Harley Davidson Does Hold Patents For Water-Cooled Twin-Cam Engine!

Everyone keeps talking about Harley Davidson making the move to water cooling, but there's nothing like a patent to show us what they're up to. Here are Harley Davidson's plans to water cool the heads on their touring models by hiding the cooling system within the leg shield portions of the fairing.

H-D V-TWIN WITH WATER COOLED HEADS
The cooling system, consists of 2 radiators, fans and hoses hidden within the fairing. A water pump is centrally located at the bottom front center of the frame. The water passages within the heads are rather basic, a simple loop that carries the coolant more or less along the exhaust passages and wraps back around the valves before returning to the radiator.

H-D V-TWIN WATER COOLING SYSTEM
Although the patent shows and describes the cooling system installed on a Harley touring bike, the patent states:

Please note the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of being used in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
.. which basically means it can show up arranged to work on any of the bikes in Harley's lineup.

The entire cooling system seems pretty well worked out and ready for production which was recently unveiled in some of the 2014 models. Read more about it in an upcoming issue of American Iron Magazine.
