I said it before, but once again, many thanks. I'm surprised at the number of posts and amount of effort you guys put in to help out a new owner. Your feedback and info has been really great!

Rob.

I love the brakes on my Servo-ABS 12GS and have not experienced any negative issues with them at all. The partial-link feature is great for rear trail braking while charging down switchbacks. BMW did a great job all around with this bike

As many here have already stated they're great.

  • They take some getting used to.
  • They stop like the dickens.
  • You have to be careful about pulsing the brake light as this seems to trip the servos up.
  • The ABS shuts off easily if you feel the need.
  • I seriously doubt all but a marvelously tiny percentage of folks can outdo the ABS system despite many vocal (and ludicrous) claims to the contrary.
  • Yeah, it of course is going to cost more to maintain/fix. The price of progress.

I missed this. Have you any more detail?

I routinely tap my rear brake pedal repeatedly to warn traffic behind me if I am slowing in an odd place, like on a busy interstate (which means daily, on my commute) and haven't noticed a problem...

Emoto that's the difference.

I used the front lever and it made for 'an experience'. Nothing too worrisome, it just cycled the servos fast enough to cheese off the ABS and me. Try it under 'safe' circumstances to get an idea.

The rear pedal (having just put a new guard on the switch) has a reed type switch. Break contact and the light comes on. The amout of travel between light on-off and brake application is considerable (relatively).

Several posted that they dont even bother using the rear brake pedal anymore. I beleive this speaks volumes about how some find the performance of semi linked servo's to be great. Yes they are great at stopping hard with little imput, but how often do you use really hard braking on the street? I spend alot more time using both brakes at varying amounts of overlap to finese the GS through corners. For this reason I would prefer a non linked setup.[INDENT]To much braking at the front can get you in to trouble compared to a linear conventional setup. It is a natural instinct for riders to grab a little to hard on the front lever while suprised by a sudden decreasing radius curve.[INDENT]Think about what freddie spencer teaches, smooth easy use of the controlls. This is why you will never see linked or power brakes on a roadracing machine, not even BMW's rumored moto gp bike.

so you are telling us that you found one rider error that shows a weakness of semi-linked brakes... I can find for you a thousand other rider errors where this setup in fact helps the rider

btw, breaks on a curve, read it a few times in this forum... sorry I find it hard to understand - for me brakes are FORBITTEN in a curve (both for a bike or a car), any CSS-alike school will tell you the same, and after all I don't think the FRONT brake would assist in ANY radius correcting reaction (and no, I DO NOT do it nor I feel it's natural to do it) ...what are you talking about I wonder...

also using the rear brake in normal braking situations is not REALLY needed on ANY bike I know - front is usually more than enough, rear is mostly used as an antidiving measure (that in fact doesn't mean anything for 1XXXGS bikes anyway) and cannot help much braking anyway (again on any bike I know) except maybe give you some interesting stunts (then again a stoppie is still better looking)

I don't question you experience (well in fact I do, but at the back of my head) but you seem to tell us thing exactly the opposite I know them to be

btw, we are still off topic - I think the topic says it all pretty clearly?

Actually, a little front brake in a corner can help pull the wheel further in the direction of the turn. Too much, and the front end will wash out and you'll lowside. Sounds funny, but it's true, just ask any road racer.....

I have used throttle and front brakes simultainiously to get my 750 turned faster at summit point's turn 9. I found it to be much smoother than rolling out of the throttle to get the bike turned in.

...Not to mention the vagaries of traffic. It's a complex tool with a raft of complex features. You may wish to consider any hard rules about their use a bit more studiously.

In a perfect world (a track) you'd perhaps not touch the brakes in a corner because you're line would be perfect and need no adjustment. In my world the pedestrian ignores the "Don't Walk" sign while I'm turning and I stop because I have to.

The no brakes while cornering thing is, generally, advice for newcomers that they are expected to grow out of as they embrace the complexities of motoring on two wheels.

But wouldn't a slight adjustment feather of the front only apply a tiny pressure to the rear (given 70/30) in a linked setup? I would think that would not at all get in the way of the technique you describe or cause any instability. And my understanding is the rear is independant for those that like to drag a little a la Mick Doohan etc.

And that question is strictly "servo" discussion ASIDE . . . that's a different thread!!

Backing a bike into a corner mick doohan style has nothing to do with the rear brake. It is simply stopping so hard with the front that the rear of the bike wants to pass the front.
Applying the rear would cause the bike to squat,therby my goal of compressing the front to aid turning will have been lost.

Steve, thank you for summing it up so succinctly..and you're dead right - the ABS and servo brakes are excellent.
