it was the dream 50 .... single cylinder dohc ... twin exhaust ...restricted 30mph....unrestrictet stage1..40mph stage two with special cdi unit ...~50mph .....race tuned with parts from takegawa (other cams, head , bore up kit 90cc bigger manifold an carb ,special exhaust, 6 speed gearbox , nos kit , full fairing ) over 80mph , downside the parts alone add up to about ~£2500 but then it`s aproper race replica
and you will be very lucky to get a used one for under £2000 no matter what condition

but by the look of it you could get the tank and seat and rear light and front light and clip ons , possibly the half fairing to fit on your cg :-)
