My cousin just turned 12 and my uncle bought him this sweet 50cc go kart. The thing is freakin awesome. It's like a little smalle cart with wheels and a 50cc engine. The thing can go pretty fast. I think it can go about 35 miles per hour? It's pretty good for the age thats behind the wheel. 50cc go karts are great gifts for kids around that age. Just gotta remember to wear a helmet.
