Sand, rocks, soil, loam, playing in the dirt comes naturally to kids. It’s just that while some kids are happy to build roads through it with their toy dump trucks, others crave an earthmoving style that’s a little more… efficient.
The 2018 YZ65 utilizes a new 64.8cc liquid-cooled, two-stroke engine that features a case reed-valve intake and a mechanical Yamaha Power Valve System (YPVS). Designed for performance and ease of use, the new YZ’s engine also provides confidence to go the distance thanks to Yamaha’s unparalleled durability and reliability.
Proven reed-valve induction improves acceleration and throttle response across the entire powerband, with a carefully tuned Keihin® 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 features optimized hose routing to deliver maximum
cooling efficiency even in the toughest racing conditions.
All-New Chassis and Optimized Ergonomics
The newly-designed semi-double-cradle steel frame, removable aluminum subframe and aluminum swing-arm of the YZ65 provide a nimble feel and confident handling. The ergonomics feature a flat, comfortable seat and four-position adjustable aluminum tapered handlebars to provide comfort and ease of movement for a wide range of young rider sizes. Continuing in the YZ design language of horizontal lines, the styling of the body, color and graphics are like those of Yamaha’s flagship YZ450F.
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.
Removable aluminum rear subframe is constructed of square-section
tubing for reduced weight and convenient maintenance, just like on the full-size motocross bikes.
Easily Tuned KYB® Coil Spring Suspension
Up front, a 36mm 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.
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.
The YZ65 is highly tunable 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.
