I have been experiencing a shake while front braking between 55-75 mph. The shake disappears when speeds are lower or higher than this. Also experience front end wobble when I remove hands from bar at 40-50 mph. Wobble disappears below and above these speeds. I took to dealer and had them ride and was told more than likely need new rotors and both problems probably not related. Bike is 2014 Roadster and has 13,000 miles. Have been experiencing this for over 4000 miles but just been dealing with it. This seems like low miles to need new rotors. Tire replacement didn't help and I replaced pads just because I had some but same effect. Thinking bout taking bike elsewhere and start with tire balance and go from there. Anybody had this kind of issue and what was the cure?
