Perfect for any W800, W650, W400. The package also uses W bike as a model so when I saw that it gives me assurance. For the W tank, you will need to buy 2 meters. I was worried about washing and rain that the water might be trapped inside but after installation, I feel relieved. The liner is although very soft and flexible, is not possible to install by hands. I hurt my hands and fingers trying to push it only that it will come out. My gut knowledge told me I need to use a rubber hammer and BAM! It fits so snugly that water should be able to penetrate. It's so tight fit you won't worry it will come out. Highly recommend for all retro bikes.
This is better than the cheap ones offered by generic chinese sellers. The color is deep black and looks better in real life in the pictures on webike suggest which look kinda grayish. The price is even cheaper than the OEM moles. One of the best finds on webike. I recommended many friends to get this rim to protect their tanks.
