This kart is a blast. We used for training and fun. We found that my son picked up 2 seconds when we ran his regular kart after this one. There is so much more going on that really all they have to do is turn in the regular kart. The piston, ring and fuel pump have been replaced. It has a CRG chassis and 60cc Kawasaki motor. It is pretty much bullet proof. I have extra tires to go with it. Let me know and I will send you some photos. Make me an offer. I have over a $1000 in it but will take a respectable offer you pay freight. Really it is a blast!!!!
