The TWIN AIR Radiator Sleeve is crafted from nylon-coated fiberglass material. This innovative design effectively prevents dirt, sand, and mud from entering the radiator, thereby protecting it from overheating. The sleeves are easily slipped over the radiator fins (after removing them), and the elastic bands ensure a secure fit. The TWIN AIR Radiator Sleeves are compatible with a wide range of popular motorcycle models from KTM, HUSQVARNA, GASGAS, KAWASAKI, HONDA, YAMAHA, SUZUKI, and more. Each package includes two sleeves (one for the left side and one for the right side).
