the builder of this bike had it on our stand at Copdock a few years ago.
The build quality is OUTSTANDING. He built the frame himself around a Royal Enfield headstock I believe.
The engine was ALREADY CHOPPED when he got it, so what do you do?. Build another Norvin or let your imagination run wild and personalise your own bike.
Although this look like a rigid frame it is actually sprung with the swinging arm cleverly disguised under the seat.
Please do not judge the builder by the use of a chopped engine..John
