As for FIM they allow Ducati about 1200 cc vs the 1000 I4 in WSBK, and with MotoGP, you haven't read the rules very closely have you? The FIM has a weight penality based on the number of cylinders, a performance based handycap.

And the reason they have these rules in the first place, is that with more cylinders you can make more hp for a given displacement. A 6 will make more power than a 4, 8 more than 6, 12 more than 8. And you can see the same progression, and then rules to limit performance in F1.

That's true and I considered an edit. Regardless, it's not a DOUBLE penalty. Besides, everyone should race with the best engine package technologically available. If it is an I4 great but if it isn't then change your package, don't change the rules to suit your 100+ year old engine set up. As far as limiting performance, I totally understand that and they can do that but let's not penalize the teams that are smart enough to arrange those cylinders in a way that makes the most power. For example, if the cylinder number limit is 8, an advantage shouldn't be given teams that CHOOSE to build an engine with those cylinders in a line, or radial, or a v, or boxer style, etc. Hey do your testing and run what you brung!
