The TWIN AIR Radiator Sleeve is crafted from a nylon-coated fiberglass material that effectively prevents dirt, sand, and mud from entering the radiator, thereby protecting against overheating. These sleeves are easily slipped over the radiator fins (requiring removal) and the elastic bands ensure a secure fit. Designed to fit a wide range of popular motorcycle models, including KTM, HUSQVARNA, GASGAS, KAWASAKI, HONDA, YAMAHA, and SUZUKI, the TWIN AIR Radiator Sleeves come in pairs (left and right). Ideal for riders seeking enhanced cooling efficiency and radiator protection on various terrains.
