I am 13 years old and on the small side ( I'm 5'1" ) and I am looking for a 2 stroke dirt bike. I currently own and use a 2008 kawasaki klx 140L ( four stroke ), but I want something with a little bit more power and a powerband with some more "oomph". I was riding at a family friends track and was given the opportunity to use a ktm sx125 ( an adult bike. ) I rode it fine and felt comfortable on it but I had to "cheek it" a TON. The guy who owns the bike and the track recommended that I get a kx 100 but I will be growing pretty soon and don't want to grow out of it. My dilemma is should I get the kx 100 right now which fits me now, and grow out of it in a couple years when I hit my growth spurt or should I get a ktm 125 or other brand of 125 and have it be a little bit big but still rideable, and not grow out of it. I also want something my dad could maybe ride ( he currently has a kawasaki 250cc ) He is 6'3"
All help is appreciated.
Also I am mainly going to be riding on a motorcross track and a little bit of riding in the hilly wheat fields around our town. ( All private property )
