1150GS Servo or is it?
- Thread starter mad-dawg
- Start date
If it hasn't got ABS it won't have the servo.
If the rocker covers are like the 1100GS's, it won't have the servos, as it'll be a pre 2003 model ie like: http://www.google.co.uk/imgres?imgu...T4ADSA_enGB400GB400&tbm=isch&prmd=ivns&itbs=1
Post 2003 1150's have a rocker cover with a black lollipop in the middle, if it has ABS it'll have a servo, see initial comment though for non ABS bikes.
ABS or not? Check for the phonic wheel on the front wheel nearside.

Easy Peasy
ABS II i.e. non Servo abs has two square ABS lamps on the instrument cluster one above t'other which when the ignition is turned on should both flash together and continue to do so until you pull away (usually you will hear a clank clank sound this is just the electromagnetic clutches in the ABS unit operating) Flashing alternately with the ignition on but the starter not activated means there is an active ABS fault if they blink alternately after you touch the starter that is a low voltage fault and is usually easily rectified
Integral ABS aka servo ABS has two abs lamps but they are not together and one will blink quickly when the ignition is switched on.
Once it settles to the blink on off, If you pull a brake lever you will hear a whine from under the tank area.
If you activate the brake before it has done a self check the light will continue to flash quickly until you release the brake and it completes it's self checks
There is also usually a sticker warning that brake performance is affected if the ignition is off

This here is very confusing stuff. I´m still wondering about the brakes in my bike. Mine is 02/2002 model STD 1150 with BMW marked pistons. With ABS. So all this what i´m reading here makes me think it´s ABS2. It even makes the clank sound when taking starting to move.
Does I-ABS allways mean it´s a servo? Tried to ask this from my dealer but it seems that they are even more stupid than i am.

Look on your instrument cluster have you two rectangular lamps which light up red and blink on and off together with the letters ABS in both If so you are ABS II
Servo abs and I-ABS or Integral abs are the same thing it is a power assisted anti lock braking system with a VERY high rate of unit failure

Earlier 1150's with Brembo calipers fitted are pre servo......Q.E.D

That is exactly what it does. And i haven´t noticed that it lacks braking power when ignition is off. Brake lever feels just the same with bike running or not.
I have no use for ABS at all. Rear brake is completely useless on gravel with this kind of ABS system.

pre servo abs
hi i have a 2002 pre servo 1150 with abs and i can say it has saved me coming off the bike twice for sure no matter how good you are on the brakes there are times when abs is a must dont even think of buying a bmw without it. would you buy a high spec car without abs ?

Is this the servo-unit?

That looks different than the one in my moped.

If you operate the brake you can hear the servo "whine" you cant mistake it.

This is more like it - If you push either brake lever and hear a motor whine as it builds up pressure then it is a servo.
Personally - I wouldn't worry too much about servos or not. Get the best bike for your budget. If the servo dies then remove it (You'll lose ABS but I don't miss it - in fact the brake response is better on mine with the servo out!)
With the servo bike, you'll also get twin spark pots which runs a smoother than the single sparks, but frankly there isn't a great deal of other differences that would be regarded a big selling point.

Exactly - pull or press the brakes with the ignition switched on and you'll hear a pump whining if its got servo brakes. It will also stop very quickly indeed with just one finger on the lever. The non- servo ones don't do either of those things.
Not sure about that, my 1150RT had servo brakes but was single spark. On a 51 plate.
Quickest and safest way to find out is to unscrew your brake light bulb. Start the engine and pull away, if it has a servo a brake failure light will illuminate as the circuit is broken 
The servo bikes sound like a robot when the brakes are touched. I miss that sound actually!

Jaythro says easy peasy and then tries his best to confuse you. Remember he's Irish, they're like the americans when it comes to talking unnecessary bollox with added on drivel.
Forget all the abs 1 and 2. For simplicities sake lets keep it to plain ABS or ABS with servo brakes.
If it whines when you pull the brake lever with the ignition on it's a servo, if it doesn't it's plain ABS.
You mention you hear a clank when starting to move - this is plain ABS, non servo. The servo ABS doesn't make a sound when starting to move.

Or, just go to the top of a very steep hill turn off the ignition, pull in the clutch and let the bike roll down the hill. When you get to about 40mph or within 6 feet of an obstacle BRAKE.
Then post back on here that it is non servo
.

And if it's a servo let us know what hospital you're in so we can send some flowers.
