Actually, I did mention Un-paved before:



My point indeed is"what`s the point of buying an 800 pound ABS-system if you have to turn it off" ;)

I shall have double cream with my humble pie please

If you use the GS off-road a lot then ABS may not be for you as off-road riding does require a good level of skill in terms of traction and feel, which will only be beneficial to your on-road riding.

I must do a course one day...one day, but the 12 is such a hoot on the paved roads (second gear wheelie this morning racing a bloke on a fazer) that why would i need to take it off the road? :)

The LT handles like a barge anyway and when feathering the back brakes to settle the bike into a corner the front brakes came on!

But the brakes on the GS (which is presumably what we're discussing here) don't work like that - they are only linked front->rear not rear->front.

Because of the sheer fun of riding off road of course! It`s a blast :D

I'd quite happily save the 795£.

I have abs BTW....

It costs the depreciation on £795 to own the ABS, as a good proportion of it comes back on re-sale.

From my observations, I suspect an ABS bike holds its value better and therefore the option hardly depreciates at all. It just ties more money up for the period.

Big bikes without ABS seem to lie down quicker.

Some Police forces used to economise by buying non ABS and suggest that highly trained police riders should be safer without it. Not many, if any, do that now as mounties demanded the safety feature. Imagine the claim .... wife said he could have stopped if they had provided him with ABS.

When I was riding a Pan, we tested 6 pot CBS, 4 pot ABS and non-ABS. The difference was impressive. From 60 mph the 6 pot stopped a bike length shorter than the 4 pot and three bike lengths shorter than the non ABS.

Anybody done the same test with an Adventure?
 
A point that some have missed is that on all the servo bikes - you can turn off the ABS, but this leaves the huge force and "on/off" action of the servo. If you ride dirt or gravel, or in snow/frost (like the last week!) the ABS/Servo mix is pretty shocking.

I think that the ABS has saved a tumble for me once or twice - but it has also resulted in me hitting the back of a car when emergency stopping on a rough tarmac surface. The road was not incredibly bad - just the top surface cracked and spalling = hit the brakes, and the ABS cycled = no stopping in time. I was of course going too fast, too aggressive, but then again, that's one of the reasons I have a bike... With no ABS in this circumstance, I would have stopped no problem.

Ideally - and truthfully, I guess that I would have ABS again if I could have NO servo, and default the ABS to be off. Then again - why have that weight and complexity as I know I wouldn't use it.
 
After that experience I decided to test both my reactions and the ABS. I went to a local bit of road that has been isolated by a new road. This stretch of tarmac is almost 0.5 miles long and can only be accessed by riding through a gravel mound, so no risk from other traffic. I marked out a point and then accelerated up to 30mph and did an emergency stop using ABS and marked my resting position. I then switched off the ABS and did the same thing and found I had stopped some 6' sooner. I did not practice, nor did I lock up the front wheel. I went back when cold and slippy and did the same thing and found that my stopping distance without ABS was 2' less.

We've danced around this issue many times, and most people will find that in ideal conditions, when you're expecting it, yes, a fair rider can outbrake their ABS.

It's when some twat pulls out in front of you or a kid runs out suddenly, just when you're waggling your foot awake on a long journey that it can't be beaten...IE in the real world of eveyday riding, not semi-scientific ideal situations.

JMHO ;)

As long as it's not on rough tarmac eh...
Or slippery surface.
Or, god forbid, some dirt!

I'd say that the very time you are waggling your foot back in action - if you grab brakes then it'll be for real, and ABS won't do squat. Slides and wheel lock up are not that evil!!!

Sorry Fanum, but its not as simple as the average highway eating GS'er... Linked brakes aside of course (thats a whole new kettle of fish!).
 
How is it that some people on here think they are gaston Rahier on the dirt or Valentino Rossi on the road.

Now when I started riding bikes way back in the seventies I was taught to ride within your limits and within the limits of your bike.

if you think ABS will give you that little bit of help get if not or you don't like it don't.

I remember when disk brakes started to replace drum and very similar arguments came about.


its a personal choice if you are not happy with it don't get it or get rid of the bike and get one you like.

If the only choice was ABS/Servo/linked or not then I would put risk not having ABS to avoid the rest.
Not tried the LT and never will, but on the 12GS the brakes are only linked via the front brake i.e. squeeze the brake lever, the front AND back brakes come on. Press the brake pedal, the rear brake ALONE comes on. For me, its a cracking solution.

The times I've braked *hard* on the 12GS, it has been stable with bollock crushing power.

For me, who doesn't ride home down deserted tarmac separated by dirt berms, but rather though a hazard stricken London c/w diesel slicks, gravel, potholes, black fekkin cabs - ABS gives you the confidence to 'grab a handful' (nobody throw their IAM beard out of their pram please) which sometimes you have to do.

Well I've ditched ABS on my new GSA, coming in April

Having had 4 BMW's (3 GS's and a RT) with ABS and done 75,000 miles with ABS, in comparison to 1 previous GS1150 without ABS and doing 22,000 on that one.

I guess I can compare between ABS and none ABS equipped GS's.

To be fair on my non ABS bike I never had a drama and had all the situations described already..................tired riding/wet conditions/poor roads/drivers pulling out etc and the bike pulled up each time without drama.

However as Big Kuri describes, I have some scary moments on my Servo ABS equipped GS last year......

Once in Landeck, Austria last summer..........2 up and loaded, I was going through the town at about 30mph and pulled onto a roundabout, when a 4x4 deliberately pulled across my path and entered the roundabout,whilst I was crossing it.
I grabbed the brakes, but didn't realise the tarmac was rippled, so it caused the ABS to cycle.........with the result the brakes let off and I had to take evasive action to avoid the collision.

ABS on a DRY, but poorly surfaced road INCREASED the stopping distance considerably and had I not shot onto the grass, I would have T-boned the 4x4, no doubt about it.

I have also experienced the same as Big Kuri, when riding on dry tarmac, that was super smooth like polished glass (around Trieste). I tried to brake (on a NON Servo ABS GS), coming up to a line of traffic..........no brakes again and shot up the inside of the line of cars.


So IMHO, ABS can be as much a danger, as a lifesaver in certain situations.

Even if you have ABS, you can't 'switch off' and let it do all the work in preserving your skin.

Because 9 times out of 10.............you'll be ok............BUT it can still catch you out.


Am I worried about taking delivery of a GSA, WITHOUT ABS....NO!!

In fact I'm relieved to be getting away from all the complexity and the Servo effect which IMHO is a retrograde step by BMW.

If you don't have it, as a 'fallback' then you have to 'brush-up' on your riding skills, observation and reactions...............which can be no bad thing.

Last year I toured the ALPs with Andy Malton, in July in appalling weather for 5 out of the 7 days.

His bike didn't have ABS and mine did, but he encountered all the same roads/weather and traffic hazzards.

Both bikes travelled at similar speeds and without drama.

I don't know why people bang on passionately about ABS on BMW's so much, as an essential factory fit option and rubbish people who don't consider it necessity.

Is it..........I've spent an extra £750/795 for ABS.........I must justify the cost to myself and everybody else, about how superior my bike is compared to those poor, inferior GS's without ABS

Surely if your dream/must have Jap bike was launched and didn't have ABS...............would it stop you from buying it..............no...........probably not

Taught, TAUGHT!!???you were lucky, we rode faster and faster until we fell off, then slowed up a touch:eek:
 
I can see the logic of ABS being sold as a 'safety' feature but why servo brakes? Anybody can brake hard enough to lock the front wheel using just two fingers on most modern bikes, so why on earth do you need servo assistance? Is it technology for technologys sake?

Also, don't forget that ABS is not about brakes, it's about steering. Braking efficiency is reduced so that you can steer.

The idea of a computer releasing my brakes when I'm screaming 'STOP!' doesn't appeal to me, I've been in that situation before and it's not nice.

I'm with Johnny Boxer, my Adventure is coming without ABS. :)
 
Good point Fanum but for 1 thing. I had a very near low speed panic moment WITH ABS and it nearly caused a collision. Thta is what made me go out and test.

I read an article in RiDE that suggested that you should go out periodically and do a test by getting up to speed jabbing and letting the brakes go until the front chrips so you get a feel for what happens. I do this at the atrt of each season just to get my eye in again.

The problem witih ABS seem to be rough surfaces for cars and bikes, except bike riders tend to exercise more control over teh controls, if you know what I mean.

I shall remain a luddite until I find a system that stikes a decent balance and then I may feel it is worth having. The cost is irrelevant - if it is good enough then I want it, that's why I bought a 4 year old GS for more than a new jap bike!

To ABS or not

Around three quarters of us poll YES. I reckon it is time to finish this subject and move with the times. None of us are really taught to ride. We learn the basics and then perhaps take an advanced course etc.etc. but there is no short cut and only mileage can teach us more and then our reactions become slower ! The important thing is to learn to ride within YOUR PERSONAL limitations - don't be reckless because you have ABS or fully comp cover or huge experience etc. etc. Even the very best of us can be caught out - that is why helmets are compulsory. Roll on some decent weather and we can put our theories into practice; Best wishes, Brian in snow covered France
 
brakes

Bought my adventure with abs & servo, because it was what i could get hold of at the time. Previous gs had abs for the same reason, didn't really want the servo brakes , but soon got used to em & glad i've got them now.
Can understand if folks dont get on with them, but I personaly didnt have any probs adapting to them.The abs only has to save your skin once to pay for its self.
As regards it being no use off road I agree but then again my personal veiw is that if i want to go off road i'll use a dirt bike ,much lighter & more fun off road. And i won't have to explain to the wife how i managed to break it.
