Has anyone out there ran into this issue.I owned a 2018 GTL and I changed riding mode to dynamic but do not like the backfire noise on de-accelerate. Tried moving back to road but mode will not change. I have tried when bike not moving and when riding. I don’t get why BMW programmed that burble sound into dynamic. I installed Rehmus cans on my GTL a few weeks ago and that noise is even more irritating now.
