Motocross KX 85

Spec

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, lightand 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
 
Clutch
- 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
 
Airbox
- 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 todays 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 featurestwo 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
