Note the system made by MotoWig is a single sided swingarm design that utlizes a rear paralever swingarm.(upper right)
The single sided swingarm leading link we built (bottom left) worked well but I was not happy with the pivot bearing design I used. It has an adjustble trail feature on it.
The thing is on hold right now due to work load etc. Once we get back on it we may put it on Sgt. Brown's K Monster or my R100R rig..not sure yet. It was first tried on a R100GS rig.
