There was another thread on this, but sorry guys I cannot locate it...

Anyway, we discussed the fact that the SS does not have wheelie control.

What's interesting though is that each time I do a wheelie, which isn't that often, but maybe half dozen times, the DTC light lights. At first I thought it was bc the rear tire was slipping, but since this seems to happen every time the front is aloft, I'm thinking it's kind of a peculiarity of the system: it lights, bc of lack of sync f/r but it's doing nothing(?) in this case.

Thoughts?

I think you are correct. It probably detects that the wheels are spinning at different speeds and thus. lights up.

thats the reason...DTC checks wheel spin and engine spin to determine when it needs to control for slip. Usually the front and rear spin at the same rate, unless in a skid. In a wheelie your front slows, the reason for DTC kicking in

Yes, to both of the answers above.

Yes, thinking same...differential spin of wheels... but it's a bit deceiving in this circumstance...since apparently its signaling, but not intervening in any way...kind of a false positive, if you will.

And, we couldn't tell the difference between doing a wheelie with or without rear wheel slip by the indicator. No big deal, just interesting to note that the electronics are dang terrific(!), but not telling a perfect story in all circumstances.

I did a wheelie yesterday and no DTC light came on. Was in sport mode with standard settings.

Interesting, I was also in Sport mode standard settings...

Has your light ever come on?

Hmmm, maybe it did activate on mine...as the roads I typically ride are not the smoothest or cleanest.

I've never done a wheelie in my life, would like to but no idea what to do 😂

Yes it used to come on when I used touring mode when running the bike in, particularly when going over gravel But I don't think it has been on when using sport mode ? but then again I cant remember when I would have needed it and it didn't come on. My power wheelie was a result of coming out of a bend and transferring from the inside smaller part of the tyre to the larger outside giving it a kick as well as a healthy amount of throttle. Traction was good and wasn't feeling any slippage in the back tyre and the bike came down eventually on its own without chopping the throttle. The power was delivered very smooth, maybe this is why the light didn't come on. All I know is it was awesome and if I tried it 10 more times I don't think any would be as smooth as that one>

I suppose now I better test my DTC light on sports mode.

Just whack the throttle open in first from a crawl, and it will happen. Work up to it gradually though; you don't want to flip it!

I did another again today, and light the flickered again. Since I only weigh 133 lbs, and the surfaces I ride faster on are not the smoothest or cleanest, it's possible the rear might be spinning an imperceptible amount each time for me. Be interesting to continue to see inputs on this.

Are you doing a power wheelie or clutching it ? are you lifting the wheel right up i.e. balancing on the back wheel or just lifting the front then powering till it comes down again ? the reason I ask it My wheelie was not an up high balanced wheelie and maybe the DTC comes on after a certain angle of lift ?

Power wheelie in first (no clutch action) by getting heavy on the throttle. Not high, inch or two off the pavement.

Maybe I am losing traction an imperceptible amount...and it kicks in and stops it before I notice.

Also, maybe that's why my tire is wearing faster too, haha. But a guy's gotta have some fun, right? Otherwise, imho, what's the point of having such a bike...

This may explain a little, yes, lol. I'm all for mileage on this set, at least for starts. :laugh:

Ahhhh In first ...... mine have been at speed in second at 8000 revs + and just as you would normally been changing to 3rd, yeah if I were to floor it in 1st I would expect the DTC to kick in, The back wheel would spin loosing traction before the front had fully travelled past it suspension limit kicking the DTC in and when the front comes off it would extenuate it further. I does mention in the instructions that the rider is to manage front end lift lol >

Acelerate slowly to take up the slack in the drive train...then wack it... in progressively larger amounts, until you're used to the throttle/wheel lifting, input/outputs.

Try to make it come up smoothly, not jerking, so there will be minimal drive train stress. And better control, in general.

Most of all, safety first. If you're not comfortable, don't do it!

Thanks again for the advice, just waiting for a dry day here in the UK 🙄
