This photo is from the Team ProMotion
www.rideTPM.com GPMoto Series UltraLight SuperSport race. This is a mix of 300 class bikes. In this pic I'm in the lower left in 5th overall (2nd in class) and sirref is to the right in 4th overall (third in class). The three bikes at the top of the pic are the lead group. Ben and I got held up in the opening laps and they took off. The bike in second position there though started on the back row and just motored through. These little bikes are all about keeping up speed through the turns and he carries so much corner speed that his overall speed pushes him through.
Here's the video I shot using front and rear cameras.

If you have one of these you really need to track it. It is sooooo much fun.
