Potent 65cc Motocrosser
Built to win races, the YZ65™ is ready to tackle the track with winning performance right out of the gate. And, of course, this compact machine features Yamaha’s renowned competition off-road quality and durability just like the bigger YZs.
The 65cc two-stroke engine features the legendary Yamaha Power Valve System (YPVS), a mechanical power valve system that delivers a broad spread of power and torque across the entire RPM range.
With a strong steel frame and adjustable front and rear suspension, the YZ65 offers riders the traction, confidence, and tunability of full-size motocross machines in a compact package.
Potent Two-Stroke Engine
The 65cc two-stroke powerplant features the same advanced technologies found in Yamaha’s race-winning YZ125 and YZ250 motocrossers.
Proven reed-valve induction improves acceleration and throttle response across the entire powerband, with a carefully tuned Keihin® PWK28 carburetor to meter fuel flow.
Yamaha Power Valve System
Patented YPVS™ combines crisp bottom-end torque with potent midrange and free-revving top-end, making the most of the compact engine and lightweight chassis.
Six-speed, close-ratio transmission optimizes gear ratios for maximum performance, giving riders the right gear for every race condition.
Digital CDI system delivers precise spark and monitors engine speed to ensure optimal timing for excellent response.
Efficient Cooling System
Compact radiator delivers maximum cooling efficiency even in the toughest racing conditions.
Compact Steel Frame
The YZ65 offers light, neutral handling built on a strong steel cradle frame. Designed around the rigidity balance required for the 65cc class, this frame delivers excellent bump absorption in the roughest track sections, jump landings and whoop sections.
Removable aluminum rear subframe is constructed of square-section tubing for reduced weight and convenient maintenance, just like on the full-size motocross bikes.
Adjustable Suspension Systems
Up front, a 36mm KYB® coil spring fork offers excellent compliance with settings based on Yamaha’s extensive testing experience. Out back, a link-less shock design is light, compact, and works through a swingarm with YZ125-style chain adjusters. Both front and rear suspension systems are tunable for both rebound and compression damping.
Dual Wave-Type Disc Brakes
Wave-style brake rotors are lighter than conventional rotors and have that full size YZ family style.
Maxxcross SI tires offer good grip across of a variety of track conditions, utilizing 60/100-14 front and 80/100-12 rear tire sizes.
