Nice. . except (1) it's ugly (2) the torque curve looks like the Great America roller coaster ride (3) it rides 1/2 inch higher than the R12r using the Low Seat (4) it's heavier. Other than that. .

 

[drDave]

That's the GS with the Low seat riding half-inch higher than the R12's regular seat. Too tall for me, even if it was all tickety-boo

 

[drDave]

Will try to upload the torque curve here.

 

[Clem]

Not ugly. Butt ugly. Fugly.
The front fender looks like you have already rear-ended someone.

 

[Clem]

That is NOT a torque curve.That's a graph of my wife choosing a pair of new shoes.

THIS is a torque curve!!!
The 1996 R1100R pulled like a Clydesdale.
Not spectacular HP by today's standards, but shift lever was optional.

 

[drDave]

Really. . .between the can opener front fender and the "you must be this tall to ride this ride" torque curve. . .wow. Maybe BMW will just put some icing on the cake by painting the bikes InvisaBlue and Desk Accessory Tan.

This is a bike needing a few years of engine development, I think. . .along with wholesale mass firing and public media ridicule of the aesthetic/design team.

:idisagree:I get what they are doing with the fender, they want to incorporate some edgy styling of the s1k. Take some werewolf teeth and make people look twice. :001_9898:I'm going to wait until they get the motor really humming to about 150hp then I'll be impressed.

It's interesting they changed the side of the rear swingarm. I guess the new tranny but why change the look. Assuming they are the same config. of our r12r

I really do dig the look of the bike though. The tail looks tidier, not such a huge license plate holder. The rear fender and the modern look of the timing cover. Tank looks big and purposeful. They will slowly keep adding more and more timing and compression and they will have a screamer.

There were two specifications on my list that I failed to get when buying the R1200R, a wet clutch and liquid cooling.

I was willing to forego them for other considerations.

I wonder, though, just how much of the BMW "legendary" reliability is due to the fact that most owners can afford to schlep it to the dealership on regular intervals for replacements of clutch, final drive, electronics, etc., but who consider it "reliable" because the engine didn't blow up? I concede that the engine is tried, true, tested and reliable. I'm going to wager that all the rest is going to prove more problematic than the 'ol Honda... :2guns:

 

[drDave]

All other things being equal...I've still never seen a torque curve like that; now it pulls, now it doesn't ...oh..wait it's pulling again....

2011 R12R Torque curve - also a bumpy one

I got curious and looked up torque curves for the 2011+ R12R. The curve that I am linking to here (Webbikeworld.com) matches with other dyno test curves I found online as well.

http://www.webbikeworld.com/BMW-motorcycles/2011-bmw-r-1200-r/bmw-r-1200-r-torque-curve.jpg

Considering that I have no complaints about torque through the RPMs, I don't think it'll be an issue on the '13 GS either.

That torque isn't as lumpy as it seems. It is plotted with the lowest value at 80 Nm, not zero, like most curves you see. In other words, it is zoomed in in such a way as to exaggerate the vertical height of the lumps. The existing R1200 motor has its share of lumps, and I would bet that when you plot them both on a common scale this one won't look any worse.

 

[avocet]

It seems that BMW is claiming that the new engine still relies, at least partially, on air cooling, and that only portions of the engine that are particularly stressed by heat are being cooled by the water/Glycol (antifreeze) mix. This, they claim, keeps the radiators smaller than on bikes that rely more completely on air cooling.

This is an interesting idea, and makes me feel better about the direction BMW has taken with this engine. I was expecting the engine to be totally reliant on water cooling, like other water cooled engines, but that would really have destroyed the whole reason to use the Boxer configuration in the first place. The big advantage of the boxer on a motorcycle is that both cylinders hang out in the air where they can be efficiently cooled (compare this to air-cooled V-twins where the rear cylinder runs hotter than the front because of lack of air-flow). If the engine is water cooled, there are probably better configurations to use.

In this new engine, it seems that BMW has used two small radiators to replace the oil cooler that has been used on the air/oil cooled boxers, and the new radiators cool a coolent mixture that is more efficient at removing heat than oil is. The size of the cooling system is kept almost as small and light as the oil cooler it replaces, and while this must require the addition of a water pump, the old boxer had two oil pumps, one to force oil through the engine, and one to pump oil through the cooler, so one of those can probably be eliminated. An interesting engineering solution that retains the justification for using the boxer configuration, while also improving cooling capability.

 

[drDave]

so why is it 20-30 frickin pounds heavier than the 2012?
