Good morning everyone, Once again I need your advice. I originally had problems with vibration on my 2013 ST Ltd. I had the wheels balanced twice. It was nice and smooth for awhile then the vibration started again. So while in Gatlingburg I had new tires put on the front. Once again the ride was great for about 1000 miles. Yesterday I rode about 200 miles and it started again. A lot of the vibration felt like it was coming from the front tires but it also seemed like a constant vibration from under the seat too. I've had it aligned. The dealers keep telling me that's how the ST rides. I would believe them except for the fact mine rides so smooth for awhile then it starts again. Anyone else have the same problem ??????
