Well, i've always been in to fast things with 2 or more wheels, and I rode my friends 02 yz125 yesterday(first time on any bike), and I was in love....But I'm wondering if I should start with something different? im 14, 5'11", 155 lbs...Im not too very strong, but I could hold up the yz125 pretty easily..If I get one, it will more than likely be new so suggestions for new ones please...Thanks
