Anyone ever have a vibration from the rear that feels like you're running over road grooves but it doesn't stop? I need to replace the rear tire but have never felt this before. Finally parked it in the garage as it seemed to be getting worse. I run Metzler M880 tires and the rear is in need.

 

you didn't say what model bike, some have a damper on the rear drive pully that are known to fail. just a thought.

 

It's a 2003 Ultra. Thanks.

 

How's your torque on your axle nut check it . It mite need torqued to right spec .Check the cheap things out first.
