Hi guys, I ride a 2000 Yz 125 and my little brother sees me ride and he is itching to get on a bike. He is 8 years old, 49 1/2" tall and about 50-60 lbs. I want to get him started racing and riding young. I was thinking something like a KTM 65. I wan't something with power, yet not a pu@$y bike. I wouldn't mind a 4 stroke but I would rather have a two. Any suggestions? Thanks
