BMW R1200R R1150R/T F800 K1200R R1100R/T R1250R RnineT Message Board

Hi everybody,

please have a look at my R1100R. After all the modifications it is the best oilhead I have ever had ... 101 horses and 112 NM and she runs smooth as silk ... Hope you like it.

Kind regards
Oliver

very very very nice.

Where did ya get the fairing?

And the wheels? Details man, details.

The fairing is from Wuedo (http://www.wuedo.de/indexeng.htm) - product name = CR11 fairing. I bought it "nude" and got it painted in the color of my oilhead (pacific blue).

The front wheel (originally from a R1150R) was bought "used" from a german company like beemerboneyard.com and the rear wheel 5.00 x 17 type MTH2 (off aan earlier K1200RS - aka the "flying brick") was bought used via ebay. Be careful, later models of the K1200RS hava a larger wheel (5.50 x 17) suitable for a 180 tyre, that one will cause problems as only about 1 mm is left between the tyre and the drivetrain. Better to use the 5.00 x 17 wheel suitable for a 170 tyre. But both of these wheels can often be found at beemerboneyard.com I got both wheels chemically delacquered and powder coated (RAL5026) and then new bearings installed in the front wheel.

And before I forget, the front wheel requires a modification: on the left brake rotor mounting points 3,9 mm need to be milled off. The reason is that the ABS ring of the R1100R (cast metal) is different from the ABS ring of the R1150R (made of metal sheet). The only suitable replacement is the ABS ring of the R1100S (same as the one of the K1200RS). However this ABS ring is 3.9 mm thicker than the ABS ring of the R1150R hence 3.9 mm need to be milled off.

Then off course new brake rotors are required because the R1100R (305 mm dia) has floating rotors whereas the R1150R (320 mm dia) has fixed rotors with 5 mounting points. Suitable discs would be those of the older R1100S (upto 11/00) with 305 mm dia. However as real BMW stuff is horribly expensive I have taken OEM rotors (MST239) and pads from a company called Lucas (cost is about half of the real BMW stuff and the quality is the same). You would also need the disc rotor fasteners and washers for the R1100S.

Last but not least the speedo drive of the R1150R is also required which is thicker than the speedo drive of the R1100R (as the hub of the R1150R wheel is slimmer than the one of the R1100R wheel).

The rear wheel does not require any modifications and all screws (as well as the axle of the front wheel) can be re-used.

The whole wheel excercise (including the 2nd hand wheels, powdercoating, brake rotors, fasteners, brakepads, and new tyres) did cost me around 1200 Euros.

That's all I can tell you. Hope all this helps ...

Best regards from Germany

One hundred and one horsepower?
Boxer 1100's are 80 horsepower where did you find the other twenty?

cheers arbee

Yep, 101 HP and 110 NM torque ... as per dyno. The dyno report shows the HP/torque without the Bodis exhaust (red diagram) and with the Bodis exhaust system (blue diagram). The blue diagram shows 101.0 HP and max torque 110 NM.

As I said, Woesner pistons, Schaeffer camshafts, tuning chip, K&N airfilter and the Bodis exhaust system. That is all which was done.

Absolutely one of the best Roadster projects yet documented. Ausgezeichnet! Congratulations on excellent selection of components and restrained customization.

The closest thing I can recall would be one of the following:





But the R1100R has a certain elegance that is superior... and now you have created a bike with the guts to match.

Hi sweetmark,

thanks for the flowers. However I prefer mine over the ones on the pics posted by you. Ever since I owned a R90S I am a fan of the round shapes and forms which the R1100R perfectly resembles. The ones you have posted are more of an "edgy design". But that is just my personal taste ...

@arbee
I believe you are based in Australia? The parts I have listed are probably not available down-under. We have the advantage of having a fairly large community of oilhead fans and hence there are quite a few manufacturers of (tuning- and OEM) parts for the oilheads. Woessner is a manufacturer of forged pistons and (Dirk) Schaeffer is a man who has designed supreme camshafts for the oilheads. These camshafts and pistons are used by almost every tuner in Germany who puts his hands on the oilheads. With regards to the tuning chip (located in the motronic under the tank) we have 3 or 4 producers of these.

The Bodis exhaust system is one of the best available exhaust systems without creating inferior noise and without sacrificing on the catalytic converter. It is made of stainless steel. But is is rather expensive (cost here is about 1000 Euros).

With the above measurements the R1100S is upgraded to 115-120 HP and the R1200S to 128 HP. With some further modifications on the heads and the airflow I believe the R1100R can be easily brought to 105-110 HP. But that is another story. I am happy with the way she runs right now and apparently this does not sacrifice on the durability as I have some fellow riders who run their oilhead with the same configuration for over 70 000 kms without any problems.

Kind regards
Oliver

Really impressive! Not to take away from the effort but, it's amazing what a few parts will do. You really chose well. The telelever, oil cooler, center stand delete, and exhaust really trim the bikes lines. The bike is transformed. I like the wheels too. Thanks for the inspiration!

Well by golly! That looks like the same Wunderlich service stand I use for my R1200CLC. But that bike doesn't come with a center stand.

Wow, nice looking machine! I especially like the elimination of the stock oil coolers which always detracted from the overall look of the bike IMO.

The bike looks so much cleaner, sleeker and lighter while still being *very* classic (maybe it's just the missing oil coolers). Very easy on the eyes! Any idea what the weight difference is?

Sorry, I don't know what the weight difference is.

And with regards to the service stand this is from a small German company (Becker Technik) who made this for the R1100S ... Cost is a mere EUR 72 (but I found it on ebay for EUR 52).

Changing the oilcooler is not a big deal. I used the cooler of the R1150GS which is a slightly larger one of the oilhead coolers (I believe the largest available are those of the R1150GS and RT). Plus the connections of the GS-cooler stick out to the right and left of the cooler which is ideal for my purposes. Cost of the cooler (used) should be below US$ 150. Next I cut off the oilcooler lines and got flexible (steel braided) oil hose attached to the remainders of the original lines which is then attached to the cooler with clamps. Cost was a mere US$ 50 at our local hydraulic service. Last but not least for the holders I got myself some stainless steel from the local toolshop (2 mm thick, 1.5 cm x 50 cm) which cost some pennies ... some bending, sawing and drilling and that's it ... So the whole excecise did not cost a fortune. However since the oilcooler is not ideally located in the airflow I believe it should be used in moderate climate conditions only and it will not be feasible in the Death Valley area ...

If you want more detailed photos just let me know.

Kind regards
Oliver

Thanks Oliver

Realistically 1000 euros for 20 horsepower extra is money well spent, i reckon
my next question is why cant BMW do the same things?? as they seem to want to compete at track level
now and mix it with the japanese sportbikes, so they have obviously looked around for more horses.

cheers arbee

Hello arbee,

I paid 1000 Euros only for the exhaust system. For the engine modification I paid over 1000 Euros which included the pistons, camshafts, tuning chip as well as mounting the parts and a consecutive sync.

However the engine modfications alone resulted in 97 HP. The exhaust did bring "only" about 4 HP but a much better torque ...

Kind regards
Oliver

Thanks for the inspiration.

Hi there, Oliver~

Thanks alot for posting pictures of your R1100R. It has given me a wealth of ideas for my own. The only possible improvement that could be made to yours is the addition of a Hannigan fairing.

Hello Mr Thiu,

I would say that is a question of personal taste. I have had a look at the Hannigan website and I personally think their fairings look rather bulky. In my young days I had a R90S and I always liked that neat little round dingle fairing and that is why I bought that one and no other.

Kind regards and happy new year!
Oliver

Hi there, Oliver~

I apologize! I guess my sense of humor came off a little bit dry (maybe I should have added a little smiley face)! I just thought the irony would be humorous, adding a huge Winnebago fairing to a performance motorcycle. Your bike is amazing, those Hannigan fairings look horrible and would completely ruin it's great neo-R90S look. Anyway, cheers and Happy New Year to you!

OK now I got it. Sorry for my slow brains ... Same to you and safe ridin'.

Kind regards
Oliver

Oliver, one thing I wanted to ask about your choice of wheels. I, too, am considering a change from the stock three-spoke rims to either the five-spoke rims or traditional laced-spoke rims. I'm guessing you considered laced-spoke wheels as well, and what made you decide against them?

Thanks~Matt
