usa Stock Front Tire Out Of Balance/Round

[Fog Man]

On first ride from dealer Friday October 23, 2020 I noticed the front tire has a balance wobble (bounce almost) from ~38MPH thru 50MPH. Above 50MPH there is a whirring sound and slightly intolerable higher frequency vibration felt through frame, bars, et cetera.

My research so far only produced that the 2021 T7 comes with a spoke weight opposite the valve stem. I removed the weight rode again, and experienced no change in vibration pattern.

Dealer balanced on a machine, placing weights back into the same factory setting. Followed by claim that this is how the stock tire performs... "this is normal ADV knobby tire vibration."

 

Thoughts? Help?

If you haven’t seen this thread yet, it might give you some ideas to try. An out of balance or out of round tire might be the culprit.

Has been a number of reports of faulty front Pirelli tyres, one guy had the dealer replace tyres twice until the problem went away. After much  mechanical testing amounted to nothing. Whirring is normal for the stock Pirelli tyres, especially the rear. After 1000kms or so, Whirring seems to be less noisy.

 Can you tell us where you saw reports of faulty tyres?
