Twin Air Airbox Power Cover YAMAHA YZ250F 24-25, YZ450F 23-25, WRF/YZFX250 2025, WRF/YZFX450 24-25

Twin Air has developed a new PowerCover for the latest generation of the Yamaha YZ250F, YZ450F and Fantic XXF 450. The new PowerCover enhances air flow into the airbox creating an even inflow of fresh air. The result is increased throttle response and top-end max power.
