ABS Controller / Pressure Modulator Service 2006 R12RT 45,000 Miles

Thank you BMWMOA for assistance with supplying the 17 page direct to the point fluid change for the Anti-lock brakes. The fluid looked really good so I might prolong the service interval by several intervals. The system is so over-built that the recommended modulator service interval is perhaps merely a recommendation and applicable to two-up riding, loaded down and living off the bike for weeks on end. The fluid looked that good. I did over tighten the ventilation valves breaking the top off of the rear power assist unit. So to the SF BMW to pick up a new one. Only $102.00. While at the shop substantial hubbub ensued as an unwelcome customer attempted to test ride a customers GS. Man what an episode the parts and service staff didn't need. I didn't find it amusing either. Imaging trying to run a business in a retail environment thus.
The biggest issue of tank removal is the requirement for space and emptying adequate quantities making the gas tank removal possible. I can now remove the fairing panels and tank in under an hour. I bought a siphon bulb on Amazon and used a good thick suction side uptake line that permits access to crevices. Total job my 2nd time performing, under 4 hours. Total fluid extracted was 250-300ml. I used Prestone. There's a reason it's number one. The RC car fueling Nalgene squeeze bottle dramatically cleans up the process enabling accurate dispensing of fluid during the feed and bleed process.

The fairing comes off pretty regularly now at every oil change. The tank only for the occasional brake modulator service. It's only 4 screws and including siphoning only takes at most 40mins to properly remove. I am becoming so adept at service. I might never get rid of this bike for sake of familiarity with mandatory maintenance. To me all is mandatory. This bike was expensive and I knew from past experience what happens to many of these super machines. They become neglected and fall apart. This bike has been absolutely 100% reliable, I could ride across the USA tomorrow on it. It's that good.

Just a heads-up.... How it looks is only one factor in the decision to flush the brakes.
Brake fluid gradually absorbs water from the local air (is SF BMW San Francisco?), which reduces its boiling point and thereby its effectiveness.
The standard interval is two years regardless of mileage traveled, and one year is "recommended" if you have ABS and live or travel in high-humidity areas.
 
SF or San Francisco Motorad. Great speedy service. Pricing is consistent with online retail but the service was great and it was nice to look at the R13RT and sit in it. Wow, I don't know if I'm ready for all the automation and dual mode setup but reports are glowing. Making novice riders hammer down safely. Think of it, the time you've spent learning to modulate and look as deep into a corner is now done by radar assist. Alas some features make sense, sure. Things like lane minder are appreciated but 400w surround stereo? Excess complexity for the sake of adding weight negating largely the increase in performance. Extracted BF was moisture compromised. Evidence the streaky and hydro-suspended water nodes. Braking before was solid, now it chirps the front tire! Much more progressive and almost knowing in advance your level of lever force pull commensurate with a panic stop or a normal traffic stop.
