Bought this new for Son who grew out of it too fast. Only used a couple of summers before it was too small. Bike has been sitting in garage taking up space since then. Fully automatic with electric start. Utilizes Honda motor. Just replaced rear innertube.I honestly don't recall how big motor is and it doesn't say on title. It is smaller so I know it's not a 140cc. I have only ran non-ethanol based gas. Open to offers.
