Yamaha WR | YZ Skidplate: The Molecule Motosports Yamaha WR250F | WR450F | YZ250FX | YZ450FX UHMW skidplate is hand built in the USA from billet UHMW, a precision fit engineered specifically for these bikes. UHMW offers superior wear resistance compared to aluminum without cracking or deforming, and it slides effortlessly over rocks and logs. Choose the Standard skidplate for lightweight, proven protection, or step up to the OverBilt for a heavy duty option built for extreme terrain and hard rock impacts.

Made from billet UHMW, our plates deliver superior wear resistance compared to aluminum and even carbon steel. This material will not crack, puncture, or let you down, and better yet, it is self-lubricating, helping you slide over obstacles effortlessly. Do not compare this to HDPE or aluminum. UHMW is lighter, slides better, and holds its shape under abuse.

For added protection, our optional one-piece linkage guard helps you glide smoothly over rocks and logs. Whether you are a hardcore hard enduro racer or a technical backwoods trail rider, this feature makes a noticeable difference.

Skidplate Options:

This product is available in two configurations: Standard and OverBilt.
