Features

Chassis / Suspension

  • 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.
  • LIGHTWEIGHT SUBFRAME: 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.
  • MAXXIS® TIRES: 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.

Engine

  • POTENT TWO-STROKE ENGINE: The 65cc two-stroke powerplant features the same advanced technologies found in Yamaha's race-winning YZ125 and YZ250 motocrossers.
  • RACE-DEVELOPED INTAKE: 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.
  • CLOSE-RATIO TRANSMISSION: Six-speed, close-ratio transmission optimizes gear ratios for maximum performance, giving riders the right gear for every race condition.
  • DIGITAL IGNITION: 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.

Other Features

  • ADJUSTABLE ERGONOMICS: The YZ65 is highly tunable to fit riders of various sizes, with a 4-position adjustable aluminum handlebar clamp, adjustable position clutch and front brake levers, grippy foot pegs, and long seat design to help riders move across the bike.
  • AGGRESSIVE YZ FAMILY STYLING: The YZ65 may be the smallest member of the family, but it packs in the same aggressive styling as the larger YZ and YZ-F siblings, even down to the slick blue Excel® wheels.

Top Features

  • 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.
  • YPVS™ POWERPLANT: 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.
  • ADJUSTABLE CHASSIS: 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.
