BMW R1200RT/R1250RT Forum

At this stage there are very few videos about ABS on YouTube that I haven't watched. This is by far the most informative I've watched so far: https://youtu.be/Y3_ysMMzCAU Yes, there seems to be very little about camheads. Same ABS as far as I have seen in videos but likely the ABS will be harder to ...

Has there been a formal centralised collection of information on parts for the R1200RT made on this forum yet? I would like to collate the aggregate knowledge of members to produce a helpful repository of information not available in the Haynes manual. If anyone has make and model information (and b...

After looking through the previous three owners paperwork I can see the second and third owners pretty much left the bike sitting in a garage. It has spent very little time in the sun by the look of the paint, although the yellow window on the tank bag would disagree. I have come to accept that I wi...

The service history is a moot point.... what BMW is charging for ABS units is highway robbery. The fact that so many people think that dealer servicing / extended warranties are the answer shows there is little understanding of the incompetence of Australian dealer workshops and even less interest i...

I haven't been seeing any undervoltage errors in the last two months and the bike is cranking over normally and has no other errors, just the pressure sensor. I see I have five possible courses of action... 1. Replace the ABS unit at AU$4000+ if I can find a BMW service tech I would trust to install...

Oh dear... I have been getting undervoltage and wheel sensor errors and somehow I've not read and realised the error had changed to pressure sensor. I have a wheel sensor on order that likely won't fix the problem. To compound this, I have a local BMW dealer who, given the accounts of their service ...

The error clearly indicates the rear sensor is at fault. I don't know how pressure comes into the equation? It will either be an intermittently faulty transducer or a cable/connector issue relating to the rear sensor circuit?

The rear ABS wheel sensor is faulty according to motoscan. These sensors aren't replaceable? I have seen people replacing them in YouTube videos. Looking at the circuit diagram, pin 50 of the ZFE unit handles the brake light switching based on info it gets from the ABS Control unit??? There doesn't ...

Well it has started throwing up the error when I first start off. Interesting to note that when the ABS fault occurs, the brake light stays lit until the bike ignition is turned off. If you see this error on your dash please make sure you don't have any vehicle behind you as you slow down to pull of...

Well if gel as good as it gets and since I am still getting undervoltage errors for my ABS then the only option left is that the ABS system is crap... which couldn't possibly be true because BMW wouldn't possibly allow as poor an ABS system as they used in the 1150 model... Ohhhhh wait... how long w...

Gel @ £67 for 3 to possible max 7 years service Equates to £22.00 to £16.40 per year Versus Lithium @ £114 for 10 to possible max 15 years service Equates to £11.40 to £7.60 per year Therefore gel isn't just more weight on the bike, it's significantly more hefty on the back pocket over the life of t...

Seeing that most people are getting pretty short life from their gel batteries the AU$160-240 for a decent lithium battery sounds like a good deal. I have lithium AA batteries I purchased in 2010 that are still going strong.

Well if it's that easy why would anyone bother with gel or lead/acid?

Why does the alternator need to be changed? Ideally a lithium compatible reg should be used to charge a lithium battery. When the alternator has an integrated reg and that alternator has no upgrade path to lithium reg available the option is to replace the alternator with an alternator that has the ...

I believe some better lithium batteries have a good quality bms built into the battery. Apparently the cheaper ones don't. I was wanting to change to lithium because they last 10 to 15 years. Much more than the gel battery @ 7 years and the lead acid at 5 years (good quality versions of each). Lithi...
