The trouble with motorcycle racing in any form is, the riders are not the organisers and the organisers are not the riders. It builds inertia into the system, so long before a new idea is up and running, the opportunity is long gone. Theoretically, the kids in our local club could turn their bikes into Super-Motards and ride on the bitumen instead of MX, - it is never going to happen. As soon as you get enough entries to make a race, the next fad arrives - soon it will be Enduro.
