2020 KX65


KX - The Bike that Builds Champions

For more than 30 years, Kawasaki’s smallest KX motocross bike has played a key role in the sport of motocross, providing a race-winning platform on which countless national and world champions have begun the journey to superstardom.

Today, Kawasaki’s KX65 maintains the same successful attributes, including a powerful and reliable two-stroke engine, lightweight chassis, disc brakes and long travel suspension. Its reputation as the quintessential learning tool for young racers taking their first steps into the world of competitive riding is well deserved.

64cc Two-Stroke Engine

Built for competition and to put them out in front of the pack. Easy, competitive operation to assist in building motocross riding skills.

Digital ignition rotor features rare-earth magnets, making it smaller, lighter and more durable. Its low inertial moment improves low-rpm response. High capacity ignition coil delivers a higher secondary voltage for a hotter spark, and the punchier response improves acceleration. Primary gear is secured using a lock-nut to help reduce mechanical noise. The oil seal of the left crankcase has a stopper for increased engine reliability. Metafoam gaskets are used for the generator cover, water pump cover and water pump elbow for improved sealing.

Front and Rear Disc Brakes

A high-performance engine needs high-performance stopping power and the KX65’s mighty front and rear disc brakes deliver powerful braking performance and high resistance to fade. A re-designed front brake lever now also offers even better feel. Large 180mm front and rear disc brakes with single piston calipers for superb braking performance. The rear brake has O-rings sealing the pivot for smooth operation.

Bottom-Link Uni-Trak Rear Suspension

The KX65’s UNI-TRAK® rear suspension system features a rising-rate action increasing the damping strength as the suspension compresses. The nitrogen-charged shock offers 4-way rebound damping adjustability, a stiff spring, and damping settings to accommodate aggressive riding.

Lightweight Aluminium Rims

Aluminum rims reduce unsprung weight and their strength adds durability. The KX65 receives black aluminium rims just like the larger KX models: KX450 and KX250. The aluminium reduces unsprung weight for improved suspension action.

33mm Conventional Fork

Front fork springs and damping settings reduce bottoming for more aggressive riding. The large 33 mm inner tubes assure rigidity for great handling on rough courses. Four-position rebound-damping adjustment accommodates different riding styles and terrain. Suspension built to reduces fatigue, improve line holding and create confidence.

24mm Mikuni Carburetor

Feeds a 4-petal reed valve for excellent throttle response. Helps the engine to produce good power and torque at all rpm.

Fuel Tank Check Valve

The fuel tank cap vent hose has a check valve to reduce the possibility of fuel seepage.

Digital Capacitor Discharge Ignition (CDI)

Digital ECU precisely controls timing, no matter how fast the rpm changes. Special ignition coil produces hot spark to enhance acceleration.

Optional Parts

Optional parts available include a 0.37mm carbon fibre reed petals, various carburettor jets, front and rear spring and sprockets.  All to ensure the KX65 is set-up right for the rider.

6-Speed Transmission

The KX’s smooth-shifting six-speed transmission offers a positive shifting action along with rugged durability thanks to hard chromed shift forks. The clutch is operated manually for maximum control and performance. The ends of the shift forks are hard chrome finished for durability. A bearing that is sealed on one side is used on the shift drum to raise the transmission's oil level for increased lubrication.

Multi-Plate Clutch

The clutch actuation arm rides in needle bearings for smooth action. The clutch basket and hub ride on involute splines and are fastened with a circlip . The steel clutch plates have a special surface treatment to improve the feel. Manual clutch mechanism mirrors larger KX models.

Electrofusion Cylinder

Electrofusion coating on the aluminium cylinder walls improves heat transfer for consistent power output. It allows closer piston-to-cylinder clearances for more power and provides excellent wear and seizure resistance.

Aluminium Silencer

Silencer is removable, and packing is replaceable. Oval shape mimics the styling of larger-displacement KX model.

High Tensile Steel Semi-Double Cradle Frame

The high-tensile steel frame is constructed from the same strong, lightweight, high-tech materials as the bigger KX Motocross bikes to offer exceptional torsional rigidity for great handling. Reinforced downtube adds strength and durability. The engine and chassis bolts feature a rust-resistant coating.


Large cast steel footpegs are designed to resist bending and offer great grip.
