Buell XB 9/12 08-10 Engine slider kit. For the left and right side engine protection. Complete kit comes with all hardware. Look here for the complete kit

Material = UHMW-PE (ultra high molecular weight polyethylene) and a aircraft grade aluminum  6061-T6 bracket finished in black anodizing for durability.
Special feature: The pucks are solid and not hollow, made to withstand a greater impact. Brackets are designed NOT to rotate in a lowside.
Slider dimensions: approx. 2.5" and 3" in length and 2" in diameter.
NO CUT or plastic fairings modification required.

A set of frame sliders for the above bike model. The sliders feature a  new design of a complete solid puck without a hollowed-out center. This increases the  strength and contact surface to about 30%. The bracket is bolted to the engine mount and the slider puck is bolted onto it. The brackets have four attachment points preventing them from rotating in the event of a low side. The material of the puck is made  of UHMW-PE (ultra high molecular weight polyethylene), a tough plastic with good strength,  wear resistance and dimensional stability. It is more dimensionally stable than Nylon and  used in many industrial ball bearing and friction reducing applications. Compared to Delrin,  it is softer but tougher. Delrin is harder but more brittle. It is an ideal material for  frame sliders since it can absorb more impact force onto itself and therefore reduce the  impact on the frame and engine. The slider pucks can be inexpensively replaced in case of a  low-side. 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..
