Have you checked reliability, maintenance intervals, and the like? When was the last time you saw engines grenading like they used to do in the 80's? Heck, MY lap times keep getting faster on virtually stock bikes. THe brakes work through the entire session, no fade. The (titanium) valve adjustment interval on my 06 R6 ( yeah, yeah, I know it only turns 16K RPM) is 24,000 miles!!
