I haven't been able to recreate the problem. It seems its the bump plus a number of other odd factors.I note there are already reports of the F800GS having the same problem. I think from memory the posts referred to journos experiencing it. The F800GS also has the electrical cutout problem that has been running on the F800 for a couple of years now.In all of my riding I've never had the ABS come in except when I want to have it work by braking ridiculously hard at low speed to make it happen to demonstrate it. Even when riding hard and braking hard I've had no ABS kick in. So the only time the bike has taken control of the braking is to release them when you're wanting to stop when there is no chance of a slide or going over the front. In these instances the rear wheel was not near locking up or near lift off, its just that the bump or dip fooled the bike and voila! no brakes.((And for you Alex, I wonder if BMW will install this amazing feature on its new bikes..  hang on word has it they've now installed it in the F800GS. I wonder if the 650GS will get it. Of course if a rider dies as a result of this feature there will be no comeback to BMW.  🙄 :wink:))I guess what is of concern at the moment is that riders aren't being told about the problem. So when it happens for the first time its @&$^# scary. I think having the awareness would be better. Also when it does happen, you go into the dealer and the usual response seems to be "we have never heard of this problem before - there is nothing on our system about it etc etc".This problem is too serious to ignore. At present BMW have not got the message of how much of a problem this is. There is a guy on the F800 forum who took his F800ABS bike and traded it in for a non ABS bike losing $3000 (US$ I think from memory) because BMW said they couldn't disable the ABS and he had just experienced the loss of brakes. His argument was he'd rather do a pile of money than injure or kill himself.It's interesting to note that where the problem on the bike was effecting sales (the front pulley and jerkiness) BMW responded quickly, where the problem doesn't effect sales but has been responsible for at least one crash or could injure or kill a rider that BMW TAKE NO ACTION.This kind of reminds me of the tobacco companies when they had the research that smoking kills and hid it. If a rider rides off the road on an F800 because of brakes, and dies, no one will ever know.Personally I Find BMW's way of denying the problem in the face of many claims, alarming. So the next step is to collate that information and try BMW Germany direct. I know in the UK they are talking of going public because of BMW's refusal to neither fix the problem nor acknowledge it.It can't be that hard for BMW to advise riders, or provide a switch to kill the ABS. These should be a minimum. Other than that I think the F800 is potentially a great bike, handles well, goes well, economical (how do they do that), comfortable and a joy to ride on long trips for both rider and pillion. If I was replacing the F800 I think I'd want an F1000.

I guess what is of concern at the moment is that riders aren't being told about the problem.

I haven't heard of an electrical cutout problem, but there has been a stalling problem on the F800GS and the F650GS. Most cases seem to have been solved with software updates.So far I've had over 3000 problem-free kms. Long may it continue.

Hi Artig, so I'm guessing you have the 650GS. That looks like a nice bike. Good luck with the bike and check out the F800riders.org forum. They have a lot of useful information on all sorts of aspects of the bikes.If you jump over to F800riders.org you'll see the cutout problem (yes actually stalling) when decelerating and pulling in the clutch is still ongoing even after the software updates. Not only that but the F800GS is now under recall in the UK for the same type of problem. This is the same problem that has been around for 2 whole years on the F800. I had the bike do the cut out just a few nights ago. I've had so many updates that I'm in danger of having the bike run out of space for updates and then of course it’s an electronic component replacement at great expense.There are also reports of the F800GS experiencing the loss of brakes with the ABS fault.Honda and Ducati apparently do not experience this loss of brakes. Forum members have been in touch with Bosch and Bosch advise that the performance parameters of the system are set by BMW and once the box leaves them they have no control over what BMW set up. Bosch (from memory) was not aware of the problem.Having said all of the above I still enjoy my F800 and would struggle to think of another bike to replace it with except for the F800GS. I think it's negligent not to tell riders that this event exists. BMW should let them know so that when they experience it for the first time they will hopefully be in a better position to respond to it.It's time to collate the info and send it to Germany direct. I know forum members are talking about going to the press. I'm not really into the publicity thing. I just want the brakes fixed.

Artig,It's not a stall. To me you stall when you are about to move off. The event that occurs is the bike is moving, you brake to slow and pull the clutch in to change down and the bike switches off as though you've turned the bike off then on again so you have the lights up. The first time I had this happen I slowed from over 100kmph for roadworks that had a 30kmph sign, before I got anywhere near the 30k's the bike had died so I guess I would have been doing around 60kmph, it was about 5 in the morning so I saw the display light up. I knew what it was because of the F800 forum. So I just started the bike up while rolling and carried on. If you call that a stall then yes it is a stall otherwise it's cutting out. It's really funny when you think about it because it's if you were planning to come to a stop and hope off the bike it's like the bike intuitively makes a decision to stop in advance. I've never had it occur at the wrong moment. If you check out the forum some of the guys have. I guess lane splitting up to a set of lights then just before you get there having the bike die just as the lights go green you would end up with cars shooting past you. Or slowing for a corner only to find the bike is no longer running. I guess it could be a problem. Since it's never been for me I just put it in the idiosyncrasy feature file.

I hadn't been on the F800 forum for many months so lost touch with what was happening. Having the bike cutout in the middle of a roundabout would be a problem. Imagine if it was peak traffic on a big roundabout. That would be an interesting experience.I don't understand the technical ins and outs but it seems to me that a bike cutting out should be an easy fix.
