Our custom chrome rims are made from high quality aluminum and then go through a final CNC process to add in the layer details that make our rims one of a kind. They are then polished to perfection to removed any defects. Once polishing is completed they go through a six stage chrome process to provide the show quality chrome finish. Fits most Chinese clone based scooters with a 13x3.5 wheel with rear disc brake. Can also be used if you want to upgrade from the standard 12" wheel that came on earlier models. Note: Not recommended for install on rear brake drum scooters. If you are unsure about fitting on your scooter please confirm fitament by contacting us before making purchase.
