Engine

The cylinder head on the 85cc two-stroke engine has many power-inducing features such as a shallow combustion chamber and Nikasil-plated cylinder with a large exhaust port optimized for gas flow. The single-ring piston design helps to reduce cylinder wall friction for superior throttle response.

The KX85’s factory race-replica character is supported by the 28mm Keihin PWK carburetor, which features a crescent-shaped slide to positions the needle closer to the intake ports for optimized fuel atomization.

The KX85 also employs the Kawasaki Integrated Power-valve System (KIPS®) to boost mid-range and top-end power with its independent slider valves for each port, replacing a previous three-piece design to reduce maintenance and improve reliability.

The 83mm crankshaft features a precisely shaped resin block to close the gap around the machined area near the crank pin. This helps boost power as well as making the crank more rigid and durable.

Because power generates heat, the KX85 radiator provides ample cooling capacity, prolonging engine life and providing consistent power delivery during grueling motos.

The smooth-shifting six-speed transmission has the perfect ratios for tackling any obstacle on the track, while durability is assured thanks to its hard chrome-finished shift fork ends, thick base on the clutch basket housing and additional bushing on the input shaft.

Chassis

It takes a race-proven suspension package to put the KX85’s horsepower to the ground, and the Uni-Trak® linkage, KYB reservoir shock and inverted KYB 36mm forks are up to the task of tackling the roughest motocross terrain. They utilize 24-position compression and 21-position rebound damping adjustment, along with stepless spring preload to help ensure the rider can tune the handling to his or her preference.

Just like its big brothers, the KX85 front forks features shim-type valving and firmer damping for the faster riders, while also offering superior bottoming resistance as well as 20-position damper adjustment settings to suit a variety of riding styles and track conditions.

In the rear, the shock’s black-anodized aluminum body has a clicker-type adjuster to make fine-tuning the rear suspension damping quick and easy.

The petal-type brakes improve the stopping power, with 220mm front and 184mm rear rotors delivering efficient braking performance and the petal shape helps clean the pads in muddy conditions.

The front brake hose is routed behind the axle for better protection using hose guides. The KX85 runs on Dunlop® Geomax MX51 intermediate tires to provide optimal grip over varying terrain and riding conditions.

The KX85’s high-tensile steel perimeter frame has reinforcement in key areas to maintain the Kawasaki’s legendary handling. Its 32.7” seat height fits a wide variety of growing inseams, and there is plenty of adjustability thanks to a wider and taller handlebar, three-position risers and two-position clamps to provide six different handlebar positions to ensure a comfortable fit for the rider.

The KX85 looks as fast as it runs, thanks to bold factory race styling that is virtually identical to the big KX models. The low fuel tank, slim radiator covers and side panels blend with a flatter two-tone seat with seamless cover and grippy material to ensure the rider is both comfortable and able to move freely.

An angular front fender, number plate and white rear fender not only match the big KX models, but the front fender also helps reduce mud accumulation, while wrap-around fork guards protect the inner fork tubes and seals. Last but not least, a brushed finish on the aluminum swingarm helps keep the KX85 looking fresher for longer.

Completing its factory-race styling, the KX85 is finished in Kawasaki’s signature Lime Green with eye-catching detail appointments such as green alumite coatings on the adjusters and black alumite coating on the rims, just like Villopoto’s factory KX™ 450F.

Those who race their KX85 at designated events, Kawasaki will continue to offer the same support to racers of all ages and levels that it has for more than 30 years. The Team Green™ support program has given riders the tools for success by providing technicians and support staff at a number of selected events throughout the year. Team Green also provides racers with unparalleled trackside support and emergency parts for last-minute adjustments. While helping amateur athletes achieve success, Kawasaki never forgets its most important goal is to ensure a positive and enjoyable experience for every rider.
