ABS Pressure Modulator failed (again) - 2005 R1200GS

My first bike was servoectomised

Never had a problem, as i never got into a situation where i needed abs, i locked the back end once, noted it didnt need shit loads of pressure, and adapted accordingly.

When it went for an mot, it passed, nothing was noted about no abs, and they dont test for it
Thanks - I have relied on the linked brakes + ABS (rarely activated) up to now, so I'll need to relearn 'proper' braking!
 
I discovered a company based in Spain that advertises repair of BMW bike ABS modules, although more expensive than the bypass option it would retain full functionality - https://www.nitomotor.com/en/reparar-modulo-abs-bmw/ - has anyone used them?

Not sure if there is an equivalent in the UK, but so far I've had no success in finding one

Ask yourself this question

How many times in my years of ownership did you get into a position that your ABS kicked in ?

How many bikes prior to your GS

A) Had Servo ABS
B) Had the ABS operate

if the answer is zero, then do we need to say more

The early GS didnt have servo brakes - ever thought you may have had one of those ;)

I totally get your point:
- none of my previous bikes had Servo ABS - but then again I came off a few times due to heavy handed braking (totally my fault!)
- how many times has the ABS activated? To be honest I'm not sure, but I do like it being available just in case something unexpected happens.

The truth is that I have extended warranty on this bike (and I know that may sound silly to some) so I would prefer that BMW Motorrad Warranty pay to get the bike back to its original configuration if feasible. If that proves impossible I will go down the 'servoectomy' route - I have no problem with that assuming that my insurer doesn't have an issue with the modification - and if they do I will just have to get a quote from a different insurer.
 
is this fixing ABS2 or the earlier one no one can repair ?

you only need ABS to help fully once for it to be worthwhile

in a BIG moment if you had time to notice if ABS was or wasn't cutting in it was never a moment - its a bit like beeping your horn if you have time to do it - it wasn't even close to ever being an issue worth noticing
 
I have a 2004 1200 that has had the servosectomy and the brakes are amazing and I've never had any worries after making the decision.
I never have to worry about the triangle either, great bikes the early ones .
 
I believe the unit in my 2005 bike is the 2nd generation version (2000 - 2006).
Yours will be the Servo ABS in a 2005, the better non-servo ABS system came later.

FWIW I hated my Servo ABS brakes, they were like an on/off switch with little braking feel and could hammer on quite severely at times. When they failed and left me with only pathetic residual braking it was a genuinely terrifying moment.

My later 2008 bike with the non-servo ABS was in a different league.
 
I'm slightly dreading when/if the servo brakes go on my 04 model. They're some of the best brakes I've ever experienced. 1 finger braking and the force is unbelievable. I've had much more modern bikes with brakes that aren't even close to them. I keep hearing so many horror stories though!
 
So, I first had a problem with the ABS pressure modulator on my 2005 R1200GS in 2008 when it was replaced free as a goodwill gesture. It failed again in 2016 when the bike was 11 years old - this time it was replaced under extended warranty (which made the warranty seem well worth it!!!).

And this last weekend during an afternoon ride to bed in my new Conti-Trail Attack 3 tyres I once again got a solid red triangle + rapidly flashing brake failure lights come on. The front brake servo was activating but pressing on the rear brake pedal = nothing (or residual braking only).

Took it into the dealership yesterday for analysis, and was told the modulator had failed again. Only now apparently BMW don't have this part (# 34 51 7729061) available anymore - it is officially obsolete!

I love the bike (which I've had from new), so I really don't want to give it up. My dealership said that it is possible to get a part from Motorworks which would bypass the pressure modulator which would give me braking but with servo assist or ABS - I'm wondering if this is the right path to take assuming that BMW UK can't find a new part anywhere else... has anyone else used this method or done something else I should be considering? TIA
Check with another dealer, I have had it with obsolete , no longer available BMW motorrad parts that there are still some in the system and they can be ordered BUT they are on a non returnable basis , ie the dealer cannot return them to stock.

I bought a r1150gs ignition switch a few months ago that is listed obsolete, nla by BMW but was available from a motorrad dealer

I'm interesting in how you found the motorrad dealer with the 'obsolete' part - lots of phone calls?

Indeed, you are scavenging parts bins for whats called New old stock

It's luck that you got the part, they are obsolete, and once they leave the central WH thats it

Dealer I use checked and system which stated nla and obsolete but the parts manager said that it does not mean parts are not there , he re -inputted the part number into the system and lo and behold there were a dozen or so in the UK.
It is how Motorworks has so many nla parts

So you think the mothership should keep a production line available, just for you so you have a spares supply when even anything on your 26 year old model that ceased production 20 odd years ago breaks down :blast

no....

two iterations of the ever die fiasco - then late 2006 they got the modern style - the naming conventions used by BM are all muddled

ABS2 is the third iteration and like most cars 2006 to 2012

I've never said that if you read my post.
BUT I can go to any Suzuki dealership and over 90% of parts for my 1981 ( a 40 odd year old plus bike) Suzuki GSX1100 SZ Katana are still available and Suzuki regularly make up production batches of parts that are requested .
For an ignition switch (electrical part) and a known failure part for an R1150GS to be listed as being obsolete and No Longer Available is a bit ridiculous as the part was used on all of the R850 , r1100 , r1150 ranges plus numerous K series bikes .

He hasn’t said that…. Oops, just seen Neil W has replied, in big letters to help you understand :D
 
I’ve had a few insurance repairs involved in accidents that have had the servo/abs removed and insurance haven’t queried the removal.

I've just checked with my insurer (Bikesure) about by-passing / removing the ABS and they say they have no problems with doing this, provided the bike is "safe to ride".
 
As legality and insurance issues often come up when discussing the elimination of the ABS system, I have a question. I live in the northern part of Sweden and have been riding motorcycles for almost exactly 40 years (I'm 56). We have an inspection every other year, similar to the MOT test, where the vehicle's roadworthiness is checked. They don't test ABS, which on slightly older motorcycles is extra equipment. Eliminating the ABS system is therefore not a problem where I live. It seems that in other countries it could be a problem, or? On my 2010 R1200GSA I have a button that allows me to turn off my ABS which is necessary when riding in terrain/off road (otherwise no rear brake). Is it legal to use that button in countries where you are not allowed to dismantle the ABS system? What is the difference between switching off via a button or completely removing the system?

do you turn it all off or just the back wheel's ABS ?
if you brake hard the back wheel comes off the ground anyway
