The debate has been rumbling under the surface for some time, but at Jerez it finally burst to the surface. It emerged that Marco Simoncelli and Valentino Rossi had submitted an informal proposal to the Safety Commission to examine having a combined minimum weight for both bike and rider in MotoGP, just as there currently is in the 125cc class. Their argument was that lighter riders had an unfair advantage, and that by setting a minimum weight, the larger riders would have a better chance of competing.
The main advantage, it was said, was one of fuel consumption, especially since the introduction of the 800cc bikes, which also saw the fuel limit reduced to just 21 liters. Nicky Hayden related that while he was at Honda, his was forced to run a much leaner setup than his erstwhile teammate, Dani Pedrosa. Rossi agreed with Hayden's assessment, but admitted that taller riders did have more leverage over the machines.
