I am looking at a new dirt bike i have barly ever ridden but i am confident and i have four wheeled, snowmobiled and jet ski. I play lots of sports and am a natural athlete. all my friends race and ride 250's both 2 and 4 strokes. I am looking at a 125 but am willing to go to a 250 as long as i dont go all out i wanna stay with a 2 stroke and i wanna keep this for a while. I will take it to a track so i am defriently getting a mx bike. I really want to stay with yamaha or my back up is kawisaki but my friend has a kx250f and blew it up twice in one week. Please help...
