Make sure you also buy the OEM honda shock bumpers... the standard hadley ones are not quite a good fit on the studs and bolts.. Shocks made by showa(iirc) for both honda and hadley..
Be very careful with that! The Harley shocks are standard and the Honda shock mounts are metric. It may look close and feel close but you are talking about a moving, functioning suspension that will test that close feel to the limit.
