Engine

• Powerful-feeling 65 cc single-cylinder, liquid-cooled, 2-stroke engine with crankcase reed valve.

• Overall design creates excellent ride character and performance

• Yamaha Power Valve System (YPVS).

• Mechanical power valve system delivers effective exhaust timing throughout the entire rev range

• Provides excellent power and torque characteristics

• Delivers responsive acceleration just as the rider intends

• Slit-shaped valve on the side of the exhaust port operates in response to engine rpm

• In low-to-mid-rpm range when exhaust timing is slower, valve moves to cover the top part of the exhaust port

• In high rpm range when quick exhaust timing is needed, valve recedes and exhaust port is fully uncovered

• Valve control governor from YZ125 and YZ250 employed

• 2-petal reed valve.

• Optimized crankshaft balance and lightweight connecting rod.

• Resin weight in crank web creates high primary compression ratio and optimal inertial mass

• Delivers instant power delivery and reduced vibration

• Specialized intake manifold and exhaust pipe.

• Optimal intake and exhaust layout complies with racing regulations

• Short exhaust produces rippling sound unique to a 2-stroke

• Expansion chamber designed for plenty of volume

• Design pays special attention to pulses that occur during combustion flow to contribute to explosive but easy-to-use power

• Exhaust complies with FIM/AMA regulations

• Optimized ignition output produces a stronger, more consistent spark throughout the entire rpm range

• Model-specific CDI unit.

• Digital CDI system delivers precise spark and monitors engine speed to ensure optimal timing for excellent response

• Short-type spark plug.

• Short design offers better service ability and performance

• 6-speed transmission with optimized gear ratios.

• Ideal number of clutch plates and spring load gives clutch lever a light pull

• Gear ratios fine-tuned for performance

• Fine-tuned air cleaner box.

• Keihin PWK28 carburetor with revised settings (compared to YZ85).

• Downsized radiator (compared to YZ85). * Drive chain with new dimensions (compared to YZ85).

Chassis/Suspension

• Semi-double-cradle steel frame and aluminum subframe.

• Dimensions, rigidity balance and synergy with suspension equals handling that feels light and stable, and willing to lean over in turns

• Lightweight, bolt-on aluminum subframe contributes to mass-centralization

• Inverted 36 mm KYB front fork with 215 mm (8.5 in) of wheel travel.

• Design combines handling with a light, stable feel and a solid connection to the ground

• 36 mm inner tubes ensure planted feeling when entering corners and excellent shock absorption when going over bumps

• Outer tubes made of aluminum alloy for excellent rigidity and front-end feel

• Adjustable compression (12 levels) and rebound (10 levels) damping to fine-tune handling and performance on the track

• Aluminum steering stem developed for rigidity balance

• KYB link-less Monocross rear suspension with 270 mm (10.6 in) of wheel travel.

• Design provides smooth damping feel and doesn't bottom out when absorbing shocks

• Shock absorber has 10 levels of adjustment for both rebound and compression damping to fine-tune handling and performance

• Aluminum swingarm.

• Rigidity balance is tuned for YZ65's frame, delivering light handling feel and easy lean-in characteristics

• Swingarm end designed with ease of maintenance in mind

• Resin chain guard designed not to get caught up in ruts that the small wheel will travel through

• Tapered aluminum handlebar with 4-position adjustability.

• Handlebar adjusts 27 mm to match a child's growth

• Handlebar crown made of cast aluminum for light weight and strength

• Seat designed for comfort and easy maintenance.

• Seat design facilitates body weight transfer for enhanced on-track performance and rider confidence

• Single bolt under the seat cushioning makes seat removal easier

• Bodywork based on high-end YZ models.

• Body panels have a soft, gentle look

• Styling follows the YZ design language of horizontal lines

• Colours and graphics similar to the flagship YZ450F

• Wave-style disc brakes.

• Sporty wave-style rotors are lighter than conventional rotors and offer improved self-cleaning action in dirty conditions

• 14-inch (front) and 12-inch (rear) blue Excel rims with Maxxis SI tires.
