2025 KX65

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

Digital ignition offers ideal timing for optimal throttle response throughout the rev range. 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. Connecting rod big-end bearing features a cage for added durability. 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.

Silver clutch and ignition covers resist the signs of boot rub to help keep the KX looking fresh for longer

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.

Light and powerful. Ergonomic front brake lever shape offers easy operation. The front and rear brakes resist fading.

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.

The KX65’s UNI-TRAK® rear suspension system features a rising-rate action that increases the damping strength as the suspension compresses. The nitrogen-charged shock offers 4-way rebound damping adjustability, a stiff spring (in Lime Green), and damping settings to accomodate aggressive riding.

The rocker arm is made of cast aluminium to save on weight. The bottom link design helps lower the centre of gravity, which makes the bike feel lighter and easier to handle. The external reservoir cools the shock fluid, increasing fade resistance to keep the damping consistent on the nitrogen-charged shock.

Aluminum rims reduce unsprung weight and their strength adds durability.
The 2016 KX65 receives black aluminium rims just like the larger KX models. The look of the 2016 KX65 is taken from the big brother KX450F and KX250F

The aluminium reduces unsprung weight for improved suspension action.

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.

The 2016 KX65 also receives candy lime green type II forks caps just like the KX250F and KX450F.

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

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 by hand for maximum control and performance.

The ends of the shft forks are hard chrome finished for durability. A bearing that is sealed on one side is used on the shift drum to help raise the tranmission's oil level for increased lubrication and added durability. A short shift lever to assist in quick gear changes.

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

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

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 instead of a bolt to ease servicing. The steel clutch plates have a special surface treatment to improve the feel. Positive action and rugged durability. Manual clutch mechanism mirrors larger KX models. Clutch cover gasket made of metal-carbon composite material.

Electrofusion coating on the aluminum 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.

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.
