Sound insulation material standard insulation material sp 250gr. std

For 2-stroke motorcycles The amount of filling (= tight / loose filling) is very important for noise reduction and the lifespan of the silencer material. Too "soft" filling: the exhaust initially has a soft sound, after a short time the silencer material has collapsed in one place, then an empty space is created, the silencer makes more noise again and the silencer material wears out very quickly. Too "tight" filling: long service life of the silencer material, but not optimal sound insulation. The general lifespan of the material depends on the vehicle and rider. Tip: Weigh the weight of the damper after filling and check the weight every two hours. Fill up again with the determined amount of weight loss! Empty silencers reduce performance, cause more noise and often cause consequential damage! Sound insulation material fulfills 3 functions: sound insulation, heat insulation, prevents fatigue fracture of the perforated pipe due to vibration. Important: When washing the vehicle, please always ensure that the damper is properly closed to prevent water from entering. Damp or wet muffler material dramatically increases vehicle noise levels! Dirt loads due to unburned oil or oil residues caked in the damping material affect the sound insulation.
