The crash pads by Renner are made of high quality aluminum and plastic. The plastic-made sliders have a high strength, so that the energy is absorbed in a fall as high as possible. Thanks to the Controlled Flexion Area, the frame or the engine block does not bend immediately in the event of a fall, but the holder or screws bend at predetermined predetermined breaking points in advance. The fastening screws are very different in their strength, so that the threads of the frame or engine attachment points are not damaged in a fall as possible.
