This is my 40cc air cooled mini quad bike that I built. The standard engine you get in these frames are only around 4bhp so I took that out and added a tuned air cooled race engine instead which produces around 8 - 9bhp. Top speed in this video is only around 40mph but it was geared from this kart circuit. With different gearing it will go a bit faster.

Hope you enjoy the video.
