99 R 1100 S belly pan

[kooze1948]

Hi all,
Sorry if this subject is covered in another thread, I could not find anything related to it. I bought an aftermarket belly pan for my 99 R1100S from Gimbel Motorradtechnik in Germany. Pan arrived with installation kit but no instructions. I was hoping that installation would be similar to a BCR bike but none of my manuals cover them. I've yet to get a response from Gimbel, in the meantime does anyone have any suggestions as far as where I might get instructions? On another note, thanks to all the info and encouragement that I found on the Forum I installed a 5 1/2 " wide rear wheel and tire, looks great, see attached.
Thanks in advance,
Kooze 1948

You will need to remove the center stand. Remove the Kickstand stop. The rear holes line up with nuts already in the frame. The front bracket mounts to the bottom of the engine, if you line up the rear bolts to the rear frame holes/nuts you should be able to see where to line up the front bracket on the engine.

Probably want to make sure your bike is right side up during installation, too.

Happy to help.

Seriously, though, beautiful bike. I had a mandarin orange 99 S and still miss it.

I would have thought Kooze had the bike setup in the best position that would give him the easiest access for installation of the belly pan. Of course I am certainly no mechanic so I could be wrong..

Sorry about the picture, I guess I need to really keep the rubber side down. Thanks for the advice. I also have the Mandarin Fuel tank and Headlight surrounds.

Did the belly pan come with the front mounting bracket that affixes to the frame. I take mine off quite regularly. But it came with it. I do recall the first time I removed. I was a little nervous due to the replacement cost.

Did you get the BP install sorted out?

I made a front bracket for the stock, carbon fiber belly pan years ago. Found very clear hand-drawn layout illustration on line. Very easy to make: two metal straps bent, drilled and bolted together. Mounts on the forward horizontal through hole on the bottom of the engine case. Two BMW nut plates attach the bracket to the pan’s forward holes. OEM, locking, BMW TORX-head machine screws are recommended. They aren’t cheap but neither is the belly pan dragging on the ground. The screws have a longitudinal nylon insert. Thread lock might work using conventional machine screws but blue only; no red as heating the screw would most likely damage the paint and or the pan itself.

I have seen aftermarket fiberglass copies of the CF-pan. If this is what you have, you’ll need stand-off spools for the rear mount. They fit in the frame holes where the center stand would be on a non-belly panned S. I drew these to scale with dimensions. I didn’t have to make them as they were included with the BCR. They should be fairly easy to make out of aluminum or Delrin on a hobby lathe or to 3D print. A broom handle down would probably work, especially if the pan is made from CF. The stock pan weighs 1.25 LBS. Don’t know how the front mount got lost.

I believe I still have the drawings. Let me know if you want a copy.
