Conquer Dirt

With an all-new engine, new frame, new bodywork, electric start, Power Tuner app and more, the 2019 YZ250F is ready to roost the competition with features never before seen in the 250 cc class.


An updated cylinder head, piston, cam profiles, cylinder geometry and much more work together to give YZ250F riders the best balance of high-rpm power with a broad, useable powerband.

Yamaha's bilateral beam frame features new main spars, engine mounts and engine mounting position to further centralize mass and provide an ideal balance between cornering feel and straight-line rigidity. Class-leading suspension features revised settings to match the YZ250F's updated frame and engine layout.

2018 YZ65 heritage Highlight ImagePOWER TUNER APP

Yamaha broke new ground when the Power Tuner app was introduced on the 2018 YZ450F, putting flexibility and precision tunability into your smartphone. This technology carries over to the 2019 YZ250F, allowing riders to make fueling and ignition timing changes instantly and upload them to the bike via the onboard Wi-Fi system. It's the ultimate in trackside tuning!
