The 2017 KX85 is here and ready to continue the revolution. Kawasaki engineers have gone all-out to ensure the KX85 has what it takes to stamp its dominance on the Junior MX circuit.
With a high performance engine and race ready suspension, adjustable handlebar positioning and slim bodywork, the 2017 KX85 is the bike to beat.
The 85cc 2-stroke high performance engine, the engine design features a low friction single ring piston for high power and sharp throttle response, the cylinder is designed with the Kawasaki KIPS system and features high performance combustion chamber design in the cylinder head.
Styled after the full-size KX250F/KX450F models, the KX85 features sleek, aggressive bodywork designed for stunning, aggressive looks. Its streamlined shape takes the ease of rider movement and weight positioning to a whole new level. Factory style graphics complement the sharp high performance design.
Larger Radiator for Extra Cooling
The KX85's radiator has received a boost in capacity and efficiency to raise its output from 5.6kW (2013MY) to a huge 8.5kW. The large radiator keeps the KX85 running at peak performance.
Front and Rear Petal Disc Brakes
For the ultimate in style, the KX85 features petal shaped discs just like the full size KX250F and KX450F models. A 220mm disc at the front and 184mm at the rear provide massive stopping power.
Front suspension performance has been stepped up to the next level thanks to Accumulating Shim-Type Valving - the same system as used on full-size KX models. Noticable improvements include light and heavy shock absorption and less underhang below the axle. Green Alumite* finish on the adjusters just like the factory racers.
Race ready Uni-Trak Rear Suspension
An updated compression damping adjustment mechanism on the rear shock absorber improves damping force at slower stroke speeds for greater riding stability.
Flat Seat Design
The flat seat design, combined with a lower positioned fuel cap, enables easier body transitioning from the front to the rear of the motorcycle.Â
The KX's smooth-shifting six-speed transmission offers a positive shifting action along with rugged durability thanks to hard chromed shift forks and new bushings added to the second, third and fourth gears on the output shaft.
High-tensile steel perimeter frame
Setting the KX85 apart from the competition is its advanced, high-tensile steel perimeter frame. Its increased rigidity and lower centre of gravity (Thanks to a centralised fuel tank) adds up to superior handling and rider feedback.
Kawasaki Integrated Power Valve System
The KIPS system varies exhaust port height for increased horsepower and torque. A breather in KIPS cover relieves exhaust pressure for more precise KIPS valve action and improved high rpm performance. KIPS lever stopper spring absorbs governor "over stroke" for added durability. The KIPS governor has a long stroke to open the cylinder valves more fully. A governor spring and 8 mm bearing boss aid durability.
Thick base at the clutch housing fingers for increased durability.The right hand engine cover provides a separate clutch cover for quick servicing without removing the water pump.
Factory Racer Finishes
The rims are coated in black Alumite*, the rear suspension spring is lime green, the fork and rear shock adjusters have a candy lime green type II Alumite* finish just like the factory racers.
