hey Ive always been interested in FMX riding. ive ridden BMX's and Mountain bikes for about 3 or 4 years now and kinda wanted to step it up. thing is ive never riding a motorbike. ive been looking around FMX forums and a lot of people recommend a 250 but it is still possiable to ride FMX on a 125. what should i be looking at as far as a bike and other gear? any other info would be greatly appreciated too.
