BMW R1200RT/R1250RT Forum

[size=15px]Hi greetings from Ireland, I have 2005 R1200RT with 38k miles, the ABS servo is working but planning on bypassing it very soon, and upgrade the fuel pump controller, the ESA is working perfectly and what advice would you recommend to maintain and keep it working order, what setting to leave it in and take stress off the motors? Thanks folks [/size]

On my 2012 Camhead, the ESA is set to COMF: Comfortable damping and One-up: Load. AFAIK, the motors are only active (moving) when changing the settings.

It might not do any harm to occasionally change the settings to check the operation of the damping and load settings.

Why bypass? As long as they are working, they are wonderful, and you'll lose the ABS. Loved them on my GS. Not that I didn't fear the day something went wrong with them,. In theory, Module Masters rebuilds them now.

Thanks guys, anyone else, can comment on the ABS, it’s working perfectly, but heard horror stories about the servo failing and ending up with no braking at all,

Should I leave it or bypass it?

You still have brakes, but effort will be very high. When you have space, turn off the key and see how hard stopping is, low speed and plenty of space to recover! And you'll probably get a warning light before it dies completely, I hope. Do flush regularly, look up the procedure, easier with a GS911, but can be done without.

I would assume it would be harder because the ABS pump/servo is still connected, I would  assume the brakes would be ok direct,I drove bikes for years without ABS, and without rider aids,

If it works leave it alone

I covered 60,000 miles on a 2006 RT over 8 years, never had an issue with the servo brakes. Brake fluid changed regularly probably helped. They don't all fail, and it's only the failures you hear about.


FWIW

The wizzy brakes are unusual, you have 4 fluid reservoirs, not two, there is a connection, but effort is much higher when they are off, if you're used to ready two finger panic stops, you could have a problem. But, they generally don't die without warning, and are wonderful.
