Hey I'm new to riding, I work on a farm, my boss has a 100 acre pasture that we built a dirt bike track on where his kids ride. I've started riding around the pasture with his sons KXL 140 and I just ride it to learn. I want a bike of my own, and I want a taller bike that isn't to fast for me cause I'm a beginner, so I wanna mess around on it but also go around the track sometimes. I'm 17, 5' 10" and about 155lbs. What bike should I get?
