Motor knee sliders will not damage your motorcycle suit or motorcycle pants if you go diagonally through the bend. Your knee often comes so close to the ground that it touches th asphalt. The kneeslider provides just a little distance between your motorcycle pants or motorcycle suit and the asphalt. Therefore, replace them in time!
Often knee sliders are made of TPU (Thermoplastic polyurethane) composite material, combined with an extra durable component. Titanium can also be used for extra hardness.
You have regular knee sliders, but also special knee sliders for in the rain. These have a better friction performance in wet conditions. They are often twice as thick compared to the regular knee sliders.
