I have noticed some excess heat on my left foot (I don't always notice it depending on my footwear at the time). I expected there to be some heat from this big engine and adjusted my expectations. Big engine == heat (and more so on hot days). So far it's never been uncomfortable, just noticeable. I suspect in the cooler months, it will be welcome

 

It's been an unsually cool and wet spring up here in the north east, but I have felt zero heat anywhere. I do ride ATGATT (all the gear, all the time), i.e. riding boots, jeans under the Aerostich Roadcrafter 1 or 2 piece suit. When I was in Virginia, temps were around 29C, (about 84F) and I felt no heat.

 

In the summer, I wear a thinner riding boot... I wonder if I put my winter boots on if I'll feel anything. Are you wearing thick booth Gadget?

 

I noticed some heat on my left foot when I took a test ride on a GT a couple of weeks ago. It wasn't a lot of heat but I did notice it. I was wearing TCX Airtec boots which allow some air flow through Goretex panels, so they probably allow more heat to get through than other boots. Incidentally I wear those same boots when riding my GS and although I rarely feel heat directly from the engine on the GS I do feel some on my left heel where the exaust pipe rises behind the left foot peg. I didn't have the impression that the heat from the K16 would be any more of a problem than the heat from the GS is, but it is one of the things I'll pay attention to when I get a chance to take a longer ride. Incidentally, it was around 65 degrees F when I took that test ride.

 

well i shouldnt of but i wore tennis shoes and jeans, and i felt no heat. I do try atgatt but...... I am getting a new first gear suit when i get the gtl (next summer lol) its a tpg, nice piece, and has pants and coat. i have first gear summer wear, which is great in the summer, you wear shorts and t shirt, then the gear, when its reaaaaly hot, you get someone to spray you with the hose, its like ac for an hour. just saying...

 

I've noted a bit of heat on the left foot, primarily in slow commuting traffic at 90F+ temps. Not uncomfortable, but coming from K12LTs which had zero heat issues on the feet, it was a surprise -- although it probably shouldn't have been, given the cat and the pipes *right* next to the toes, under the cover plate.

At some point I'll lay down under the bike to see whether there's an obvious plate to locate a diverting panel.

 

No heat here, 90 degree day, shorts and sneakers!!

 

This may be a case where heat wrap could help?

This would also keep the oil cooler as the oil pan runs between the exhaust pipes. Think about all the radiant energy given off by the catalytic converters when the bike comes to a stop, or when you shut off the bike after a ride.

Shouldn't make much difference -- this a is a dry-sump engine. The oil is mostly sitting up in the reservoir behind the tranny/clutch, or circulating arounf the engine. The "sump" here is not an oil storage location, it's a transient area from which the oil is constantly being removed from the engine for return to the reservoir.

 

I have ridden the Demo for a total of 6 hrs so far with TCX toruing boots and feel no heat at all and 1 day it was 88 deg for 2+ hr ride... Wearing jeans also and no heat felt....

 

I wonder if it's from the oil filter ? It's right there by your boot.

 

If you wanna experience heat take a spin on the Honda ST1300. The one I sold would cook you in traffic. The K1600 GT heat is not bad at all.

Rode the Gateway BMW demo GTL today, and noticed quite a bit of heat on my left foot up near the toe (91 degree ambient air temererature today). I looked, and the oil filter is RIGHT THERE by the end of the shifter. My boot was pretty close to that hot oil filter during the ride.

I might have to look in to some kind of heat shield for the inside of my left boot.

I'm sure at some point, someone will come up with a remote mount so we can move the filter.

Heat wrap is great, as long as every time you start the bike, you run it so as to get the wrap hot enough to evaporate out all of the moisture it has gotten while not running. if not, its a quick way to rust your pipes.

you could send the header with the cat welded to it out to the ceramic coater and get the whole thing ceramic coated on the outside. you can pick pretty much any color you want. im not sure but i think the cat is welded to the header pipe. if not, you could get the ceramic coat on the inside and out.

you could fashion a piece of .030" aluminum in a semicircle and mount that on the oil filter with a band/speed clamp just put a step in the panel in the middle so it only contacts at the point the metal hits the filter. remember they have an oil cooler for a reason, so i would think we wouldnt want to wrap an oil filter since that might keep the heat up, cooking the oil.

More often than not, a company only puts an oil cooler on a bike if it needs it to keep the oil cool. It is the cost account that causes that as well, dont believe me, look at the high mounted taillight.

 

The built in foot warmer is connected to the headlight. Turn to the left and the left foot warms up turn to the right and the right foot warms up..

 

I was riding on Tuesday here in OH when it was in the low 90's, and I definitely felt the heat on my left calf/foot. I mean serious heat, reminded my of the heat from my Harley, actually caught me by surprise, I wasn't expecting this.

That said, I was wearing tennis shoes at the time, so that didn't help!

I found that by putting my feet up on the passenger pegs they were in the wind and cooled off nicely at highway speeds.

 

As I wrote earlier in the demo ride opinion, my left foot was cooking to a medium rare. It was honestly the only fault I found on my demo ride and it sure was not bad enough to change my opinion of the bike.

 

Got to put 160 miles on the bike yesterday :k16:

There is definitely heat on the left foot that is noticeable around 85 deg F and above. It's not as bad as a lot of bikes I've ridden in the past, but it's there.

I've got my own theory and I don't think it's the oil filter. Here's a shot of the oil filter placement.



The heat actually is not so much centered on the foot, but between the shin and below the knee. This of course could be due to the boot providing shielding, but I actually think its the location of the header pipes which is the culprit.

Here are two pictures of the left and right sides of the bike. Notice how the header on the left side is barely a 1/4" from the side, whereas the right side outer header pipe is buried (you can't even see it in this picture). I think there is a lot more extremely hot air coming off the left side header, which flows over the leg.

 

I complained earlier from the heat coming from the left side on my foot... I ride most of time wearing tennis shoes!!
last time i went for a ride i was obliged to wear my ridding boots to prevent the excess heat which i couldnt tolerate!!

 

Call me crazy, but I don't think that BMW's engineers did there development rides wearing tennis shoes.

 

If we determine that it is the exhaust header, I wonder if this product would look good, protect from the heat & not rust the pipe?

summing up

ok so there seems to be a consensus about heat on the left foot. Some riders seem to tolerate it better than others, or maybe they simply live in coolers areas. Tennis shoes appear to be particularly sensitive to the heat.

Assuming the heat source is the pipes, do you think there will be any difference between GT and GTL, given the slightly different footpeg positions ? or is this irrelevant?

This seems to be one of a few glitches you, beta testers, are reporting. Do you think this is something BMW ought to correct in future model years... or there is no clear solution to this problem?

Thanks

If you read it on the internet, it must be true!! :lol2:Consensus? C'mon.. a few guys reporting some heat on their left foot, others reporting none. One reporting feeling heat when riding in Saudi Arabia in tennis shoes.. wait till temps hit 40Celsius over there.

I've felt zero heat.. so add that to the "consensus". The moto press has had zero issues with heat, even at the press intro in South Africa where temps were in the 30C.

"assuming" it's heat from the headers.. makes it a "problem"? Have you even ridden this bike to determine if this is a "problem"..

If someone determines that the heat they feel is indeed from the header, maybe that person ought to look for a different bike.

FWIW, I have not felt any heat on either GT or GTL. I now own a GTL and ride it daily in city traffic; no heat "problem" of any kind for me. But I don't ride in shorts and flip flops.

 

Before ever even noticing this thread, I was out for a long ride on my new GT (riding in boots) and did notice some heat on my left foot. But I'm gonna take the middle ground here. It was over 90 degrees out and I was in city traffic, and the heat was in no way uncomfortable. I just noticed that there was some engine heat that could be felt on the left but none on the right. I conclude that it is correct to say that the K1600 does produce some heat on the left in warm weather, but I would in no way call it a problem or in any way in need of a fix.

 

Ah...

+1: felt it same as mentioned below (city traffic, in Sidi boots) on left foot, both on the GTL demo, and now on mine (temps 90+ on demo, 85-90 yesterday). I concur that it's not a "problem," merely something to mention.

 

I had a second test ride on a GT today. I rode for over an hour at around 45 to 65 mph. The temperature was around 75 F. I had recently read this thread so I was paying particular attention to see if I felt any heat. I did notice a that my left foot was slightly warmer than my right, but if I hadn't been looking for it I don't think I would have noticed it. In fact, I forgot about it by the end of the ride.

Someone above asked if there might be a difference between the GT and GTL due to their different foot peg locations. That thought had also occurred to me today as I was riding and was trying to understand why some people were reporting heat and others were not. Maybe it would help if you all could mention what type of bike you were riding, along with your descriptions of how much heat you felt?

 

I took care to notice the amount of heat on my feet on the ride home today on my Goldwing and even though it was 66 degrees I could feel a fair amount of it on both feet. Of course the GW has a flat 6 with the cylinders a little above and in front of your feet so it's not much of a surprise. I'm pretty sure it has more than the GTL does.

 

The ride home today was cooler (79 deg) than the 89 deg on Thursday. Did not notice any heating of the left foot at all.

My thinking is that it's noticeable around 90 deg, but only because the left foot is heated so much more than the right. That's my theory and I'm sticking to it.

 

In that the exhaust system is symmetrical,equal temperature should be radiating the same for both sides.
I believe that the extra heat is the result of the drive shaft being on the left side and it is radiating heat that is part and parcel of the entire engine/drive line being warm.
How is that for a theory for someone that is #750 and waiting?

Actually it's not. Take a look at my earlier post with pictures. The left header is much closer to the left foot, than the right (which is somewhat buried).

 

sfoster, point taken.
