The Black Dog Cycle Works Rugged Skid Plate for BMW R1200GS/GSA motorcycles has a new and unique design that eliminates the back rubber shear bolts that are typically threaded to the engine block and can cause extensive damage upon impact. The skid plate offers unparalleled protection of the engine case, alternator cover, frame and exhaust pipes. It’s designed to mount the rear of the skid plate vertically from the frame, which completely isolates the rear of the engine case from impact. The front of the skid plate is secured via a through-bolt on the front of the engine/frame, which is an extremely sturdy part of the bike’s design. Large rubber "Shok Bloks" between the skid plate and the bottom of the engine absorb the energy of significant impacts.
