Honda Politics. They want the V5 to look unstoppable and make it look like their development of the bike is going great by making Katoh's bike a little slower. Just my opinion anyway. They wouldn't let the old 2 stroke beat their new baby, now would they? Even if this is not true, sometimes riders are just slower. It's a phenomenon in racing. Look at Ben Bostrom last year. In the Valencia test, Ben was so much faster than everyone else, but when the race practice/qualifying came, he could not figure why he wasn't near as fast as he was in preseason testing. I think Troy Corser won both of those races.
