Setup, Compatibility & Care
To install, ensure your engine is cool before handling the radiator area. Remove the existing plastic panels by unscrewing the OEM bolts, being careful to save all grommets and washers. Align the new Acerbis spoilers by starting with the upper mounting point, then secure the lower tabs gently to avoid cracking the plastic.
Compatibility includes: YAMAHA WR 250 F, WR 450 F, YZ 250 F, YZ 250 FX, YZ 450 F, and YZ 450 FX models across specified years. To maintain the panels, wash them with mild soap and water; avoid using high-pressure power washers at close range to keep the plastic finish from dulling.
