Is that why I have to explain the difference between SBK, SS, and SStk standards to you? or AMA vs BSB?
The margin of victory goes up with the "openess" of the formula, not the advancement. If everyone drove a McLaren MP, F1 would be advanced, and the racing would be relatively close. If I wrote an unlimited formula for stock production bikes (5,000 units produced) on stock road-legal tires, the margins between the different types of bikes would be enormous even though they are just low-tech stock nails.
Advancement and margin of victory are not related. You just read the Paolo Flammini article where he said that the manufacturers sell very different SBKs, and they need extensive modification to reach parity.
I also don't care that much about margin of victory, but if the racing is boring, the formula had better be open. Open formulas usually attract a wide variety of participants. The GP formula is not open, and MotoGP has only 3 factories. The situation cannot be denied, nor can it be blamed on casual fans, especially since fuel-limiting and naturally-aspirated displacement rules killed Group C in about 18 months. Motorcycles are not sports car prototypes, but the fundamentals of ICE powertrain are basically the same.
