    Heat

    I too ride a 14 RT and just last week coming from South Dakota temps were mid 90's and there was a lot of heat if I used highway pegs! Hadn't really noticed it before but it was not comfortable at all for any length of time! In fact on different forum there is a rider who has used some plastics to vent heat further away friend rider....
    2014 R1200RT
    Now gone 09 RT
    10xxx and going!
    living for riding,riding reason to live!

Heat management is one of the RTs' greatest benefits. The opposed boxer engine design by itself helps keeps heat down from 1923 through 2018.

    I have not ridden a K1600, so cannot comment on them, but your comment does not surprise me.

    I see you have had both the 2015 and 2017 model years. Other than color changes are there any differences from 2014 - 2018 models? I understand they did something internal in the transmissions for 2017 but I couldn't find any other changes throughout those years. Thank you for your input.

    IDK what the problem is, IMHO the OP was perfectly clear. BTW my RT is AOK re temp...YMMV. OTOH my F6B fan actually blew forward so even hot 6cyl rarely got to my legs.

    Your acronyms suck big time. English is a precise language. If you can't understand it, tough luck.

    I should not have to guess If you can't be clear in a simple sentence, too bad. I should not have to combine some obscure notion of the thread with some poor guys English to figure out the question.

    Hmmm...I'm pretty sure it just one guy so, to be precise, you should have typed "guy's" instead of the plural of "guy."

    Ok Ill chime in, I had a 12 1600gt for 2 years and 24,000 miles before trading on a 15RT, the heat from the 1600 was much greater than the RT

    Thank you, so what made you move from the GT to the RT? Also any negatives in the move?

    RT weights a lot less than the GT almost 200 pounds, easier to handle in garage
    Electronics on both bikes are pretty much the same as is handling at speed, so it came down to a weight issue
    Plus in the back of my mind were the potential maintenance costs of the 6 cylinder bike

    Man, nothing was worse than the 2005 FJR I had. OMG. I feel ZERO heat. Period. Full stop on my '13 RT. It really is the perfect touring/sport-touring motorcycle: fuel economy, mechanical simplicity, light weight. It's the best.

    2016 R1200RT, the same. 96 degree days, only heat is what I feel from the sun when I'm stopped.

    Aside from the fact that "heat" is a very subjective categorization of the issue, some complain about heat from the RTW, but I suspect they are not comparing it properly.

    I think it can be said that the R1200RTW does about as good a job as there is for *reducing* the amount of engine heat that gets to the rider.

    The water-cooling/rads take care of 35% of the cooling. The opposed cylinder positioning (in the airstream), oil, and body-panels take care of the rest. The GS has everything the same, except the body-panels. After having put several thousand miles on both in multi-day, 500 mile+ per day rides, it becomes very apparent how much the RTW body-panels make a difference to directing the heat away from the rider.

    The idea that one bike runs hotter than another is usually incorrect. The most common issue is how well the heat that every internal combustion engine generates is kept away from the rider.

    I've ridden K1600s, but not long enough to be able to speak to the flow of their heat, except that I did notice heat more on the K1600s than on my RTW. Having said that, my sense was that the level of heat I experienced from the K1600s was on par with the level from the R1200GSW.

    To me, it is about where the heat flows and the RTW is very good there. None are fun stopped in traffic, but again the RTW works best there as well because of the cylinders being out in the airstream and the shrouds directing it away from the rider. That's been my experience/observation.
