There are no current aftermarket rearsets that I'm aware of beyond the Brammo rearsets designed for racing. The racing rearsets are nice as they have a lot of adjustability and the shift linkage can be set up for traditional or GP (reverse) shift pattern.
However, there are a couple of issues:
1. The rearset was not designed to accommodate a kickstand mount for road-use.
2. The parts are manufactured in very low volumes, so prices are high. Still - If you're interested please send me a PM and I'll send you a quote on the parts. It might be that someone could take our design to another manufacturer and come up with something more cost effective for everyone else.
