Features Compact 65cc two-stroke engine features the same race-winning technologies found in the YZ125 and YZ250 motocrossers. Patented Yamaha Power Valve System combines crisp bottom-end torque with potent mid-range and free-revving top-end. Tuned Hitachi Astemo® Keihin PWK28 carburetor and reed-valve induction improves acceleration and throttle response. Digital CDI system delivers precise spark and monitors engine speed to ensure optimal timing for excellent response. Six-speed, close-ratio transmission optimizes gear ratios for maximum performance. Compact radiator delivers maximum cooling efficiency even in the toughest racing conditions. A compact steel cradle frame offers light, neutral handling and excellent bump absorption in the roughest track sections. Lightweight, removable aluminum subframe is constructed of square-section tubing for reduced weight and convenient maintenance. A 36mm KYB® coil spring fork offers excellent compliance with settings based on Yamaha’s extensive testing experience. Adjustable linkless shock design is light and compact and works through a swingarm with YZ125-style chain adjusters. Dual wave-style brake rotors are lighter than conventional rotors while offering a full size YZ family look. Maxxis® Maxxcross SI tires offer good grip across a variety of conditions, utilizing 60/100-14 front and 80/100-12 rear tire sizes. Adjustable ergonomics include a four-position aluminum handlebar clamp, adjustable clutch and front brake levers. Long, flat seat design, smoothly integrated body panels and grippy foot pegs combine to aid rider movement. The YZ65 packs in the same aggressive styling as its larger YZ siblings, even down to the slick blue Excel® wheels.
