PLEASE DO NOT BUY! I've purchased one of these for my 4 year old. Second set of complete brake sets. They lose power and don't bite. I've tried everything. The second set lasted about 3 weeks before repeating again. It was replaced by the place I bought the bike from and still the same. Very dangerous bike. Our CRF is still a tank after 2.5 years of ownership. Save your money and buy a Japanese brand bike.
