2009 Kawasaki KX™85 Monster Energy®
Monster Energy graphics give instant credibility to aspiring champions
Under the black plastic, frame and wheels, green hubs and Monster Energy® graphics—just like the big KX’s—the Kawasaki KX™85 Monster Energy allows budding racers to look like their Kawasaki racing heroes while following in their developmental footsteps. With this in mind, the KX85 Monster Energy is a perfect choice for young racers to continue building upon their skills and venture into the next level of motocross completion.
The KX85 is powered by a liquid-cooled, two-stroke, single-cylinder 84cc engine that churns out race-winning power, and is packed with high-tech features, such as an Electrofusion-coated cylinder with a narrow squish band and large volume combustion chamber to enhance top-end power.
Fuel delivery for is provided by a 28mm Keihin carburetor that features a crescent-slide to position the needle closer to the intake ports. The Kawasaki Integrated Power-valve System (KIPS®) and tuned exhaust pipe contribute to the KX85’s tractable power delivery, which translates into better drive off the corners and more control for young riders of varying skill levels.
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’s smooth-shifting six-speed transmission really shine.
The KX85 utilizes a high-tensile steel perimeter frame, with a specially designed gas tank that sits inside the frame, lowering the fuel load and center of gravity for improved handling –yet another beneficial feature borrowed from KX85’s larger siblings.
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 proven UNI-TRAK® rear suspension system.
Those who race their KX85 Monster Energy edition 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.
