Bonneville America Forums Forums Off Topic Discussion Forums Lounge Compatability between 2007 and earlier Speedmaster

99% of anything you want will fit all the Speedmasters or Americas. 07 had some cosmetic changes and the 865 engine has a different cam. You could still put a cam from the 790 in the 865 it's a pollution thing. the 07 also has a catalyst in the pipes. The rear peg hangers look different but are interchangeable with the older ones same for the front peg mounts. Alloy wheels on the 07s are different the upper fork shrouds are tapered on the 07 bottom line is the stuff you want will fit.
