i like the honda crs they are fast an dependable i used to ride trails alot an anything else seemed to break down alot .honda cr s are fast the only one who might be faster is yahmaha but they over heat alot.
if you want to race get a kawasaki kx 65 there very fast, but if you just want to ride get a crf or xr 100 (almost the same size as the kx and probably better for a begginer.) im 13 and 90 pounds and im gonna get the 100 when i sell my old one.

My first bike was a Suzuki RM 85.. its a great bike and has a lot of power. You may want to start on an 80.
an 80cc or 85cc. get a yamaha suzuki kawisaki honda or ktm.
