Vibration Thru Foot Boards/Handle Bars After 45MPH?

[David's 2018 SGS]

Hello,

1st time user.....
Just picked up a 2018 Street Glide Special, super clean, 26,000 miles on it
Coming off of riding a 2009 classic for the past 12 years....
Have approx..300 miles under my belt.
Noticing a vibration sensation, thru the floor boards & handle bars @ approx, 45mph & up.
getting some pretty good "teeth chatter" as well @ 70 & up
Appears to go away under those speeds. Proper tires on bike, approx. under 1000 miles.
I did by the bike thru my dealer, of which I've used for years, & put the extened warranty on the bike as well....
Any ideas out there would be appreciated.
Thx

If you are picking up a vibration through the floor boards I would have the dealer you purchased it from check the engine front isolator mounts under your extended warranty

Hello
Thanks for your feedback on this one. I will ask them to do that.
Bike @ dealer now being checked out to address a couple of concerns I have.

check to see if the exhaust head pipe is hitting the floor board mounting brackets. look for shiny spots
