This is a racing series I have followed for a few years. Their most popular machines are the XR100 and the KX65, and they rip them around local go kart tracks at full tilt. The first video is a great little promo/trailer of the events and the second video is some good onboard ride footage, albeit not the most exciting of races.
A few buddies and myself have acquired a KX65 but have not made it out to an event yet. Maybe next season we will be track ready and out there rubbing elbows with the best of em!
