The rear sets are from a 929 honda. I am not a big fan of the way I did the linkage and thinking of changing the setup as the bike may be steam punked in the near future. Gears, cables or chain and sprockets would be used instead of linkage. I can send the dimensions and what it takes to build. You need to weld up a few items and machine a few bits but there is no frame modding with this setup.
