I just gave one to a friend, had really neat chainset wth the Norman invaders on it, was all chrome, but the lugs left a lot to be desired, Go into Norman Bikes you will get Motor bikes they have some info on the bikes with the history etc, Norman did make some lightweight models the Invader was one, I also remember my Dad in Birmingham had a Norman Motor bke, went like the clappers, noisy too, Cheers John Crump Oldbrit, Parker Co.USA
