Friends bike is one year old, and now the rear suspension is binding when it's compressed in the garage, havn't had time to look at it yet. It seems to travel so far down and then stop or bind up some.. He has never greased the rear linkage, swingarm, etc.. My first guess is something is seizing up in that area. If that's the issue, how much are the rebuild kits, and where is good place to order them? Or is there something else to check?
