It keeps your motorcycle on the go in some of the roughest terrain, whether it’s the precision of a cleverly crafted motocross track or the raw appeal of nature’s finest trails.

    You cant beat the value for this tusk cluch cover. It was really easy to install and and only took 20 minutes of my time. The looks are finaminal. And I couldn't be more excited to ride with this cover. Because I know that it will protect my bike way better than the stock cover and it will protect me from a huge head ache in the woods where if I did have this strong billet aluminum tusk clutch cover. Then the clutch cover would have a hole in it.
