I don't think there's anyone here who doesn't know that given the same displacement, a motor with more cylinders will make more power.
But, Superbike racing is about allowing manfacturers to race what they sell and about coming up with appropriate rules to foster competition.
I certainly don't know if that makes him right. I mean the rules currently penalize 6s, so it's kinda hard to say 4s are superior when the rules don't allow anything else.
I think I could probably go back and quote jb from a previous Mo rant questioning his reasoning skills.
