Johnnie, Have one of your 60s racer buddies show you the rule and records book... You will not see a million
classes.
I was one of the people involved that was affected by minimums that seemed arbitrary at the time. The year after my son went 200.0something exit speed on a normally aspirated gas 1000 the minimum was set to 205. That was the first time a gas 1000 had touched the mark. A couple of years before a fuel (N20) 1000 went 206 to get in the club...
I argued the point, I was a club member, but I did not prevail. So I made more changes to the fairings and we worked on rider position (thanks Pork Pie on both) and Rob went 208.959 and got in the club... Special Construction then went to closed tails and all of the APS records went up... but not the minimums.
With that said, if you look, most of the minimums are in new classes and streamliners, not long time traditional classes, fewer in cars than bikes. But the Club reviews minimums every 5 years, and you can petition the club to reconsider a minimum that you think is arbitrarily high, be sure to do a lot of research on records from the past and present.
The FIA and FIM numbers and classes controversy is not new... options to change the bylaws will be presented to the membership and with any luck we will decide what needs to be done.
It is not supposed to be easy
