This won't stand up to serious off-road use. I mostly ride gravel and stay away from bumps. Bought about 99 percent oil filter protection against stones. Hiway needs to be removed to change the oil filter and I cut a 1 1/2 inch hole with it. Leave the saw on the drill to access the oil plug to change the oil. The first oil change I had to grind the mounting studs on the 4 bottom mounting bolts. Replaced with stainless steel screws. I hope this solved the problem with these
