But it could be that the original bolts will be just fine, because this is depending
on the disks you are using and if you are using any spacers between the
disks ond the hub.

I am using K75 disks and with the 48mm Brembo calipers I had to use one
spacer (the 0,8mm spacer from BMW) on each side in order to have the
calipers centered.
With the 4-pot Brembos I had to remove the spacers again and now I could
propably reuse the old bolts again.

I think I forgot to mention that the left caliper is connected to the right one
with the brake tube from the R100R. So you don't need to buy an extra brake line.

This is great info. I have an extra caliper and two rotors from the K75. Since my bike has the HPN fork with mounts on both legs, I'll only need to add a bracket, the crossover tube and perhaps some spacers. Thanks for posting!

Well, I think i found the brake upgrade I'm looking for.

I'll just have to start shopping for parts and save up.

Thanks much for the good information.

Hi Bob,

you can try BMW used parts dealers. At least here in Germany they know
this modification and some offer used fork legs which are already changed.

(e.g. Boxer Shop Krefeld but I don't know if they speak english)

But I would recommend just to buy the parts and have them modified by someone local.
It is really no rocket science and the left fork slider can be used as a template.

Regards

Bernd

Question R100GS Stainless Replacement Rotor

I read somewhere about a replacement stainless rotor and I can't seem to find it. I need a new rotor for the front of my 95 R100GS but don't have the money for a M.A.P. upgrade.

I did the old-to-new Brembo swap. It's the same caliper as on my R1100S (left side), but I got mine from a K-bike.

See some info here: shave a caliper

By the way, if you call cyclebrakes.com
and mention ADVRider they'll give you a discount. I got an EBC rotor and pads a while back. Very nice hardware...


I'd get the steel brake line while your spendin'' yer hard-earned cash...all available from them.

Not mine, from www.ibmwr.org

GSPD rear shock and floater rotor
From a '93 GSPD I have a rear shock. Lower bore was cracked and weld repair carried out which has held up well for a further 20k kms until I replaced it with an Ohlins. Shock has a total of about 40k kms. See pics at my smugmug link. Also a floating front rotor from the same bike minus the carrier. This rotor is straight and measures 5mm thickness. See pic at link. Price is $40 for each plus shipping.
Price: $40 each
Location: Calgary, Alberta

They use the leftside pot of a r100r, which is the same as most brembo 4 pots, eighter 2V-R, K of 4V-R.
Take a look at ther picture #2 showing how the disk will not be aligned with the pot, some machining has to be done... A good solution for this is upgrading the disk to a HE one, http:/http://www.he-motorradtechnik.de/
(Look under BREMSE, scroll a bit to the first one you see, it's on a GS) they are 320mm and add a lot of stopping power to the standard pot as well. These disks come with a large spacer to fit between the wheel and the disk itself, if you take of 4.5 - 5 mm from this spacer it'll will fit without having to destroy eighter your fork-leg or the pot itself.
I use this combination and am very happy about it There is no need to change the master cylinder as far as I'm concerned.

Is a new master cylinder needed? No one seems to mention one. Not necessary?
