K1600 Overheating problem

I was on the Dragon Monday. I passed a few Harleys and cars.

I passed a Lincoln SUV on a tight turn. I had been turning 7 or 8k for a bit when it got into the red.

I know I pull a 325 lb trailer but surely BMW could have built a cooling system to sustain 8k at higher altitudes pulling a trailer.

For what these things cost such a super disappointment. I know my friends agree with me./

Paul,
I didn't hear that any of the 50 K1600 that ripped up and down the Dragon last month had overheating, so I surmise that pulling the trailer is what put you over.

Just curious, do you have a Nav V or VI that shows the max temp reached?

That is the issue! When the temp creeps up for whatever reason gear up! Speaking from experience as far back as my LT with a smaller engine and much larger cooling system.

And if they put in an even larger radiator, then folks would complain about how ugly it is.

The radiator has enough capacity to keep the bike cool, although you can push things right up to the limit. Like running extended periods at low speeds and high rpms. Or towing a trailer...

The biggest thing with the K16 radiator is to make sure it stays clean so that you get maximum airflow.

But if you're really pushing the limits, then yes, the bike can get hot...

Some people see the gas tank as half empty. Some see it as half full.
All I care is that I know where the next tankful is coming from...

Really? The K1600 was not designed to pull a trailer. Some do it and pull it off but I'm sure they are not riding as hard as was done.

Not sure of any motorcycle designed for those RPM's pulling a trailer, good luck finding that bike. Maybe a Boss Hoss V8?

I pulled 1100 lbs a thousand miles from L.A. up to Portland, including crossing the Grapevine in southern California and the Cascade/Siskiyou Mountains in northern California and southern Oregon.

To be fair, I did have to rebalance the load to add a bit more tongue weight, but after that it pulled just fine and the bike never overheated once, including when running well above the posted limits...

Gradients, altitude, lugging hard (your trailer) & low speeds are the bugbear with many a K16 tipping into the red zone, which is well documented on here.

Search is your friend, so it's simple to check out the experiences of others .......... cleaning rads, burping the coolant & more recently an owner experimenting with adding a second fan to the system, which seems the way to go IMHO.

Paul, I recommend a good clean out of your rad. You will enjoy a significant difference. How did you manage to pass all those bikes and the Lincoln pulling a trailer on the Dragon?

Ken, I know you are a long distance traveller; but pulling your own pneumatic tire changer and extra rims and tires behind you when you travel is a bit much, no?
