Preload & RAPs

The preload can be adjusted with an electric Remote Adjustable Preload (RAP) or a manual RAP. The electric RAP typically comes with the RoadWing and is part of the set-up on the Honda Gold Wing.

The RAP can stiffen or soften the ride. It does lift the bike, a little but that is not the main purpose of it. Ideally, adding a RoadWing increases the weight capacity improves handling and eliminates the bottoming out issue with the original Road Star suspension.

Electric RAP

In order to use the electric RAP you will need to create or purchase a harness. Chris Jones (the creator of the RoadWing) makes and sells them.

Manual RAP

Since the the manual RAP comes from a used BMW rear mono shock on a 650, 1100, 1150 or 1200 they are extra. Sometimes the guys that convert them have them or you can search for one on eBay.
