Cylinder Heat ?

Having never owned a BMW....investigating the possibility....
When one such as I looks at a BMW Boxer he simple must ask, don't those clyinders hanging out there heat your legs up ?
Well...do they ?

Me, neither. Because they are out in the air, they tend to stay cooler than the cylinders on any motorcycle I've owned.

I've never noticed any difference, winter or summer. A friend of mine used to complain about his feet getting hot on his GS, but I never felt anything. Usually you will be moving fast enought for the air to go right by. If you're concerned and want to see for yourself, go to a dealer and take on for a test ride.

They don't heat up your legs but do protect them from the wind witch is great in summer and a little less great in summer but nothing uncomfortable. They do give you protection in side impact accidents and when you fall over.

I hear that BMW riders have far less lower leg amputations.

On a happier note, never had heat problems from them, one or two times have felt the heat from the catalytic converter, but moving feet to outsides of pegs helped.

Most folks buy into the bike as is and leave the emissions controls alone. Cut something else off if you have to but be proud of the clean engine you're going to pay a premium to buy.

No, no heat to speak of except idling in gridlock in 90 degree heat. Not good to let it idle in those conditions and heat will be evident in feeling and engine noise. The police boxers have fans on the oil coolers for this reason.

Alot of riders get rid of the cat and original exhaust. It most likely will not be a big deal on the R1200R.
On my 98 K1200RS the cat and exhaust got very hot and would take 30 or 45 minutes to cool off. It melted my left hard bag it got so hot.
The stock exhaust system IS nice and quiet though and I really like quiet. If I could have the quiet of stock and the light weight and cool of after market I would go for it. My son has carbon fiber cans on his Suzuki SV 650 and those stay very cool. You can put your hand on them after a day's spirited riding.

CATs certainly have their place but, I'm already doing my part by:

1. using two cylinders instead of eight, and I'm proud of it.
2. 50% of my driving I get 45 mpg, which is proabably twice that of my neighbors SUV. The other 50% is probably better than their SUV.
3. living 6 miles from work instead of the U.S Avg of 16 (what I found)
4. Live in a communitiy where I can walk less than 1 mile to 6 different resturaunts, 2 grocery stores, 2 drug stores, and anything else I need.

I could go on.....Of course I make up for all this when I hop on my 2-stroke !!!

Been ridin' twins for 30 yrs ( a few k's too). The jugs DO SAVE legs and other related items ...minimizing damage should you low side. Also, you can lay it on the jug and raise it rather easily! The jugs do impart some heat. Just get your leg in the oncomming air stream and compare behind and not behind jugs.....HOWEVER no problem in the summer and wonderful in the winter. Twins = Sheer riding pleasure FOR SURE!

THE jugs are very VERY strong at least on the airheads. Actual accident 1986. Buddy was riding his 1978 r100s. Drunk turned left in front of him. Buddy and Bike lived eventhough closing speed was about 50 to 60 mph!. Buddy slight concussion, minor abrasions etc. Bike, exhaust crushed to the head, ALL fins ok !, Front forks, front wheel, frame gone, bike rebuildable, took me a week, runs to this day w/o any problems! Truly incredible machines
