With more amateur national championships than any other brand, the Kawasaki KX™ 85’s pedigree already outshines its competition, but for 2014 a new KX85 raises the bar higher than ever. In fact, the one thing that hasn’t changed is that the KX85 is still the ultimate training tool for the Ryan Villopotos of tomorrow. Box-stock, it’s ready to win championships!

At A Glance…

• NEW Retuned liquid-cooled, two-stroke, 85cc engine produces 20% more peak power than previous model

• NEW Revised Kawasaki Integrated Power-valve increases more mid-range torque and top-end power

• Uni-Trak® rear suspension is fully adjustable for compression and rebound damping and spring preload

• Rigid 36mm inverted cartridge forks are 20-way compression damping adjustable and provide better steering response and control

• Revised jetting in the 28mm Keihin PWK carburetor helps give ideal fuel atomization, for 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

• Clutch-release ratio is designed for light clutch lever action

• Clutch plate service cover simplifies maintenance and utilizes a metal-carbon composite gasket

Six-speed Transmission

• 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

• High-tensile steel tubing is reinforced in key areas to optimize durability and weight

• 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 with 24-position compression and 21-position rebound damping, plus stepless spring preload

36mm Inverted Cartridge Fork

• NEW shim-type valving provides more precise damping control

• NEW firmer damping rates offer superior bottoming resistance

• Inverted fork is rigid, providing better steering response and control

• Compression damping is 20-way adjustable

• Aluminum upper fork tubes measure 36mm in diameter for flex-free performance

• Revised axle clamp reduces under-hang for greater fork clearance in ruts

Disc Brakes

• NEW petal-type brake rotors (220mm front/184mm rear) increase stopping power

• NEW petal-type rotor design helps clean the brake pads for more consistent performance
