This purchase is for a set of engine guards for the above bike model. This increases the strength and contact surface to about 30%. The steel tubing is bolted to the sub frame of the bike. The steel tubing has four attachment points preventing them from rotating in the event of a low side. It is ideal for engine guards since it can absorb more impact force onto itself and therefore reduce the impact on the bike. We use highest grade commercially available 12.9(177,000 psi in tensile strength) wherever possible. Rest assured
