I’ve got a 2017 low rider all stock except bars and seat. I bought it new and it has always had some vibrations, it’s a Harley so I expect it. About 4K miles it started getting progressively worse. At highway speeds it has a decent enough buzz to put my hands to sleep, and at low speeds it is just plan unenjoyable. Can’t even fell the dyna wobble over the vibs. Took it to a shop and they said the mounts were wore and replaced them but it didn’t help it the least bit, told me it was the way it was supposed to be. On decel it shakes the bars so bad and under 3k it’s terrible but over it’s got a buzz. Only smooth about 90mph. Making me want an m8.

 

Also when doing about 60 I’ve put it in neutral and **** it off and coasted and it seems smooth so all seems in the power train

 

Most of the vibrations on my Wide Glide went away, after I installed new tires. Check your tires for uneven wear and the correct air pressure, especially the front. Just my 2 cents!!!

 

I think I’ll get new tires and see if it helps any they are cupped

 

And motor mounts. Inspect them

 

Aftermarket motor mounts? It seems like some folks experience more vibration with them. If factory mounts I would suspect drivetrain alignment. There’s a few threads on alignment some have found success shimming the mounts but it seems like the shop that replaced the mounts should have done the alignment after installation.

 

Cupped tires, will always bounce down the road. Your bike will handle and feel much better with a set of new tires. You can never go wrong with a good set of Michelin Tires.

 

You need to find a new shop. You brought your bike in with cupped tires and they replaced the mounts.
And you knew about the tires but didn't mention it to them?

 

I told them to service it, they should have caught it when checking tread and pressure. So I assumed it was okay it’s not cupped terrible

 

they told me their wasn’t an alignment process
