We just did a lot of work on this, new carb lots of new electrical and got it all cleaned up. it’s a 125cc but it is the smaller size. Top speed is 35 with my son who weighs 200lbs so a kid that actually fits it would probably be high 30’s low 40’s. It runs well we’ve had it for close to 10 years and haven’t rode it a whole lot and it sat in our garage for a long time. Needs tires my kids burned these up on the street instantly. They all hold air but a few of them are smooth. $350 as is or $450 if I put tires on it.
