Something big and blue followed me home this afternoon. I went with the stock '04 450F. Immediately ordered an hour meter, ProTaper SE bars, stainless oil filter. Got home, rode the bike around my play track and I'm pleased. It's smoother than I expected, feels good, lots of power but very controllable, and so on. Maybe because it's MY bike, but I felt more comfortable on it than I did on the '06 I tested. Gonna spend the rest of the week breaking it in and getting used to it, then hopefully off to the track Sunday. Thanks much for the advice.
