Introducing the YZ65 - designed for winning performance and unrivaled durability to lead a new generation of bLU cRU riders into the victorYZone.

Additional Features

  • ADJUSTABLE ERGONOMICS: The YZ65 is highly tune-able to fit riders of various sizes, with a 4-position adjustable aluminum taper 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.

Chassis / Suspension

  • COMPACT STEEL FRAME: The YZ65 offers light, neutral handling built on an all-new steel cradle frame. Designed around the rigidity balance required for the 65cc class, this new frame delivers excellent grip feeling even across bumpy track surfaces, 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.
  • SUSPENSION SYSTEMS: Up front, a 36 mm KYB® coil spring fork offers unmatched compliance with settings based on Yamaha’s extensive testing experience. Out back, a new link-less shock design is light and compact to suit the needs of 65cc-class riders, and controls a new 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.


  • TWO-STROKE ENGINE: The 65 cc two-stroke powerplant is for the 2018 YZ65, and 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 features optimized hose routing to deliver maximum cooling efficiency even in the toughest racing conditions.

  • 65CC MOTOCROSSER: Built from the ground up for 2018, the YZ65 is ready to tackle the track with winning performance right out of the gate. And, of course, the YZ65 features Yamaha's renowned competition off-road quality and durability just like the bigger YZs.
  • ENGINE: The 65 cc two-stroke engine features Yamaha's legendary YPVS, mechanical power valve system for a broad spread of power and torque across the entire RPM range.
