Yup, transport. They were produced as work a day plodders. Then dudes like Johnny Brittan got his hands on the then new swinging arm suspension Bullet and won a bunch of trophies and medals ISDT and SSDT and stuff. Then later this other guy Steve Linsdell set a couple IOM records with a Bullet that still stand today. The Bullets designer Tony Wilson-Jones was a brilliant engineer. He was also a hech of a a mechanic and competition trials rider. I think he snuck some hidden potential into the design when the board of directors were looking the other way.
