I bet in another 20 years they will be running 500cc bikes for the same reason they are going down to 800cc in MotoGP. It isn't to make them go faster, it's to make them go slower. Maybe if the GMP knew how to read, he would have read that the 1000cc bikes are too powerful for most tracks, and are therefore unsafe. The tire explosions at Daytona a few years ago pretty much told us that. It's the same reason NASCAR got restrictor plates for large tracks. They are going too fast and are too powerful for safety. Going to 800cc effectively, and temporarily, slows them down to a controllable level.....for now. It doesn't take a genius, or a GMP, to know that 800cc will only be a temporary level. At some point in the future, they will lower the displacement again, or restrict the intake size, or use other methods to slow the bikes down. Change was around the corner about 3 years ago. I'm glad this guy finally saw it.
