Comrade Justin:. 50 as in 50 mph on real gps is very fast...best to measure it before taking a bow...I def know 50 on a modded Tomos is definately real. My st a55 remains with original jug cdi etc with just air Intake , jetting and pipe and does 43 all day. That's with a Tomos rate limiting cdi. So measure and post. I've got a couple of 50 plus mopeds and 50 scares me on a moped. Honestly. Buy leathers wear a full face helmet consider a leatt neck brace if speed is your ultimate goal.
