Default Advice needed: BMW K1200rs ABS removal

Hey lads,

Looking for a bit of advice from someone who may have done this before. The ABS unit on the bike died so I decided to get rid of it (the unit not the bike). After a bit of a google search it seemed fairly straight forward. Replaced all the lines while I was at it with braided ones.

All went well apart from the electrical side .... The ABS unit itself controls the speedo and the brake lights, so I removed the electrical part and kept that plugged in (As per Chris Harris' vid on youtube).

All seems grand apart from the brake lights being on all the time.

So my question is does anyone know how to get them to work? (I know its something to do with providing a live to the 2 brake light switch wires in the top of the ABS unit but I havent got a clue which ones)

Any Ideas?

Cheers

On my 1150GS, I removed the electrical component from the ABS unit/reservoir, and plugged the wiring connector back into it - I think this is mentioned in Chris Harris' vids for the 1150GS - may be the same for the 1200 but maybe not.
I had to drill out a few security bolt heads, then was able to seperate the reservoir/pump motor part from the circuit board section.
It's either that, or reusing relays from the pump as ones for the running/brake light that sorts it out

Yeah I separated the circuit board section and plugged that back in. I thought everything should work after that but for some reason the brake lights are on constantly.
Think I need a wiring diagram

There's a possibility I left something unplugged that might be causing the issue... will check this tonight.

Here's a post that mentions reusing the ABS relay for the brake lights - I knew I'd seen it somewhere! This worked for me on the 1150 - it may do the job for you on the 1200 with any luck!

Great information in that link ..... Thanks for the input man much appreciated

All sorted now, turned out it was a broken front master cylinder wire up near the headstock.

Are there implications for ins in the event of an accident if you have your abs removed?

I get what you mean dude, but a bike with no or very little brakes/dodgy abs is far more dangerous imho. I'll take my chances with the insurance ... hopefully I wont need it seems as I can stop real good now.

As for the modifications .... wonder where they draw the line? Is an aftermarket exhaust ok seems as its not a safety device? or what about aftermarket brake levers...would you tell your insurance company if you changed them? (just wondering, not havin a go at ya)

I know what you're saying but if you have an accident the ins cnuts will look at your bike and say
"You removed a vital safety feature" and drop you like a stone.Then you'll be on the hook for any and all costs even if the accident wasn't your fault.

To which you say "no I didn't, it must have been the previous owner" - they can't prove who removed the system

as mentioned above, if insurance was optional, I'd say the number of people that would actually pay for it would be very low

There'd be a lot less accidents if that happened.
