i think you may be confused on how DTC works, it engages WHEN the wheel loses traction, depending on the mode it kicks in sooner. here is an explanation.
How does it work?
BMW
BMW's S1000RR has the most complex TC system on a current road bike. It has a number of different power modes to suit wet conditions: road use, normal track use and riding with slick tire fitments. In addition, it has a lean angle sensor so the ECU has more of an idea about the actual conditions and situation.
The system has two approaches depending on how far the bike is leaned over. When the bike is mostly upright, the ride-by-wire throttle system allows normal throttle performance, and if any rear wheel spin is detected it then retards the ignition to reduce torque and stop the spin.
But from 38-53 degrees (depending which mode you're in), the system actually reduces the amount of throttle that the ride-by-wire will allow, thus reducing the chance that the tire will spin in the first place.
The dash indicates the selected power mode, and different levels of traction control are applied depending on the selection.The system even acts to prevent wheelies (in certain modes) using the same underseat gyro that senses lean angle.
