CCS, CMRA, MoM, AFM, WSMC, etc are running Formula 40 classes, and most of the clubs run two F40 classes.

As of 2010 there are 120 licensed MRA racers who are 40 or older, 73 experts and 47 novices. This class would be a great addition to our club because we already have a large number of eligible riders, and all of them can run their current bike. I’m proposing two classes, F40 GTO and F40 GTU. They would be scored separately and gridded in the same time slot, GTO starting in front, GTU second wave.
