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
With a carefully tuned Hitachi Astemo® Keihin PWK28 carburetor to metre fuel flow, the proven reed-valve induction improves acceleration and throttle response across the entire powerband.
Yamaha Power Valve System
Patented YPVS™ combines crisp bottom-end torque with potent mid-range 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.
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 aluminium rear subframe is constructed of square-section tubing for reduced weight and convenient maintenance, just like the full-size motocross bikes.
Adjustable suspension systems
Up front, a 36 mm 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 and compact and works through a swing-arm with YZ125-style chain adjusters. Both front and rear suspension systems are tunable for both rebound and compression damping.
Dual wave-type rotors
Wave-style brake rotors are lighter than conventional rotors and have that full size YZ family style.
Maxxis® tyres
Maxxis® Maxxcross SI tyres offer good grip across a variety of track conditions, utilizing 60/100-14 front and 80/100-12 rear tire sizes.
Adjustable ergonomics
With a four-position adjustable aluminium handlebar clamp, adjustable position clutch and front brake levers, grippy foot pegs and long seat design to help riders move across the bike, the YZ65 is highly tunable to fit riders of various sizes.
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.
