The ECTA 2-cycle, 4-cycle classification structure was put in place because
that's what the scooter guys wanted. It's obviously doubles my data base of
records and makes extra work for me. My best guess is that about 95% of all
the records set are 4-cycle anyway. But the racers are happy and if works
for us.
Does the FIM make any distinction between the two?
