A '93 900ss, a couple KTM LC8's...
How many miles on your bike, Lew? The only other "New" Ducati I've ever ridden was my '04 749 and that bike ran smoother and shifted
way better at twenty thousand miles than it did when new.
BTW, my KLR vibrates more...
Hi Chuck!
I have a thousand miles on my bike and it has loosened up just a bit, but as I think I said, everyone's different. Having ridden since 1964 and been accustomed to what really "manly vibratory action" is like, there's barely a modern motorcycle I ride that feels unacceptably vibey to me. Maybe a KLR would change my tune
The last four cylinder bike I had was a K1200RS, and that was sewing machine smooth (if a Singer on steroids) by comparison to the MTS; no Ducati I have ever ridden could compare to it. My GS had fewer primary vibes (than the Duc), but had the expected rocking couple from the offset pistons and the torque reaction (of course). It was smoother than my MS12T overall, but not enough to comment on, a different feel entirely. My counterbalanced Aprilia (Rotax Caponord) is distinctly smoother (and much more like a Ducati, but less fun to ride), however, I'd say my old Mille was fairly comparable in general feel although it was piped and chipped and made way more noise (hence also perceived vibes) , but I'll say my Ducati falls well within my range of acceptable. As you say, I do expect it to run even better as it breaks in.
I have not shot for a fast break in. If I had to select, I'd actually prefer "a little smoother" to "a little faster," but break in rituals are somewhat religious in nature, huh? . Mine burns no oil, runs well and I do expect it to smooth out and run even stronger with more with miles, but new as it is, I find it comfortable, no tingles and can ride it all day without feeling beat up. It doesn't leave a trail of parts behind itself

(you had to be here in the sixties to understand what that was like) and at this (early) point I consider vibration to be a non event.
If it gets better....GREAT!

I wouldn't buy a big, (relatively light flywheel) high performance twin like this expecting it to match a counterbalanced four, but there's no problem here, and the vibes it does have seem low in frequency, not buzzy. I think "frequency" counts as much as "amplitude" in how I read a bike's smoothness.
Maybe mine is just a good one in this regard. It doesn't strike me as particularly strong running compared to the demos I rode, but they all had more miles than my bike. My bike is in no way slow, now.
I have not owned a new Japanese four banger since 1982, so my experience with counterbalanced Japanese fours is non-existent. I'm sure they are smoother, especially in the normal working range, however, a 90 degree twin is in inherint good balance; it is a function of the design and firing order.
I just don't read most Ducatis as having a vibe problem, but each person needs to judge for themselves.
