2009 Kawasaki KX85

The next step for aspiring champions

Whether it’s a growing, young rider building upon a foundation of skills or an older beginner seeking to start racing, the Kawasaki KX™85 is the perfect motorcycle for the next level of motocross completion. A budding racer’s dream, 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 are features that provide enhanced durability and 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 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

Liquid-cooled, two-stroke, single-cylinder 84cc Engine
– Lightweight Electrofusion-coated cylinder improves heat transfer while resisting abrasion and seizure
– Bridges between intake and exhaust ports are machine finished for less wear and improved reliability
– Liquid-cooling means even-running temperatures and consistent power output
– Rotor comes with rare-earth magnets –the unitized piece is small, light and more efficient with low inertial moment improves low-rpm response
– Connecting rod big-end bearing has 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 and mid-range, while retaining excellent top-end power
– Breather in KIPS cover improves high-rpm and overrun performance

– Thick base clutch hub rides on needle bearings for smooth action
– Large clutch plates are 119mm in diameter for durability and control
– Clutch-release lever ratio is designed for light clutch lever action
– Clutch plate service cover simplifies maintenance and utilizes a metal-carbon composite gasket

28mm Keihin PWK carburetor
– Large crescent slide carburetor positions the needle closer to intake ports for excellent throttle response and improves power
– Adjustable for various conditions

– Large right-side cutout improves airflow for increased power
– Reusable foam air filter

Exhaust System
– Features large-diameter O-ring and groove on exhaust pipe for improved durability and easy installation
– Aluminum silencer is re-packable like larger KX models

Six-speed Transmission
– Positive shifting action and rugged durability
– Fifth and sixth gears on the input shaft ride on bushings for added reliability
– Shift forks are hard chrome finished to resist wear and seizing
– Convenient oil level window
– Bushings on the second, third and fourth gears on the output shaft increase durability

High-tensile Steel Perimeter Frame
– Wide footpegs for better control, made of cast steel for strength
– Thick footpeg mounting brackets withstand today’s rigorous tracks
– Engine and chassis bolts have rust-resistant coating

Fuel Tank
– Gas tank design lowers center of gravity for improved handling

UNI-TRAK® Rear Suspension
– The swingarm uses large cross-section beams for improved rigidity and control
– Cast-aluminum drive chain adjuster sections for easy chain adjustments
– Shock is fully adjustable for compression and rebound damping and spring preload

36mm Inverted Cartridge Fork
– Inverted forks are rigid, providing better steering response and control
– Compression damping is 18-way adjustable
– Aluminum upper fork tubes measure 49.5mm in diameter for flex-free performance

Front and Rear 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 and increased durability
– Strong braking power is achieved with minimal effort

Front and Rear Wheels
– Rear hub features two wheel bearings on the drive side of the hub for durability
– Rear-axle diameter is large for more rigidity

– Aggressive Kawasaki Lime Green and Black graphics just like larger KX models
