2023 Yamaha YZ250F

The multi-championship-winning YZ250F dominates on the race track, at the shootouts and basically everywhere it goes. And with the Monster Energy Yamaha Racing Edition, privateers can have that factory look whether on the practice track or the starting gate.

The YZ250F's liquid-cooled, DOHC 4-valve, fuel-injected powerplant features a forward-positioned straight downdraft intake with symmetrical intake/exhaust ports, high-spec piston, aggressive cam profiles and reversed cylinder head layout. The advanced four-stroke engine is known for its broad, useable powerband and class-leading low-end and mid-range torque.

The free-of-charge Yamaha Power Tuner app brings the power of the GYTR® Power Tuner to your iOS® or Android® device. Using wireless connectivity to talk to the bike’s onboard CAN-bus network, the app allows owners to adjust air/fuel mixture and ignition timing maps to tune engine performance for track conditions, record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more.

The YZ250F's aluminum bilateral beam frame features main spars, engine mounts and mounting position that are designed to centralize mass and provide an ideal balance between cornering feel and straight-line rigidity.
