This purchase is for a set of engine guards for the above bike model. The steel tubing are braced together and is bolted to the sub frame of the bike. The steel tubing has multiple attachment points preventing them from rotating in the event of a low side. The aluminum skid plates can be easily and inexpensively replaced in case of a low side. There is no need to replace the whole guard. We use thick gauge tubing and highest grade bolts 12.9 (177,000 psi in tensile strength) wherever possible. Rest assured that you are getting the best material available.
