i´m 5ft 8 and it never bothered me everyone told me i look great on the bike but i have to say unless you have a lotta money hanging around and alot of mechanical knoledge and dont mind spending an hour by the side of a road at least once a week i wouldnt get an RS iv had mine just over a year and she has cost me an arm and a leg and was broken most of the time got to say tho when she was in working order they are a scream but remember they are extremely high maintanence bikes there racing bikes there to highly tuned to potter about day to day i strongly advise against getting one if u want a sporty 125 what about a sach xtc (which will do over a ton de restricted but are really reliable) or a honda cbr or nsr. anyways good luck with it all what ever your choice.
