The tank is made of strong plastic and based on several owned by friends I'm counting on it lasting for years. The fit was not exact. It rested directly on the frame toward the rear on each side even though the stock rubber bumpers were properly placed. I had to manufacture some rubber spacers to lift to tank slightly off of the frame to fight damage from vibration. Also the radiator shrouds had to be flexed quite a bit to get the mounting bolts in. They may break too due to the stress they are under but they will not cause the ride to end if that happens. Perhaps they could supply larger bumpers to lift the rear of the tank off of the frame. Perhaps they could improve the mold so that the bolt holes line up better. With those two improvements the tank would be exceptional. As is I would rate it GOOD.
