I think the America comes with slightly longer control cables than the Speedmaster. At least when I stretched out a purchased Pinwall, America clutch cable along side of my original Spdy cable, the America cable was 1-3/4" longer, as I rerouted the throttle cables to the other side of the frame spine, they were long enough. My point is that America bars on a stock Spdy may not be completely plug and play. Feel free to correct me as that's how we learn.
