Those of us who own BMW boxer’s know how pricey replacing a cylinder head cover can be, so the X-Head DOHC and the X-Head Cylinder Guards provide ample coverage for those expensive cylinder head covers if the bike is dropped. Molded from impact-absorbing nylon, these covers are designed to hit first, and install in less than 5 minutes with included hardware. The MudSling is designed to protect the shock and battery area from flying debris and helps keep your bike clean. Several versions of the MudSling are available for the R1200GS & GSA, the F800 / 650 GS twins and the R1200R. To make a match set on the front of your bike, the Avant is a front fender extension that functions as a guard for your exhaust and engine and installs without any drilling into your stock fender.
