World Superbikes makes AMA look like Amateurs even if the Bostrom brothers and Anthony Gobert are pretty good riders...but the bikes are a little bit better in the international series.

However the MotoGP riders make World Superbikes look like an Amateur sport...and this year it's better.

The top riders are now riding 1000cc, 220hp, 4 stroke prototype motorcycles with even more insane acceleration than the 2 stroke 500cc bikes had. So far in pre season testing, Valentino Rossi has gone as much as 3 seconds a lap quicker this year on the new V5 Honda RCV211 than last year on his winning 2 stroke.

Edit: It's really a shame that the US can't get a round of international racing because of the safety regulations.
I guess the injuries and deaths on concrete walls are a bit much for riders to handle.
You'd think there'd be at least one track up to international standards in the US, wouldn't you?
