Here is a clip of Bill Riding and then racing his DAX KTMC 50cc 9hp with shift kit and yes... Using regular road bike chain.. This is the limited Class 8-9hp. The bike that passed is a guy using what I was told is a GX160cc. Remember.. This is a HP class and not a Displacement class.. Enjoy the clip.. Not sure what happened at 7 mins.. Yikes !! Bill told me he is bruised but doing ok.. Wear those shoulder pads next time Bill !! Enjoy the clip.. Enjoy the ride..
