Very clean, runs great. It's a close to 40mph mini bike. That shoots out of the hole! These are the mini bikes that with a torgue converter off ebay for $175 and a smaller sproket cna run over 65mph. They been known to run up to 80 but you lose low end torgue. I bet it gets 80 mpg. I know one tank will last all season. I wouldn't put a 7 year old on this. It halls full grown men anywhere you want to ride it. Middlebury,IN $350 OR TRADE.
