There are several reasons why your glasses are vibrating, none of them have to do with the motor. My Fat Boy was way worse than my Street Glide until I found the right combination of windshield and wind deflectors.

 

Absolutely. Too low tech for some I guess.

 

Apparently. I use one that I bought at a whitewater shop about 20 years ago, and I see them at drugstores and walmarts. Just a cord with ends that the earpiece fits into, and the more you tighten them the tighter they grip. Also solves the problem of flying glasses when you look to the side.

 

I wear metal frame Oakleys (halfwire 2.0)with no helmet down here and have no issue. Now at ngiht when I have my plastic frame clear glasses on it's a different story.

Food for thought.

 

Try a half helmet instead of the 3/4 or full types. I have no problem on any Harley with windshield and I wear wire frame aviator glasses.

 

lol.........all it takes is losing one pair of prescription glasses when looking over your shoulder to learn that lesson.

 

Or leaning over the side of a boat and losing your $300 Maui Jims.

 

You'd be suprised on how much buffeting comes from below...get the fork baffle & my glasses ceased shaking 100% when I added fairing lowers. Worked for me, but the glasses strap is my vote for cheapest resolution...

 

Thats what I have found, that prolly 95% of my wind problem come up by the tank. Gonna try the fork baffle next. I sure hope that works. I can hold me knees in close to the tank and knock off a bunch of wind. I sure hope it's that easy.
Kroozeabout.

 

30 bucks for 2 pair of small goggles (clear & tinted) = no more blurred vision.
Btw, I wear Harley safety glasses that are fine up to about 60. Wife gets em free where she works. Trips on the highway, out come the goggles.
