No, it just reduces the chance of transfering direct force than can cause flywheel halves to twist out of alignment, "scissor".

Had a long talk with my indie yesterday about this and all the different possibilities discussed here. For mine, he's still convinced something has moved on or around the engine that would allow the vibration to resonate into the frame.
First noticed it about 3/4 of the way through a 2000 mi trip. Was on the highway and after filling up and heading back through the gears onto the highway, noted vibes all the way to 2800 RPMs, every gear. Lotta throttle, little throttle, still there. Does it neutral too (normal, but more now). Over 70ish, pans out and glides.
I don't think (more like praying) mine is internal because on my way to work last week at speeds of 35-45, the motor did smooth out for about 10 minutes, no real vibes except at idle (aka it was back to normal). Rode yesterday, full force vibes. Could it be a tuning issue? Just came off dyno few weeks ago, did it before and after. Indie looked at the mounts, didn't notice anything and stated they should be good with only 20K ODO.

Just replaced my front motor mount with a Glide Pro. My handle bars use to shake like they were going to fly off. Now with the Glide Pro mount it does not shake at all. I tried a couple Harley mounts and some after market ones but the Glide Pro did the trick. Best $100 I ever spent.
