I have recorded historical data for the purpose of comparing fastest "race" lap times between, MotoGP, WSB, FIM SS, and AMA superbike and superstock racing fastest race lap times,
I broke it down like this, brno being the most recent race for ALL categories, then Laguna Seca as AMA does not race internationally but MotoGP was here in july so you can compare times figuratively....
the way it looks is the fastest WSB riders could compete somewhere between mid pack and back of the motoGP riders... the fastest WSS riders would only be seconds off the slowest MotoGP riders and mid pack amongst WSB riders...
as for AMA, now get this, for a almost virtually stock bike, AMA superstock, the fastest riders will be somewhere around the back compared to MotoGP riders, the fastest AMA superbike riders will be somewhere around the back and midpack of MotoGP riders!!! and the fastest AMA superstock riders are somewhere between the lead and midpack compared to the AMA superbike riders....
quite the eye opener when you consider that FIM supersport bikes are only 6 seconds off lead pace compared to MotoGP and a virtually stock GSXR 1000 running a street legal tire can hang with the slowest MotoGP bikes!!!
