2012 HARLEY-DAVIDSON LINEUP TO BREAK TRADITION WITH WATER-COOLED ENGINES-- Harley-Davidson's notoriously nostalgic, 108 year practice of building only air-cooled engines (with the exception, of course, of the V-Rod Night Rod Special and V-Rod Muscle) is about to come to a screeching halt. Thanks to certification documents leaked by the EPA and California Air Resources Board, all engines in the 2012 Harley-Davidson lineup will feature a radiator discreetly wedged between each model's downtubes.

A Harley-Davidson representative reluctantly admitted that the change was coming when confronted with the allegation. "For over a century, our bikes have exuded a singular feel and an unmistakable exhaust note," the spokesperson said during a phone interview, "but toughening emissions regulations and practical considerations have forced us to modernize our powerplants."

The rep suggested that the benefits were not limited to clean air; the new liquid-cooled engines produce up to 35 percent more horsepower, and run considerably cooler than their predecessors-- with a reduction in the signature potato-potato exhaust volume. The radiators, manufactured in Japan by Denso, are purpose built for the H-D application, and feature a similar design to the slim units found on Honda's Fury chopper. All models will feature traditional placement except the XR1200X, which will incorporate a side-mounted radiator. Rumors that the V-Rod will be discontinued due to "redundancy" have not yet been confirmed.

"The time has come," the rep told me, "and our valued customers will soon see that Harley-Davidson is committed to embracing a cleaner and greener future."

I don't know what to say about Harley, but after owning a water cooled suzuki I do wish my Vic was water cooled. I am a believer that the ability to control the operating temperatures in any engine results in tighter tolerances and longer life of the engine:rolleyes:

Yeah...I'm going to my first ever non-liquid cooled engine here once the financing is approved (and it should be). Thankfully, we never get above the 80s much here in MN. lol

I call BS. ALthough I'm sure it's gonna happen eventually, it sure as heck isn't going to happen in the 2012 model year.
Happens every year....

If you doubt it, just read the last paragraph to see that it's just meant to fire up people who are die-hard harley fans that don't understand anything.

Changes the exhaust loudness because of adding radiator? lol...

Current Harley's make less noise than a mouse fart...better add that water cooling system, so that it can make less noise than an ant fart.

I think all agree that is BS. We have been hearing this for years with HD and it will never happen as long as Willy G is alive....

They will install oil coolers on all their bikes before that happens.

Yes it was interesting. However if you listen again he talks about the advantage of oil cooling over antifreeze in colder climates. I think that all of polaris snowmobiles run in cold climates and they are 100% Antifreeze cooled. All of the Polaris ATV's that are liquid cooled are Antifreeze. All of the Polaris commercial (military vehicles) that are liquid cooled are Antifreeze. He has a nice sales pitch, but in MY opinion the only reason Polaris uses oil cooling in because they are trying to ATTRACT the Harley group. It is smart on their part because if they are going to make a significant dent in the amount of cruisers sold it is the harley guys then need to bring into the polaris stable. Don't get me wrong, I think the oil cooling on the Vics are head and sholders above the air only cooling of the competition. But there is a reason all of the car industry ect use antifreeze and a fan. You can regulate (within reason not only the maximum temperature) but also the minimum temperature. That enables you to control the tolerance of all of the engine parts which in return all other items being equal will give you a cleaner more efficient longer lasting engine. LOVE my VIC, but if they had a fan controlled radiator with antifreeze option that would be the way I would go.cheers

I had a liquid cooled Yamaha FZ6 before, and the rest of my bikes were air cooled. While liquid cooling is probably better for the engine, it wasn't good for me. Every time that fan kicked in at a stoplight, it totally roasted me. For me, the liquid cooled "modern" bike was way hotter than my Warrior, and my new XR seems even better.
