2025 Class Dominator
Featuring a high-spec piston, aggressive cam profiles and forward positioned intake cylinder head layout, the YZ250F’s advanced four-stroke engine is known for its broad, useable powerband and class-leading low-end and mid-range torque.
The aluminium bilateral beam frame is based on the flagship YZ450F and provides just the right amount of strength and flex for the perfect balance of stability and cornering performance. The result is a superb handling machine with lightweight feel and increased front wheel traction, allowing the rider to enter corners with greater confidence and more line choices.
