Brian...a few things to consider between the 05 and 06. First, which style graphics do you like? The 06 is the only other CVO to have the eagle other than the SERG. The 05 has a completly different graphics style. The 06 has Brembo brakes..05 does not. 06 has the 240 rear...05 is 180. The headwork is slightly different on the 06, but the difference is insignificant, IMO. There is a little more chrome on the 06...grips, pegs, and a couple of more odds and ends. The rake is slightly different on the 06.
Those are things that immediately come to mind.
Color: Of course, I like the RED (Scarlet)...fell in love with my bike the first time I saw it, but it took me three months to finally buy it. I've seen the Orange, and I personally like the red better because of the flake color. But I am not a big orange fan...I have no orange clothing...the color just doesn't go well with my coloring. Craig's Yellow is beautiful, and with a dark tan seat, it would add the touch it needs, IMO.
Two main things would make me buy the 06 over the 05...the SE graphic and flame pin striping, and the fat rear tire. The fat rear tire makes the 06 sale for a little more, IMO.
No offense, Ed...the 05 is gorgeous too.
