This purchase is for a set of bottom engine guards for the above bike model. The kit does not come with the upper set of guards. The steel tubing has four attachment points each preventing them from rotating in the event of a low side. They are also braced together in the middle to further increase the strength of the guards. 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.
