SMT’s custom Harley Davidson motorcycle wheels are all milled from forged billet aluminum DOT certified American-Made blanks. We also offer custom matching air cleaners, pulleys, rotors, cush drive hub, and sprockets.
We can even mount on your wheel an Avon, Metzeler, Shinko, or Vee Rubber tire.
Our S&S air cleaners fit Harley and Indian bikes.

There is no substitute for the quality, fitment, and design of the custom motorcycle rims you will receive from SMT Machining. Due to the fact that every order is a custom order, please allow 8-10 weeks of manufacturing time. This will ensure the perfect fitment of your custom wheel.
