Will fit both models with forward or mid-controls. You can even re-use the stock hardware. The Billy Boy outer primary is available in raw aluminum with a chrome derby cover, black with chrome or black derby cover and chrome with chrome or black derby cover.
Chrome derby cover hardware provided ( Chrome )Seals not included to be ordered separately.) The company also offers vintage looking air filters, transmission and cam covers for Big Twins and Sportsters. MSRP $629.00. US Info at 916-872-3189 or Esteves Motorcycle Design.
