Google translation does a pretty good job.

Honestly all this DOHC talk doesn't really excite me. I'm about a week away from pulling the trigger on a new 2010 and unless for 2011 there are some big new features aside from some HP and Torque changes I'm going to stick with going for a SOHC version.

The current model is really a cam within head - AKA: Cam-In-Head.. camshafts are located below the top of the valves. You can call it a CIH (which IIRC is also some sort of computer acronym.. or gooberment agency of some ilk.. or is it a sexually transmitted disease..?)

[NerdRider]

Thanks. I stand corrected.

Still what does the DOHC that everyone is excited about bring aside from Hp/Torque? e.g. Is there a reason to hold off on buying a 2011?

Oh yeah - I did predict this about ummm.. at least back in April, perhaps a bit earlier. My BMW source was on the money..

They will have to do better as far as a performance gain than what I am reading about to make the dual cam a big deal for me. Of course if I just happened in 2011 to be looking for a R1200R then I might log on here feeling a bit superior. Otherwise it will (might) just be a nice cost cutting device for those looking for a good used R1200R.
I don't know that I would like adjusting valves with shims. I am an old guy and am used to adjusting tappets.

88 ft-lbs of torque (DOHC) will move 750 lbs the same way that 85 (High Cam) will move 725 lbs (Wet R1200R + rider + light luggage), each ft-lb is worth about 8 lb in weight on the R1200R. Air temperature, fuel quality and any number of things could swing either engine towards feeling better on any given day based on the published numbers.

If any slight incremental difference (power. fuel metering, etc) drives anyone towards the 2011 R1200R, then they will sure be mad at themselves when the inevitable significant DOHC power increase comes in a year or 2 after the initial DOHC R1200R.

+1 - it's basically the same engine as the HP2, which has significantly more power then our bikes or the new DOHC in the "normal" bikes.

Note that the article is from December 8, 2009.

Slightly related to the above discussion: I was in my local BMW dealership this week and perused the BMW Motorad magazine that had an article by the head of boxer development who opined that the power/emission equation had pretty much reached its limit for an air cooled boxer and there was a photo of a water-cooled boxer (may have been Photoshopped) to show the future of our rides. Seeing a water jacket around our beloved fins made me cringe.

Personally the machine I have (2007) has more than enough power to get me out of most trouble and way more than I need to get into big trouble. I probably have enough power and enough life in the engine and in me to get me to the end of my riding days or to the end of any kind of fuel that I can afford to put in it, as our world winds down the helluva cheap oil fiesta we've enjoyed for the last 100 years. Party on...

.the guy who owned this machine probably said something similar

What they miss in these sort of articles is that the oilhead and hexhead engines are NOT "air cooled" - the fins on the cylinders and heads do next to nothing. They're liquid cooled - using oil as the heat transfer medium. The hexhead has a completely seperate oil circuit, with it's own oil pump for the cooling function. If you doubt that this is what's cooling the engine, block off the oil radiator and go for a ride. You can expect to see the temperature go through the roof in very short order.

Magazines need some sort of content to fill pages - it doesn't have to be quality content, hell, I've written for enough of them to know that..

Whenever BMW comes out with a new model, especially one with a new engine, the prudent buyer will wait at least a year or two for the bugs to be worked out. The timing to buy a new R1200R Hex head is excellent at this time as it has an excellent track record. Overall it has proven to be a much better engine than the previous oilhead series. Buying a new overhead cam engine would be risky in early series production if BMW past history is to be considered. God knows I love BMWs, and their engines in particular, but BMW has a long track record of teething problems with new designs. One of my favorite stories is from WWII. BMW was building engines for the Luftwaffe and their radial engine was not reliable. Auto Union was making engines proving to be much more reliable and the Luftwaffe ordered a particular Auto Union engineer to go over to BMW and help them fix the problem. BMW managers did not want to let a competitor into their facilities. Hermann Goering himself called and explained that the engines were vital to the German war effort and if the Auto Union guy was not allowed full and immediate access, the whole BMW management staff would find themselves in a concentration camp. The Auto Union guy was admitted forthwith and very quickly helped BMW solve the problem. If anyone thinks this story is apocryphal let me know and I will cite the source, name the names of all concerned, give you the time and date, and I believe even tell you which concentration camp was mentioned in the phone call.

As far as Don's point that our engines are liquid cooled rather than air cooled, his own example illustrates that air, flowing through the oil cooler, is an essential element of the cooling system. Oil, with its relatively low specific heat, is really not a very effective cooling medium compared to water. Meaning oil does not as efficiently absorb heat nor hold as much of it compared to water. The combination of oil with air is what cools our bikes. So more correctly we should say hexheads are oil/air cooled engines. If I am not mistaken, the company that developed and perfected this approach in modern motorcycles was Suzuki. No matter the nomenclature, this is a highly effective cooling system that saves weight and complexity.

Couldn’t have said it better!





This model bike R/75-5 was ridden by this old Gentleman. At the time I was on my second R1100S. He came over to me to admire my bike. Money was the factor why he was still ridding his old bike. He asks me if he could join me and my ridding buddies for the day.
Once we road off it was apparent to me that the old fella could ride very well. Apart from me on my BM there was an array of other bikes from Japanese 1000cc through to all sorts of European beauties with tons and tons of horse power.
This old guy on this bike (age about 65), with drum brakes not only was keeping up with us but was passing, and scrapping this heads on the road all on knife edge tyres.
The road was very twisty, up and down dale where the power delivery from this old bike still shone. Also he kept a whopping pace once the road straightened up.
It’s the person ridding the bike that makes the bike.
There is no dought that German engineering is very good but back then it came at a price. I have an older brother of 12 years and he goes back to the early sixties ridding bikes. His first bike was a Honda dream, followed by a Triumph tiger 650 which he constantly tried to stop the motor from leaking oil. Peace of piss today with the silicon sealants’ on the market today but back then there wasn’t any. That along with the early Japanese stuff made way for the BMW with its reliability superior over the then field of motor bikes on offer.
Ordinery people could not afford such a bike back then they wore simply to expensive and money was not on loan like it is today, so people went for the cheaper bikes on offer. I can always hear my Brother saying that one day he would own a BMW.
We both ended up living together in 1988 and we both went out and purchased together a couple of K100RS each. My brother kept his for 10 years only to loose it in a garage fire 8 years back, if not for that I had no dought he would still have it today. I kept mine for 20 years and unloaded it 2 years ago. I put 160,000km on it and in all that time the only thing that went wrong was that I broke a clutch cable.
I currently have a R1200R and can honestly say that it is the best handling all round bike I have had. I have had 15 motorcycles up to date and would not rule out owning a water cooled boxer if and when one came out.
I feel it has to go that way for BMW to keep in Vogue with other manufacturers’.
I like many will wait in anticipation.

Cheers Kieran
