high polish it appears to me.

I think so too.  Also, I don't think motorcycle makers didn't start chroming rockers until much later. 

Replica of a prototype 750 Sport.  Note the cool paint scheme and the curved exhaust pipes.

I liked this pic.  Are those Desmo rocker arms chrome plated or just highly polished?

What gets me is the bolt used to retain the valve guide...

The bolt was probably added for insurance.  Maybe they had a problem with the valve guides pulling out.  Did you get a chance to read the story behind that bike?

I thought it was a pretty good story for Ducati, sort of like an Australian version of Paul Smart's Imola 200 win in 1972 or Cook Neilson's Daytona win in 1977.  Perhaps that bike contributed to Ducati's popularity in Australia.

It was.  If you can find a socket-head bolt on a bevel Ducati, then it is not original.  All slotted screws and hex-heads originally. 

I can't imagine a bevel valve guide pulling out.  They are in pretty damn tight, but then again, maybe they thought 860cc was the bomb.  Literally.

Travman,

You find the coolest vintage bikes!!!

Good to know.  I know the seat is not orginal on my Darmah and the two bolts that hold that seat on from the underside are the only socket-head bolts that I've noticed.

Thanks, but I'm just derbying what I saw on Bevel Heaven.

If you liked the prototype of the 750 Sport take a look at these pics of prototype 750 GT's from around 1970.  I dig the shorter seat.  It gives the bike different stance.  Notice the smaller tank with graphics and badges similar to previous single cylinder models.  Also, you can't miss the huge 4 leading shoe drum brakes that didn't make it to the production bike.  By that time you needed disk brakes to keep up with the competition.  

   

As most of you would know, I do love me a Moto Guzzi..... but for that ^^  I'll make an exception.

+1 that resembles a piece of farm machinery more than a motorcycle.

the salami slicer next to the footpeg seals the deal

I love the rear, "wind up" suspension!

As do most Guzzi's.

I watched that race and it WAS extra special, it was the only time I saw a Ducati win a race in the 70's !  There were a couple of 750 sports which did ok, about 4th and 10th I think, against a horde of Z1's. We did have a big advantage though, Ducati's were the only marque which didn't have to make a fuel stop. Great days.
