I had my Triumph dealer lower the footpegs on my 2022 R3R. On my way home from the dealer, the traction control, check engine, and anti-lock brake lights came on. I turned around and went back to the dealer. They took a look at the bike and did not see anything amiss. After resetting the lights they took the bike out on a test ride and the lights did not reappear. For the first 60 miles of my ride home, everything seemed ok. When I got close to home I made a hard shift into 2nd gear. The rear tire broke traction and all three of the above lights came back on.
I am taking my bike back to the dealer, but am wondering if any of you have any suggestions about what may be the problem.
