like a fool i jumped to conclusions and baught a set of NRG wheels for my project, i need a drum brake rear to fit 140mm shoes
Yeah only 125s had big drums so only really sr, typh or runner wheels I think I remember PSN doing runner caliper brackets that you can weld on some time back might be worth a try if you aren't keen on the drum..
Gilera runner fx 125/180 rear wheel and a early runner 50 front wheel (same speedo drive as typhoon) will make the typhoon handle lovely.
