I fancied a C50 when I was commuting 20 odd miles or so in the early 80's to reduce fuel costs, however being 6'-0" and 18 stone I doubt if the little motor would pull me up a hill. Think I'd be a bit top heavy these days.
Oh it would, brilliant little engine, remember a friend having one in the mid 70's we were following him on our SS50's when suddenly his back wheel locked up & it slid to a stop. We stopped & the engine had seized, we asked if he had put any oil in, his reply was it's a 4 stroke it doesn't need any oil, we then went onto explain not oil in the fuel but in the engine/gearbox, No was the answer he's not checked it in 8 months since he bought it new. However we let the engine cool down, jumped on the kickstart a couple of times & it freed itself off, we went off to the car shop up the road & bought some oil, filled it up & off we went. He was still running around on it 5 years later when the last I saw him. He was a big lad as well, probably in your region.
