What is the difference between F500, F440 and FMod?
F440, F500 and FMod are all basically the same. SCCA changed the road racing class name from F440 to F500 a few years back when we switched from the Kawasaki 440cc engines to the AMW and Rotax 500cc engines. FM (FMod) is the Solo II or autocross class for F500 cars. Kawasaki powered cars are still often referred to as F440s, but technically (as far as SCCA is concerned) they are all F500s.
