This purchase is for a set of engine guards for the above bike model. We have improved quality and strength the engine guards by adding some more features. These new engine guards feature six attachment points (three on each side) and are braced together in the middle to prevent them from rotating in the event of a low side. The engine guards also come with a set of replaceable skid plates that can be inexpensively replaced without purchasing a new set of steel guards. Think of them as protection for your protection! We use highest grade commercially available 12.9(177,000 psi in tensile strength) wherever possible. Rest assured that you are getting the best material commercially available.
