The
 SpeedyMoto frame slider kit includes an extremely durable 17-4 stainless steel engine studs. Precision-ground, thread-formed and quenched and 
tempered to an aircraft grade tensile strength of 185,000 psi, our bolt 
far surpasses OEM specs (as well as other manufactures) in both strength
 and wearability. 
We employ stainless steel for the integral 
engine nuts and slider support, not unlike the high-strength engine 
bolts used by Ducati race teams. Corrosion resistant and strain-hardened
 stainless steel is ideal for the crucial applications of holding your 
motor in, supporting the entire chassis, and providing a reliable 
platform for the actual slider. 
SpeedyMoto uses High Density Poly
 Ethylene (HDPE) plastic for the slider puck. Unlike other plastics, the
 unbelievably low friction coefficient of this plastic makes it 
practically glide on the pavement. By using this material the risk of 
'grabbing' is reduced, avoiding turning a smooth lowside into the 
dreaded catastrophic high side.
