Thank you for the quick response. How do I go about recalibrating the torque sensor? Is that something a mechanic needs to do or is it something I can do through the control panel?I had the same problem with one of my 2016 ST2 bikes: Intermittent slowing, sluggishness. The next time it happened I stopped immediately and recalibrated the torque sensor. Problem solved. It hasn’t happened again.
