I have ridden quite a few standard RC45s and loads of modified/standard RC30s over the last 20 years. I find my NC30/35 suit me now, but if I wanted a riding bike , then an RC30 with HRC, [Superbike carb/duct, kit wheels, i/l valves, piston rings] plus the usual Micron, Spondon, Ohlins would be good...
