I still have my old 79 CM185T... put 12000ish kms on that bike in 4 years... It's smaller then a cbr125 and my stepmom (who's 5'2) can flatfoot while seated...
In theory I could cruise at 65mph... with a tailwind... downhill...
I suppose I looked pretty weird going down the road... hitting your knee with the handlebars was always annoying...
