Default Liquid cooling coming soon?

So, I found this video

2012 Harley-Davidson patents cylinder head liquid cooling system for future engines

http://www.youtube.com/watch?v=H_Wh2zha8ug


and

What do you think? I think Im glad I got my bike in 2004, before all the massive electronic junk started to pour out...


Harley, just please NO, stop adding junk to our bikes...

Isn't the V-rod already liquid cooled? I know many people don't like the fuel injection and the other goodies, that M/C manufacturers are adding, not by choice, but its that they are being forced to by the EPA to reduce emissions

it's not a matter of adding junk, H.D. has to please the E.P.A. This is as much about noise control as anything else and it is inevitable. Check the oil cooled heads on the XR1200.

glad then that I have a older bike, would never buy a V-Rod ... this is the end of the brand for me... if I wanted something like the V-Rod, I would go to a japanese brand

Harley should lobby this, or pull out of the country and start making stuff outside, far from the EPA jurisdiction. This is just another nail in the coffin.

Also, this liquid cooled thingy on the video looks half assed attempt at most (check comments on the kneeslider page for justification)

well, Harley, good riddance, you lost another customer...

There's another thread on this - in which I mentioned that I've got a bud who was working with Harley (as an engineer) a few years ago when they were rigourously testing these water-cooled head designs... yes, it's coming, but only Harley knows for sure when.

As a side note these should give better or more even cooling allowing for some additional horsepower, heaven forbid we should get more of that!

It's gonna happen whether anyone likes it or not and HD wouldn't be able to do a thing about it since the EPA has become so stringent on emissions. Nor would it matter if HD went elsewhere just to make their bikes since EPA would still say that they MUST comply with EPA emissions requirements, or their bikes won't be sold within the states.

If done right with quality parts and it doesn't fluff up the MSRP too much I'm all for it.
Wouldn't liquid looling make the engine last longer? Plus you get a temp guage
Liquid cooling is a very simple system so I don't see how it would add much complexity. If you can work on the cooling system in a 69 Chevelle you can work on the cooling system on a bike. I've had a few older bikes with radiators and they never gave me a problem.
Think about it, the engine would warm up better when it's cold and cool off better when it's hot.
It seems to me the only down side is it could look ugly and THAT's the biggest challenge.
