2013 Kawasaki KX85

With the KX85 , you’ll not only carry Kawasaki’s motocross heritage, but you’ll also carry a serious riding experience, one that few bikes in its class can replicate. Combining style with performance, the KX85 is really in a class of its own.

At the heart of the KX85, you’ll find a two-stroke, 84cc engine that is useful enough to produce high power. It comes complemented with a superior chassis package along with a 36mm cartridge fork that has 18-way compression damping adjustability. Furthermore, the Uni-Trak shock system, the adjustable spring preload, compression and rebound damping offers superior rear wheel control that you won’t find anywhere else.

To provide smooth shifting and advanced durability, the KX85’s six-speed transmission is helped by hard chrome-finished shift fork ends, a thick base on the clutch basket housing and an additional bushing on the input shaft.

The Kawasaki KX85 offers tremendous support from the company’s very own Team Green racing outfit and on top of that, you’re offered a comprehensive contingency program for amateur and professional riders who place well at designated events.

Features of Kawasaki KX85

Kawasaki KX85
  • Liquid-cooled, two-stroke, 84cc engine features a lightweight Electrofusion-coated cylinder that improves heat transfer while resisting abrasion and seizure
  • Kawasaki Integrated Power-valve System varies exhaust port height for increased horsepower and produces a powerband with more low-end torque and mid-range, while retaining excellent top-end power
  • Uni-Trak® rear suspension is fully adjustable for compression and rebound damping and spring preload
  • Rigid 36mm inverted cartridge forks are 18-way adjustable and provide better steering response and control
  • 28mm Keihin PWK carburetor is tuned for ideal fuel atomization, providing quicker throttle response and a smoother power delivery
  • Six-speed transmission has chrome-finished shift fork ends to resist wear and seizing while bushings on the second, third and fourth gears on the output shaft increase durability
  • Industry-leading amateur racer support through Team Green™

Liquid-cooled, Two-stroke, Single-cylinder 84cc Engine

Kawasaki KX85
  • Lightweight Electrofusion-coated cylinder improves heat transfer while resisting abrasion and seizure
  • Intake and exhaust port bridges are machine-finished for reduced 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; 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

Airbox

Kawasaki KX85
  • Large right-side cutout improves airflow for increased power
  • Reusable foam air filter

28mm Keihin PWK Carburetor

  • Carburetor adjustable for various conditions

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

Clutch

  • Thick-base clutch hub rides on needle bearings for smooth action
  • Large, 119mm clutch plates add 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

Six-speed Transmission

Kawasaki KX85
  • Positive shifting action and rugged durability
  • Fifth and sixth gears ride on bushings for added reliability
  • Shift forks are hard chrome-finished to resist wear and seizing
  • Convenient oil-level window offers easy level checks
  • Bushings on the second, third and fourth gears increase durability

High-tensile Steel Perimeter Frame

  • Wide, steel footpegs offer added control and strength.
  • Thick footpeg-mount brackets withstand today’s rigorous tracks
  • Engine and chassis bolts feature rust-resistant coating

Fuel Tank

  • Fuel tank design lowers center of gravity for improved handling

Uni-Trak® Rear Suspension

  • Swingarm uses large cross-section beams for improved rigidity and control
  • Cast-aluminum drive chain adjuster sections allow easy chain adjustments
  • Shock is fully adjustable for compression and rebound damping and spring preload

36mm Inverted Cartridge Fork

Kawasaki KX85
  • Inverted fork is 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

Disc Brakes

  • Front brake lever shape offers optimum feel
  • Forged-aluminum rear brake pedal is strong, lightweight and features two seals at the pivot for smooth operation and increased durability
  • Provide strong braking power with minimal effort

Lightweight Aluminum Rims

  • Black-coated lightweight aluminum rims offer a factory look
  • Rear hub features two bearings on the drive side for added durability
  • Large rear-axle diameter for optimum rigidity

Graphics

  • Aggressive Kawasaki graphics complement the black frame and wheels
