I've never seen a head steady on a Ducati, although it's almost universal on other vertical singles. Has anyone done this? Any noticeable improvements?

Re: Head steady?
Guessing because for most of the Duc singles the engine is a stressed member of the frame. Is it not?
It's not a cradle mount like most motorcycles.

Re: Head steady?
That shouldn't make a difference. There are many diamond-framed bikes (those without a bottom cradle) that have heads attached to the frame. For example, Honda CB250RS. A firm attachment of head to frame would tend to prevent it shaking about.

Re: Head steady?
A friend of mine fitted one to a 450 silver shotgun and he maintains it made quite a difference.

Re: Head steady?
I have wondered about fitting a steady , the motors do shake as proven by the difference a rubber mounted float makes,has got to be worth a try.

Sounds promising. Should be easy to do, too - a bracket bolted between a front cylinder/head bolt and the vertical frame gusset behind the headstock.

Re: Head steady?
I think he actually welded a mount onto the central frame bar above the head, but I'll find out from him. He's my friend who had his own Ducati mechanic shop in the seventies and eighties, so I believe him when he say it made a significant difference. I must admit, I've never been totally sold on them on Ducati's as I'd have thought it must be transferring at least some of those stresses to somewhere not really intended to take it (as opposed to the Brit bikes designed with them). My 250 MK3D doesn't vibrate very much once past 3000rpm, and my 450MK3 was nowhere near as bad as I had been expecting. It does buzz a bit in the mid range (and will "walk" on the stand - which the 250 doesn't), but it doesn't rattle my fillings or anything. In fact, I think I find it an almost endearing characteristic!

Re: Head steady?
i dont know of Nigel Lacey is still on this forum.
he would be the guy to say it makes a differance or not . i believe he fits head steadys to his race engines .

I don't think there's anything to worry about regarding undue stresses - we just want to stop the resonance-vibes. It seems so easy to do, even if it's only a small improvement the idea is attractive. Sure, some vibes are nice, but I knew of a 450 owner who regularly wore a kidney belt. Then again, it was a particularly bad one for some reason - other 450s I've experienced didn't vibrate so much. By the way, a funny thing - I was riding my Silver Shotgun when it developed really bad vibrations quite suddenly. When I got home, I noticed the bottom mounting bolt had lost its nut and was almost about to fall out, sticking out several inches.
