If you ride your 2005-2006 GS offroad、 you NEED this part! A big low-slung engine、 with no ’frame’ protecting it requires the best protection you can get. Steel structure spreads the load between more mounting points and also places an 8mm thick energy absorbing rubber cushion between the engine and the rocks. This engine guard is essential for maximum protection for serious off-road adventures. Best protection with the large skid plate 044-0305. Very straightforward installation. 2007 & newer bikes have modified & stronger skid plate attachment so this item is not as crucial.
