2027Yamaha YZ250
40 fields on record
The Yamaha YZ250 continues as one of the last two-stroke motocrossers in Yamaha's lineup for 2027, powered by a 249cc liquid-cooled, reed-valve two-stroke single fed by a Keihin PWK38S carburetor through a constant-mesh 5-speed gearbox. At a claimed 227 lb wet weight, it keeps the light, high-revving character that two-stroke loyalists still seek out on the motocross track.

How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for motocross track riding and competitive off-road racing, not for general transportation.
- Built for
- A raw, punchy two-stroke motocrosser that rewards aggressive riding, precise clutch and throttle control, and delivers explosive mid-to-top-end power with razor-sharp agility.
- Not ideal for
- Not suitable for commuting, highway travel, passengers, or riders wanting plush comfort and low-maintenance simplicity.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
