I could only find a post about front end vibration on the RT. But on my F3L I'm experiencing handlebar vibration. The bike tracks straight and doesn't pull one way or the other. The tire pressures are ok in all 3 tires. I didn't see any rocks or anything anywhere. I'm running the stock tires. The vibration is at all speeds and increases on higher speed runs. I had it on a 400 mile trip this weekend and no performance issues. Just annoying. I even took my hands off the bars on an interstate (don't try at home kids) and it tracked straight at 70 mph, with the bars shaking. My dealer said something about it could be a steering sensor. IDK about that. Is this normal? My 2016 F3T didn't do this that I recall. Its not a deal breaker or performance issue, just annoying and makes a guy wonder. haha
