So as with most vibrations, it can be difficult to pin point when the vibration started or did it just get gradually worse until you became aware of it. With my 2016 Audace, I noticed it as my rear tire was approaching it's time for replacement at 6500 miles and I assumed the vibration was due to the worn tire. It was most noticeable between 45 to 55 mph and felt as if there was a flat spot, it is more of a hop than a vibration, like if the wheel had bent from hitting a pot hole. So I changed the tire with the same model that was on it, a Shinko 777, and the same hop, wobble or vibration was there only it seemed worse with the new tire. It's definitely coming from the rear, I don't feel anything through the handlebars, and there is no movement of the front forks. I had not balanced the previous tire and thought that was the most obvious source, so I bought a balancer, balanced both front and rear tire with no change. Then I thought maybe the rear shocks were not properly adjusted. If the damping valve was open too far and springs were too soft this could result in the suspension "bouncing" so I firmed up the spring setting and tried various settings for the dampening valve with no change. Can anyone tell me whether the rear wheel hub is supposed to be balanced to the rear drive assembly and when I changed the tire, I possibly reinstalled it in a different location, out of balance? I plan to remove the rear wheel again, re check the balance and also check if the wheel could be bent. Any thoughts or suggestions are always appreciated. Thank you all!
