I've owned both a '03 and '05. I think part of the problem is magazines poison the public’s mind with the crude they print. Every magazine said the '03 was the pro level bike only and was a monster. I had the '03 up until last November and really liked the bike and guess what I'm not a pro level rider, not even in my dreams. The '05 IMHO has plenty of power and the way the two bikes deliver power is not all that different between the two. Anyway who cares the ‘06s are right around the corner ..
