Strange ABS gremlin

Sometimes when I grab the front brake, it feels like the lever is stuck open; it takes a second before I can squeeze the brakes. It has startled me a couple times while braking before turns. No chance of crashing or anything serious, just a surprise. I'm not braking real aggressively; I'm just applying gentle pressure to scrub off a few MPH before turn in.

Haven't tried riding with the ABS deactivated. Maybe I'll try that the next few days. I haven't talked to the dealer, yet. It only happens once in a great while, so I don't think about it much.

Just curious if anyone else here has had the same experience.

2013 F8 GS, by the way.

I have not heard of that problem before ...

Since bike is under warranty, I'd sure have the dealer look at it so that the issue is logged. Using either the BMW diag. box or the GS-911 the brake system can be bleed, ABS controller cycled, and then the system bleed again to insure clean fresh bubble-free fluid everywhere.

I would like to "assume" (yeah I know ) that a good dealer would want to do that as a baseline first-move to address your concern.

Does this happen only when braking on bumpy or rough surfaces? If so, sounds like the same ABS issue that has been widely discussed here and elsewhere--basically, the F800GS ABS seems to be very sensitive and kicks in when braking over bumps, even though the wheel is in firm contact with the ground. The feeling is just like you describe, with some lever pulsing. Happens to me a lot.
If not, good luck

Mine does it too. A bit unnerving for sure.

It certainly does it often over bumpy terrain. If it's that sensitive, it might just be sensing a little slip from the front tire if I counter steer it too quickly.

Thanks for the input. I think I'll have the dealer check it out next week just to be sure there isn't something sticking.
