32 fields on record
The Yamaha YZ65 continues as the step-up youth motocross model above the PW50 for 2027, powered by a 65cc liquid-cooled, reed-valve two-stroke fed by a Keihin PWK28 carburetor through a 6-speed manual gearbox. At a claimed 134 lb wet weight and a 29.7-inch seat height, it bridges the gap between beginner minibikes and full-size 65cc competition machines.

How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It exists purely for motocross track and off-road competition, designed to teach race craft, throttle control, and clutch/gear management on a 2-stroke.
- Built for
- Expect a peaky, high-revving 2-stroke power delivery that rewards aggressive clutch work and precise shifting, paired with featherweight agility ideal for tight track sections and jumps.
- Not ideal for
- This bike is not suitable for adult commuting, highway travel, two-up riding, or any road use since it is an unregistered, off-road-only youth race machine.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
