I took my bike to a new independent shop to have the Angel GT's installed. The tech there worked at a local dealer and he commented about something that a Team Kawasaki driver for the demo truck told him. The driver said after awhile the comments on the new C14's as far as rough ride kept popping up so now the demo units have rear shocks that have 15-20K on them and everyone seems a little happier with the ride. Talk about overbuilt! Most stock suspensions are toast by 15-20K.
