2012 Kawasaki KX85 Review

The 85cc-class mini-motocrosser has long been the training crucible for the world’s top racers. For much of that time, Kawasaki’s KX™85 has been at the forefront. The level of technology, power and berm-busting capability packed into this 152-pound rocketship is mind-boggling, and the way it can tear up a motocross track in an expert’s hands must be seen to be believed. It’s nothing short of a youth motocrosser’s dream machine.

The Next Step for Future Champions

With an impressive power-to-weight ratio and a compact, nimble chassis, it’s no wonder that the KX™85 is the bike of choice for riders getting serious about motocross competition. The 85cc class has long been the proving ground for many of the top riders, and the KX85 has helped them gain mastery of the track.

This little rocket ship 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. Each year, Team Green provides regional support vehicles and highly trained technicians at more than 100 events 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.

– Liquid-cooling assures even-running temperatures, consistent power output and greater reliability
– Bridges between intake and exhaust ports are machine-finished for increased durability
– Rotor utilizes rare-earth magnets – the unitized piece is small, light and more efficient; low inertial moment improves low-rpm response
– Connecting rod big-end bearing has a more rigid cage for improved durability
– Intake port shape and cylinder skirt allow cooling air into the crankcase chamber
– Primary gear is secured using a lock-nut to help reduce mechanical noise
– Metafoam gaskets for the generator and water pump covers improve sealing

Kawasaki Integrated Power Valve System (KIPS®)

– KIPS system varies exhaust port height for increased horsepower and torque at all rpm
– Produces a broad powerband with more low-end torque while retaining excellent top-end power
– Breather in KIPS cover improves high-rpm and overrun performance

28mm Keihin Carburetor

– Crescent slide carburetor puts the needle closer to the intake ports for optimum throttle response
– Adjustable for various conditions

Clutch

– Clutch hub rides on needle bearings for smooth action
– Large clutch plates measure 119mm in diameter for added durability and control
– Clutch-release lever ratio provides light clutch lever action
– Thick clutch basket housing improves durability

UNI-TRAK® Rear Suspension

– Swingarm uses large cross-section beams for more rigidity and control
– Swingarm incorporates cast-aluminum drive chain adjuster sections for easy chain adjustments
– Flanged collars at the bearings to protect seals from mud
– Fully adjustable shock with compression damping, rebound damping and spring preload adjustability

36mm Inverted Cartridge Fork

– Aluminum upper tubes are 49.5mm in diameter for excellent control and steering response
– Compression damping is 18-way adjustable

Disc Brakes

– Front brake lever shape offers better feel
– Forged-aluminum rear brake pedal is strong, lightweight and features two seals at the pivot for smooth operation

Lightweight Aluminum Rims
