Or if you're talking about different linkage setups, then there is the stock link, no-link, and CR500 link. The stock link is obvious, it's the stock linkage, shock, swingarm, and frame. The no-link doesn't use a linkage and requires an aftermarket frame, swingarm, and shock. The CR500 link requires an aftermarket frame, swingarm, shock, and linkage.
Most all aftermarket chassis companies offer all of these configurations, e.g. Laeger, Lonestar, Walsh, Roll Design, etc., etc.
Well the main part that I am interested in, is the part that connects to the outside of the shock and then connects back to the frame.
Looks some what like a U shape. Not sure what this part is called.
I needed to get something done on that part because the 2 pressed in bushings on the ends were worn out pretty bad. What I ended up doing was taking out 1 of the bushing and that linkage part to a machine shop to have new ones made. Besides Honda wanted over $200. for the entire assembly when all I need was those bushings. Now I installed them late last night and theres no more play in that part of the linkage at all...its like new again.
