I had been in contact with Scootworks for over a year regarding their drive. They kept saying it is in testing and will be available in a month. After several months of this I got the reply "The America is now completing it's field testing, and the Speedmaster is in development." That was in August, still no drive available. I would have bought the pulleys off Scootworks and sourced my own belt but the rear sprocket on a Bonneville is different so I don't know how they say it is compatable. I don't know about swing arms being different lenghts between model years, seems odd to me.
Bought the QDP drive, it took 6 weeks to arrive.
