KX65 Motocross

Many of today’s Supercross champions began their careers riding youth-sized off-road motorcycles at Pee Wee tracks and recreational areas across the country. From Jeff Ward to James Stewart, every one of them daydreamed of loading up the truck with dad and heading out to ride.

The Kawasaki KX™65 is made just for them. With its liquid-cooled, high-performance two-stroke engine, full-race chassis, long-travel suspension and disc brakes, the smallest KX model is the starting point for young riders who want to emulate their Supercross heroes.

The heart of the KX65 is a liquid-cooled, 64cc two-stroke engine matched to a smooth-shifting six-speed manual transmission and manual clutch.

The engine is bolted into a semi-double-cradle steel frame, and like the larger KX models, the KX65’s swing arm uses the UNI-TRAK® linkage system, which applies progressively stiffer damping and spring rates to the single rear shock as the suspension is compressed. The shock and fork boast four-way adjustable rebound damping for optimal handling.

Lightweight aluminum rims reduce unsprung weight to help improve suspension action, and both wheels feature hydraulic disc brakes that not only provide great stopping power, but require little maintenance and simplify wheel removal. Plus, the KX65 features a new two-tone seat, just like the new KX450F.

Youngsters who race their KX65 at designated events are eligible to receive support from Team Green™, Kawasaki’s amateur racing support program. Each year, Team Green provides regional support vehicles and highly trained technicians at more than 100 events, offering technical information and assistance to those who race Kawasaki products. Kawasaki also offers a comprehensive contingency program for amateur and professional riders who place well at designated events.

Engine Modifications for 2006
- Digital ignition offers ideal timing for better response across the rev range
- Magneto with lower inertial moment improves low-rpm response
- Rotor comes with rare-earth magnets – the unitized piece is small, lighter and more durable
- Revised ignition coil delivers a higher secondary voltage for a hotter spark; the punchier response gives an improved acceleration feeling
- Connecting rod big-end bearing has more rigid cage for improved durability
- Primary gear is now secured using a lock-nut to help reduce mechanical noise
- A stopper has been added to the oil seal of the left crankcase for increased engine reliability
- Metafoam gaskets are now used for the generator cover, water pump cover and water pump elbow to improve sealing

Electrofusion Cylinder
- Advanced exhaust and transfer ports for increased power and performance at higher rpm
- Bridge between exhaust ports is machined for improved reliability and resistance to seizure
- Lightweight cylinder liner transfers heat efficiently

Liquid Cooling
- Large radiator provides more even-running temperatures, keeping the power output consistently strong
- Provides greater reliability

24mm Mikuni Carburetor
- Feeds a four-petal reed valve for excellent throttle response
- Allows the engine to produce more power and torque at all rpm

Six-speed Transmission

- Exceptional torsional rigidity for superior handling
- Reinforced downtube for increased durability
- Engine and chassis bolts have new rust-resistant coating

UNI-TRAK® Rear Suspension
- Features rising-rate action: as the suspension compresses, the spring and damping strength increase progressively for a more controlled ride

Nitrogen-charged Shock
- Four-way adjustable rebound damping improves handling on rough tracks
- Rebuildable aluminum body
- External reservoir helps maintain consistent damping

Front Fork
- Four clicks of rebound-damping adjustment accommodate different riding styles and terrain

Swingarm
