Hey guys. this question was asked before but i didnt get that many answers so here it goes...
I'm new to dirtbiking and have been out with my friend a couple times riding. I have been looking at many different bikes that could suit me. So far i have narrowed it down to either a 2 stroke 85 or another 2 stroke such as a kx 100 or sx 105 type of "fill the gap" bike. I have been looking around and like the ktm models the best because of there lightweight design and aftermarket parts. I have to pay for my own bike so i cant get a bike that i can only use for one season then outgrow. I am 5' 1-5'2 and 95 pounds (13 years old). I was wondering if i should go with a sx 85 or a sx105. remember, i cant buy a "starter" bike because i dont have enough money to buy another bike in a year. So would a 5'2 95lbs 13 year old fit the 105 or should i just go with the 85? ORRR should I wait till next season and if i grow enough buy the 125. Many Of people have told me to go with 4 strokes cr150r bikes but they are out of my budget now. So I want YOUR opinion... bikes, models, years, displacments...
Thanks a ton, Happy shredding
