People claimed they vibrated over 70 mph. I never rode one. Would rubber mount offset this?
I am not against a smooth motor. End of long day, I don't need spine rattled at stop. I am past the juvenile fun of it.

Not sure how long youve been around Harleys. And this in not an insult. But those that consider the twin cam as the bench mark sound and feel. Werent around for the Panhead, Shovelhead single cam feel and sound. For me. The M8 goes back to what I feel is Harley. First time I sat on a twin cam i almost walked out because it felt like a Jap bike running. It the Classic Springer look made me buy it. Love my 02. Loved my 16. And had an 05, 08 and an 11. But for me. Pound for pound. The M8 is the better of the 2.

I have enjoyed riding my 2016 SGS. I love everything about this bike except vibration. Im glad Harley cut down on excessive vibrations on M8.
On Riding long days vibration gets to you eventually and is one of the main factors to cause fatigue.
I havent test rode M8 but just reading that they cut down vibrations by 70% is a good change. Once I cross 100k on my FLHXS Ill swap it for M8. Hopefully by then they have new frame and better quality suspension.

The modern twin cam wasnt the Moco first shot at a 2 cam system - one needs to know the history of HD. Honestly & I have a good amount of riding time on the M8 platform heritage & touring line, They are NOT a significant mind blowing up grade - 103 to 107 all i think was done is a bump in Cubes and different gearing to feel more like a big HP gain.......... once you get going & up to speed not a real difference at all. Now, can the M8 platform be upgraded further - Yes, But..... that will cause other problems, That 4 spark plug system is not all its thought to be either, many I know have not changed the top plugs & when they do there a PITA to get out and some have broken causing needed head work.
The real upgrade was the Heritage IMO, 114 & a new suspension, but even the Moco couldnt get that right with faulty fasteners, basically they took the Yamaha star design & incorporated it in to the M8 Heritage.
