When I did them on my old K1200 I had problems with the dust seals.

The first set just wouldn't push in and I ended up damaging them, the next pair I had to Dremel some material from the OD to get them in the top of the forks.

The oil seals were easy.

Doing the fork seals is a piece of piss, don't even have to take the wheel off. :D
I did have a look and would do it myself however my bike doesn't have a centre stand and I need that Abba stand!
Come and get it! :D

(where are you again?? May be able to meet half-way?)

I don't remember ever having issues with the dust seals... maybe a bad set? (maybe corrosion at the top of the leg had made the aperture a tad smaller?)

I think they were just poor 3rd party copies of the OEM BMW part.

I know it sounds a bit poncy, but I always prefer to get genuine OE over aftermarket stuff, unless the after-market is demonstrably "better" than OE, irregardless of price. For that very reason.

Yup, if I had to do them again I'd buy BMW OEM.

Noticed last week a slight weep on the fork seals - seals serve little purpose on these other than to keep the lube within the tubes but need sorting nonetheless. Contacted the selling dealer and they have authorised a local indy to do them for me FOC, pretty fair I think as fork seals are generally fair wear and tear.
They all do that, sir!
As has been pointed out, it's a 1/2 hr repair.
The forks dont actually 'do' anything apart from attach wheel to bike, the oil is just for a bit of lubrication. Just make sure it doesnt drip onto the pads and you're golden!

To be fair if it hadn't came from a dealer I would have just ran a cleaner down the leg - probably just a bit of crap in seal. They offered, so I accepted.....

Seals replaced today.

Not sure local indy is too familiar with telelever as wanted to totally drop out the forks and replace oils too, not sure he believed me when I told him it's only for lube purposes and not damping!

Going forward will likely do all maintenance myself, especially if @Rockburner didn't have the Abba stand pinched in his recent theft......

Ouch - yeah - sounds like he wasn't a BMW knowledgable, hope you were able to educate him!

Yes - as far as I can see, the ABBA is still there all complete so whenever you're down this way. :)

Few times I've rode the bike I felt that the front brakes were lacking a little (lot!).

Decided today to pull out the pads and take a look - Goldfren FFS! Straight to the bin and ordered a set of EBC HH, which I tend to gravitate to for road use pads.

If the calipers are Tokicos I highly recommend swapping for Brembo (are they EVO* or not on the R1100S?) Talk to Motorworks*, but, from memory, the calipers and discs from the R1150GSAdventure are Brembo and fit the Rockster (which means they should fit the R1100S as the two models share the front end).



* I'd be completely lost with them.

They say BMW on them, believe that they are Brembo Evo?

I've always found organic/oem compound best for road use. HH need heat into them to work best and often in normal riding the just dont get enough imo.

I never knowingly tried organic pads. The last few road only bikes I've had have always been fitted with EBC HH and I've found that once bedded in they work nicely, perhaps because they've all been heavy'ish bikes?

Brembo come well recommend for this bike but at double the price of EBC.....

Yes - I didn't look closely at the pics. Those are Brembo alright.

Might be worth a strip and new fluid. The hoses are already braided and it's nonABS.

Calipers seems really clean but I'm tempted for a fluid flush. Yep, braided hoses and non-ABS...

Other nag is the clutch slave - may just drop a new one in to be sure.

Clutch slave is easy enough (although on the S might be a bit harder because of that sub-frame), but they're not pricey.

Less than £100 for a Magura one - better than a new clutch I guess!!!
