ok so when i was younger my dad bought me a dirtbike it was a tiny little thing but i had so much fun on it. well my dad had to sell it because he never really had time to take me well now that I'm 16 and I can go to the mountains or off roading by myself or with friends, I want my dirt bike back but I'm not quite sure which bike is right for me. I'm still small 5'2'' 105 Lbs but I want a bike that can go on trails and still have speed. any help?
