I saw an ad in AIM recently for the Oil bud oil cooler. It's pricey @ $600+ but says it is guaranteed to lower oil temps 35*.
Fits underneath the engine / tranny.
Looks like a quality setup from what I have seen online. I have no experience with it.

The Ultracool is well, ultra cool. Seems like it wouldn't really be that hard to install a fan set up on the Jagg or HD coolers, say behind the cooler. Might be worth looking into. Would need to be waterproof but they make fan motors that are sealed. My bet is that any additional Jagg or HD cooling radiators will be sufficient for most folks, but the parade groups might like the fan. My bet is that it won't be long before HD does a water cooled motor.

It isn't so much the engine parts that fail under extreme heat, it's the oil that fails. And when the oil quits doing its job, bad things can happen............
.....Some times, this is the same guy that's always putting the newest 103" or 110" motor in his ride for 'no reason' too.

Anyway, you got me thinking about this and I know most of you are gonna think, "Whats this guys problem?" but, trying to play devils advocate here and its a really slow day at work
:If its rare that catastrophic events (e.g. bearing failure, piston ring snaps, etc.) are directly resulted from overheated oil, but rather a sustained degredation of the oil's cooling and lubrication properties leading to increasing engine damage. Then, would just increasing the oil change frequency work just as well as installing an oil cooler? I know it probably impossible to say but this thread has made me at least make sure I do oil changes more often if I ride in the heat (if I dont get an oil cooler)

Grendel4 - thanks for the write up. Makes sense and is good to know.

Like I said earlier, it isn't normally the engine itself that fails, it's the oil and sometimes the seals.
It's not like, if your engine oil over heats, your bike engine suddenly blows up. Harley engines are tougher than an old Army boot. Beyond tough. It's the Chinese water torture, the drip, drip, drip, little by little damage that adds up over a period of time.
We all know that you're brain-dead if you blow your radiator and keep driving your car. Bad things like blown head gaskets from the heat warpng the head tend to happen. Not so much on a Harley. Like I said, Harley motors are beyond tough.
But over a period of time, your engine just doesn't produce the power it once did. Can't figure out why. It's just a 'Harley' afterall, right? It starts puking oil out of places that it shouldn't, but it's just a Harley, right?
Wrong. Something is causing that. And sometimes the culprit is the cumulative effects of constantly over-heating your engine oil. Sometimes. Sometimes -- Not.
I'm not saying that an oil cooler is mandatory for everybody. No way. Not my place to say that. People who live in temperate climates and rarely run their bikes hard in really hot weather proably don't have the need as much as someone who lives in the South or Southwest and their bike routinely sees hot weather in the high 90's and asphalt temperatures over 150*.
I'm also not saying that we should all run out and drop $500 on the best oil cooler on the market. I'm just saying that, if you're thinking about an oil cooler................ That should tell you something.

Oh yea, I forgot about the VRod, its water cooled. Like my Kawasaki ZX12R, it probably never overheats. I rode the Kawasaki through Vegas several years ago, it was 111 degrees and the temp was in the normal zone the whole time. Me, I just about died! Anyway, I ordered the Jagg 10 row cooler, do I need it, probably not but I like the idea of having it, gotta lower the temp somewhat which is a good thing.
