Stock rubber cushion always comes loose and fall off when we removing the tank. This newly developed cushion has a tighter fit and stays put whenever you moving off your fuel tank.
1. The new one made of Polyurethane, got better durability and longer lifespan
2. No more tank loose caused by the friction between the tank and stock rubber cushion. The fuel tank will stay firmly on the frame.
3. The stock one has a larger center hole so usually fall off when you removing the fuel tank but ours measure precisely so it wonít even move a bit after you put it on!
