alex... that is the dumbest thing I have ever read.
tomos started in yugoslavia
puch started in austria
tomos might give you the cheapest most reliable speed, a pipe and a carb gets them to 40-43
a puch needs a kit a carb and a pipe to hit 45 or so
on a puch the problem is the porting limits the speed. so if you know how to port and engine you might get better results with the stock cylinder.
