These are not “mushrooms”! Unlike most of our competitors, we use de-embrittled high-tensile steel bolts which are designed to bend on impact rather than to shear or snap. In addition, we add compression sleeves inside the bobbins which are designed to allow the retaining bolts to be torqued to the correct specification and not to work loose though vibration. Constructed of heavy-duty machined steel, aluminium, and high-density nylon, R&G frame sliders provide maximum protection and high quality fit and finish. R&G “Aero” sliders have an aerodynamic teardrop shape for a more streamlined look than traditional cylindrical sliders. The protector itself is machined from High Density Polyethylene (HDPE) – chosen because as it wears it actually helps to slow a sliding bike. The bolts used are also de-embrittled steel; working as a shock absorber to bend instead of snapping or staying rigid – which could twist the mounting point. THIS KIT COMES AS A PAIR – LEFT & RIGHT HAND SIDES FIXING BOLTS INCLUSIVE. With bespoke designs for over 350+ models of motorcycle there is bound to be an application for your bike.
