2017 F3 vibration

[Road-Kill]

I believe it is rubber engine mounted--it should be a liquid filled engine mount to reduce the engine vibration.

Then I would have to say it was poorly done.
My buddies Harley TriGlide at highway speed is smooth as was my Ultra Classic.
They are rubber mounted and you could cut a diamond on the gas tanks of both.
I cant say that on my F3s.

It's the engine balance that's "poorly done" better quality mounts would help but they couldn't do magic. Pistons-rods-crankshaft built to tighter tolerance would solve the majority of the engine balance problem--so they saved a few $100 & skipped that part.

With my Vibration Damper and new tires I have very little vibration on my F3. I have rode quite a few 998s that I have worked on and that engine has a great deal of vibration. Their vibration is consistent at all levels of RPM's. My F3 had vibration at specific speeds, which was belt harmonics. After that was fixed, getting rid of most of the rest was achieved by loosing the Kendras...

I had the same experience as Doc on my F3L by adding a vibration damper and losing the Kenda's.

You are Very Fortunate to have an engine that happened to be assembled with parts that have the same balance characteristics. That's why some Spyder owners solve their vibration problems with the belt vibration damper & others still have problems using your same solution. When one spyder can park the bike in neutral & slowly rev the engine in the 3200-3800 rpm range without feeling a vibration----the belt tension vibration damper will solve all the vibration problems. If one feels the vibration while parked with the engine running in the 3200-3800 rpm range all the belt tension dampers--regardless of the supplier will not solve the vibration problem. Unfortunately the only current solution is to ride beyond the problem rpm range. I'm doing 70 mph at 4000 rpm without a problem. My foot vibration isolation pads, foam handlebar grips, & gel seat modification from www.astechseat.com all help reduce the vibration level.
