2013 Kawasaki KX85

The Serious Path to Motocross Glory

When the time comes for every budding motocross racer to decide that being a winner is why he or she races, then the next step is obvious. Throwing a leg over the KX™ 85 not only carries Kawasaki’s motocross heritage with it, but speaks volumes about how serious the racer is about taking the checkered flag.

The KX85 is powered by a two-stroke, 84cc engine that puts out eye-popping power. Among its race-proven features are an advanced chassis package with a 36mm cartridge fork that has 18-way compression damping adjustability and settings designed to tame the nastiest, most challenging tracks. The Uni-Trak® shock in back features fully adjustable spring preload, compression and rebound damping for superior rear wheel control.

Surrounding all that suspension goodness is a black-painted, high-tensile steel perimeter frame with a specially designed fuel tank sitting inside the cage to keep the fuel load and, thusly, the center of mass as low as possible for improved handling. All this is wrapped in lime green body panels, with lightweight black aluminum wheels and aggressive graphics. The result is a factory-look racer with factory-like performance.

The engine bay features some factory-like tricks of its own, including an electrofusion-coated cylinder with a narrow squish band, a large-volume combustion chamber to boost top-end power, and a 28mm Keihin carburetor featuring a crescent-shaped slide that positions the needle closer to the intake ports, optimizing fuel atomization and delivering smoother fuel delivery throughout the powerband. Further enhancing the KX85’s tractable power are the Kawasaki Integrated Power-valve System (KIPS®) and tuned exhaust pipe that provides better drive out of corners and a linear power delivery for young riders of varying skill levels.

The KX85’s six-speed transmission delivers smooth and positive shifting along with enhanced durability thanks to hard chrome-finished shift fork ends, a thick base on the clutch basket housing and an additional bushing on the input shaft.

Those who race their KX85 at designated events are eligible to receive support from Team Green™, Kawasaki’s amateur racing support program. For over 30 years, Team Green has provided regional support vehicles and highly trained technicians at more than 100 events per year throughout the United States, 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.

Authentic Kawasaki Accessories are available through Kawasaki dealers.
