I have an 06 yzf 450 w/ white bro's carbon pro pipe, gps suspension (don't like), renthal sprockets/ chain, really like the bike overall, especially the power. Read alot of shootouts an articles on the 07 and cannot decide. Sounds like it has less power down low but my pipe will fit the new bike. Has anyone traded their 06 for an 07? Is the 07 noticably better?
