I'm coming from a Buell XB12Scg that had a lot of its own vibrations, but I have to say my stock 2020 Fat Bob 114 with 2,000 miles has way more vibration than I expected. I can't believe Harley considers this to be smoother. My hands will tingle after 45 minutes or so. Are there any padded gloves and handlebar bushings and/or bar snakes you'd recommend?

Also, I've read conflicting information. Does the Stage II Screamin' Eagle SE8-447 torque cam add more vibration? I understand valve lift will be changed, but I can't see this adding much more vibration if any.

People aren't talking about a shake or rumble. More like a high frequency buzzy vibration. Like holding a weed eater on full throttle.

I put new bars on my FXBBS and it really helped with vibes. The stock bars are light and flimsy. My new bars are 1.25" and much more solid and heavy. I also switched to poly bushing.

some have claimed that poly bushings make the vibes worse on the new softail’s. 6.5 risers with stock bar and bushings, no vibes here!

Yeah I doubt my reduced vibes are attributed to the bushings as much as the bars. Maybe stock rubber bushings would be even better, idk. All I know is I don't even notice the vibes, now.

The M8 Softail buzz really varies from bike to bike. I got mine under control by shimming the riser to bar interface. I run Biltwell moto bars. I figured it out when I touched the riser and it felt smooth yet the clutch side bar end was really buzzing.
