Or it can also be because the front tire is lifting enough to reduce its wheelspeed slightly. TC will kick in to overcome either.

Might seem like not much was going on to cause this. But what comes next is what can wreck you. The TC kicks in before the tires completely lose traction.
Ahhhh ... I thought it was an audible signal of some kind but he was scraping .. makes perfect sense now! THANK YOU

I watched it twice full screen on Youtube but I cant see what the bike was reacting to.

It is really weird and I can't verify it but I swear my bike wants to wheelie when in second gear and leaning over if I crank it. (ie a city street corner.) I have noticed this a few times but can't reproduce it on demand. Maybe it is something in the shape of the road surface that causes the wheel to jump up or maybe it is my imagination, I don't know.

My Opinion:
Vee or V= DL1000 before 2014
Vee2 or V2 = DL1000 2015 to 2019
Vee3 or V3 = DL1050 2020 to?

My Stroms:
2006 DL650: 202,000 km 125,500 miles, Sold
2012 DL650 139,500+ km, 86,700+ miles. Sold
2015 DL1000 New July 2015 205,000+ km, 127,000+ miles.

This can help preventing from cars pulling out in front of you (SMIDSY)

My RT does the same thing. Because you are leaned over you are not lifting the front of the bike quite as vertical. That makes it easier to "lift" the front wheel. One little bump makes this even more obvious.

Thanks for the validation! I was wondering if I was imagining it and it's nice to hear someone else noticing a similar effect.

Why turn it off? Well, it's the only way you can roost gravel and sand into the face of your buddy riding right behind you! Geez.

Also don't discount the force of your front springs. When you are leaned over your front springs are somewhat compressed from the centrifugal force. You get on the throttle and it unloads those springs, but since they're compressed already you get extra upward force.

You can see this effect on bikes and on cars. Cars sliding in a full 360 degree turn will compress the outside springs, then as they rotate beyond 180 degrees, those springs release that energy and often times the car will simply flip over onto its roof when that energy release combines with the sideways force that is now on the opposite side of the car.

Be particularly careful if you are in an accident avoidance maneuver (swerve), as you get fast compression and de-compression. Say a car pulls out of a side street in front of you, then sees you and stops right in front of you. If you quickly swerve to miss the car, you can really compress your front springs, and if you get on the throttle as they are de-compressing you can easily loft that front wheel without meaning to.

Another scenario to be cautious of is if you start to make a left turn, see an oncoming car, hit the brakes, realize you're already too far into their lane and decide to go for the turn in front of the car. Having hit the brakes, your front end can be almost fully compressed. Then you change your mind, release the brake, hit the throttle, and you will find yourself wheelieing across that road, surprising that driver and yourself.

It's good to practice that though, in a parking lot. Hit the brakes to compress your front end, and hit the throttle as you release. It takes very little power to loft your front wheel when your front springs are rebounding at the same time.

I addressed that when I said "riding normally and not hooning about"....

I normally leave TC off since it is such a buzz kill; I really dislike hitting throttle and having power cut on the slightest wheelie action. And no, I don't go 'hooning about' (well, I don't think so anyway but never heard that word) but now and again like to roll the power on.

Around here we don't have a constant slippery road problem, unless it is just started raining or construction crap on the road. When I am feeling like I want mother looking over my shoulder I will usually bump to TC2 to get max benefit.
