MachineartMoto AVANT Front Fender Extender for R1200GS and R1200GS Adventure The MudSling-AVANT is a patent pending front fender extension that adds 5.25 of length to protect the front of the bike from mud, water, tar, and rock splashback. The AVANT is unique in that it mounts without the need to drill holes in the fender, unlike other fender extensions. Not only is it simple to install with the included three grip clamps and black coated screws, it looks beautiful and integrates with the stock fender and is transferable to another bike without leaving disfiguring holes behind. The AVANT installs with three compression clamps secured with T25 Torx head screws, included with the fender. Made from injection molded in resilient polypropylene, it is shaped with characteristic flared wings that widen the splash coverage area without looking wide. The surface finish beautifully matches the stock BMW fender.
