I didn't do it on purpose. I was on a suburban road, the short two lane type. I was driving swiftly, not overly fast. The flat left bend had no visibility, and the road was known to me since I use it on a daily basis. While leanning, at say 30 degrees, a truck on the opposite side, took a good meter from my lane. I grabed the front brake medium-hard and tried to maintain a course off its path. The bike started to lift and lift to the point I almost hit the kurb. Is cornering ABS working properly? Did anyone tried it? Is there something wrong with my bike, or is it something wrong with all Multis ?
The bike will always try to sit up under braking if you're cranked over (as you probably noticed!). Lean angle and brake application are directly related. Sat up, give it max. Cranked right over, give in min/none.... Glad you stayed on! I think the ABS works by sensing front wheel lock and momentarily releasing brake... And repeat, very quickly. If your wheel didn't lock, ABS wouldn't have kicked in.
I had been interested in this when KTM had introduced the system (and while waiting for Ducati to embrace it as well). One of the most informative texts/videos that I found at the time was this. The system cannot overturn the laws of physics. Any bike that brakes in a corner will have a natural tendency to come up straight (or have a quick low-side). The new system tries to regulate pressure in a different way as you can read in the text. So it helps you stop without falling while in a corner and makes the process of coming upright smoother (I assume depending on what pressure you apply on the brake lever). I believe your bike is fine. By the way, it's good to know first-hand experiences regarding this as well as that it didn't end up with you on the ground I wonder if we'll have to keep up with these idiots (trucks on the wrong side of the road) all our lives ....
All ABS will do is prevent wheel lockup, physics still applies and the bike will want to sit up. I though the consensus in these situations is to lean more rather than grab a handful of brake.
That Leanometer looks like an accessory I could use to learn leaning my DVT to its full capacity :Watching:
It is but manufacturers are brainwashing buyers into believing you won't crash if you grab an handful with cornering abs tbh I never rely on electronics, I prefer years of experience and I never cover the brake lever in bends because the first thing your brain tells you to do is pull the lever.
Hello Costi. It is for sure that for the same curvature radius, when you reduce your speed you must accordingly reduce the leaning angle of your bike. In my perspective you suffered what is called "target fixation''. Did you remember if your arms was relaxed? Did you steer the bike? As it shown at the video below, the Multi cornering ABS works perfect but the rider was prepared and not scared. The good news are that first of all YOU and your bike are unscratched.

Sometimes it's difficult to overcome natural instinct when your eyes are a wide as dinner plates and your sphincter is pulsing like the clappers. :Nailbiting:
Yep, that's what advanced training is all about: overcoming those counter-productive 'survival reactions'. No. 1 is target fixation; No. 2 is shutting off and grabbing a handful of brake (especially when leant over) when summat unexpected happens. Combining track-based practice such as CSS with on-road training (IAM, RoSPA etc) is a very good thing to do. And some of the best advice I ever had was, "If in doubt, stick it on its ear…"
A bikes tendency to stand up on the brakes is determinedby the geometry of the bike, head angle, front tyre profile and suspension set up. That's why sports bikes don't do it. I've noticed myself the multi does do this a lot more than I would have expected, I would imagine a lot of this could be dialled out if you got in to the suspension set up properly not just the default set ups. I think for a track day you would pretty much need to play around with this, as I'm bone idle and i can't see me tracking this I probably won't bother
If you really want to see if the cornering ABS is working, how about turning off the ABS and trying a similarly maneuver on the same corner
Need to try on gravel not dry concrete or blacktop. Difficult to get the front to slide on dry blacktop, better chance with the rear.
