shifting six-speed transmission, hard chrome-finished shift fork ends, a thick base on the clutch basket housing and an additional bushing on the input shaft for extra durability are all features that make the KX85 shine.

The KX85 stands above the competition with its advanced chassis. It utilizes a high-tensile steel perimeter frame, and a specially designed gas tank sits inside the frame, lowering the fuel load and center of gravity for improved handling – yet another design borrowed from the bigger KX motorcycles.

Long-travel suspension at both ends helps to smooth out the roughest course for riders of every size and skill level. The 36mm inverted cartridge front fork has the capability of 18-way compression damping adjustment. Out back, the spring preload, compression and rebound damping are all adjustable on the UNI-TRAK? rear suspension system.

And for 2006, the KX85 features aggressive Kawasaki Lime Green and Black graphics and a two-tone seat, just like the other KX models.

Those who race their KX85 at designated events are eligible to receive support from Team Green™, Kawasaki’s amateur racing support program. Each year, Team Green provides regional support vehicles and highly trained technicians at more than 100 events, offering technical information and assistance to those who race Kawasaki products. Kawasaki also offers a comprehensive contingency program for amateur and professional riders who place well at designated events.
