These R&G CP0366BL Aero Style Frame Sliders, Black are made specifically for the BMW S1000R (2014-2016).
These "Aero Style" frame sliders have been made of heavy-duty machined steel, aluminum, and high-density nylon. R&G racing frame sliders provide maximum protection and high quality fit and finish. R&G "Aero" sliders feature an aerodynamic teardrop shape for a more streamlined look than traditional cylindrical slider pucks.
The protector is machined from High Density Polyethylene (HDPE). Actually it 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.
