BEC Mini
It's listed as a Busa mini but no engine with it AFAICT, so maybe a cheaper bike engine could be fitted. It even has De-dion rear suspension
rather than the Z Cars fully trailing arm design which I've always thought was a bit crude.
Looks like it could do with some more "frame" at the front otherwise the suspension will be a bit floppy!
yeah it's hardly ready for locost suspension is it? though he does say the floors done so perhaps these pics arn't the latest ones.
