Serria1 has it spot on. In the first 3 gears T mode is in a defuel mode, it shows on dyno runs I have seen. I also run in S mode all the time, I really don't find it touchy though as everyone says. Maybe because my old 2014 Low Rider was so bad. The throttle on that at low speed was literally like and on off switch. I hated it. If you tried to take someone for a ride you would spend all your time hitting your helmets together. As for the second part my front end is still on stock settings, it doesn't bounce at all. That could be anything going on from suspension, to something like a wheel way out of balance or out of round.
