My understanding is you can set the throttle map to sport in rider configurable and have the TC set at minimum. I think there are still some limits to wheel spin and lean angle traction with the TC set to “off”. I believe this is what causes the bike to not wheelie.
Sport mode has a more aggressive throttle map meaning less twist will open the throttle faster but has TC on. Road mode has a more gradual activation of throttle control under twist and TC on. Rain mode has TC on and the throttle response is the slowest possible for the bike.
It is a bit bells and whistles.
I have used the rain mode to decrease possibility of wheel spin coming out of corners on wet roads. The rest of the time I leave it in Sport. Road mode is useless. You have to manually engage the Rider mode every time you restart the bike and I find that a PITA.
