Thats probably why HD didn't use his fan fix.

Jason never claimed his fans replaced the cooling fins, but they do a damn good job of supplementing them. a proven 30 degree cylinder head temperature reduction under many conditions is a hell of a lot better than any oil cooler has ever done. those 112 CFM's are focused on the two most concentrated heat sources right where the air channels go through.

Ultra Limited, CVO Limited, and the Trike. I don't think there are any others (yet)

Man, I bet HD is really hating the fact that all of the mechanical engineers and automotive design professionals on this forums did not have a chance to critique the design (from an internet picture) before they released the new line of bikes that they just threw together without any thought. Maybe next time, internet engineers!
