Quite true!
I was reading a story about evolution of sportbikes yesterday by Kevin cameron. It used to be that you could buy a bike, pipe it and put a jetkit or PC on it and within a few years the new version of that bike was faster stock than your "tricked out" superbike. I think that will always be the case until some do gooders get legisaltion in place to reign em in even further. But the one thing that will continue to progress is the lower weights, better suspension, better brakes, better electronics, tires, ergonomics etc. Cameron labeled the story the golden age of motorcycling. Perfect title!
