@Jarelj This and your earlier post all make lots of sense but how do you think it transfers to rain and also people leaning on the electronics to spin up the wheel 'drifting' as you can see in the BMW and Stoner on the 1299 Aniversario youtube vids that have been doing the rounds?
Surely in rain conditions the slip/grip ratio of the tyre is completely different and does make sense to use the TC in a higher setting, and similar logic when you want a safety net when purposely spinning up the rear wheel to learn oversteer?
As far as rain goes, completely different situation. The DTC system is programmed with rain settings, which which are Level 7 and 8. 7 would be for rain riding on the track, 8 for rain riding on the street (Caveat: unless they've changed it since the 1199, I haven't checked specifically on that, but that's what the settings were for the 1199 DTC system for rain).
As far as "drifting" on corner exit, the electronics have evolved now to the point where they can use the additional data provided by the IMU to actually allow it without the electronics cutting in to stop it, BUT to still intervene if it gets out of control and is about to cause a high side. That's pretty amazing really, it's part of the new DTC EVO system, debuted on the Anniversario model. However, that's still an advanced riding technique, and the intent of the system is NOT to allow a beginner to "learn" how to do it, the intent is for an advanced rider who already rides that way, and would normally want DTC turned off to allow them to control the slide with the throttle, to leave it on and gain an additional advantage by being even slightly more aggressive with the throttle than they normally would be.
I'll give you an example, we had Jake Zemke out at one of our track weekends last year doing riding instruction. I gave him a Superbike to use as his instruction bike and after his first session on the track he came in and said "Turn all that stuff off, it's slowing me down." That was on Level 1 with race tires on the bike, but it was still cutting in enough that he couldn't "square off" the corner and drift out like he wanted to. Maybe that would be different now with DTC EVO.
If you are not at that level currently, you really don't want to "try" to drift your bike out, you're not going to learn anything. What you want to do is continue increasing your mastery of the basics by being on the gas early and smoothly and a good line, and over time you'll find you can get on the gas harder and harder on the exit to the point that it naturally starts to step out a little on some turns. If you just try to whack the throttle open and get the rear to spin up, you'll just force DTC to go into "You idiot, you're about to high side" mode and instead of getting a Stoner-esque drift you'll get a cut in power and you'll get passed on the exit of the turn by an SV650.
