I used this only during the winter last year and stored it in a warehouse, so it's in good condition with no wear or fading. Product Description: Hot Hand Warmer This hand warmer is compatible with off-road bikes with handguards, naked bikes, and big scooters. *1. The lining has a waterproof film and shirring at the entrance to prevent rainwater from entering. Materials: Barrier Cloth, 600D, Barrier Nylon Cloth, PVC, Taffeta, Compressed Urethane, Chloroprene Important Notes: The parking lever on some big scooters may be difficult to operate when this product is installed. If the outer diameter of the grip is thick or has a special shape, operational problems may occur due to the steering cover. In that case, discontinue use of the steering cover. It may not fit depending on the vehicle model or the size of the handguards. Are you looking for information specific to Rufus AI? Thank you for viewing.
