???? 2027 Yamaha YZ250F

All-new for 2027 and built to dominate. The 2027 Yamaha YZ250F takes Yamaha’s championship-proven 250 four-stroke motocross platform to the next level with a completely redesigned engine, new YZ450F-derived aluminum frame, hydraulic clutch, updated KYB suspension, lighter rear brake system, and advanced smartphone tuning.

At its heart is an all-new 250cc liquid-cooled DOHC four-stroke engine with fuel injection. For 2027, Yamaha increased power and torque throughout the rpm range while raising the rev limit by 700 rpm. A redesigned intake, higher compression ratio, new double-spring intake valves, and dry-sump lubrication system help support the increased performance while revised intake and exhaust systems meet current FIM/AMA noise requirements.
