Ducati two valve belt drive book by Falloon is the answer to all your questions about that.
But my 85 F1 has a 280 mm fully floating rear disc.
With a outer disc wich is originally made from a gold coloured metal, does anyone know what kind of metal that is?

The "dual line font" for DUCATI you describe was designed by Giorgietto Giugiaro (Italdesign) and is accordingly described as the "Giugiaro Ducati font" by some Ducati fans. (me anyhow!).

The Giugaro font was introduced in 1974 on the new Ducati 860 models (the 1974 SS still had the earier font) and continued until 1985 with the first 750 F1. It was superceded in 1986 with "Ducati" then being written in lower case "Cagiva" style font on all new Ducati models - including the '86 F1 & Montjuic.

It is the Giugiaro font on the "1985 750 F1" (the last Ducati to wear it) that is the hallmark that identifies this bike as the last in a long line of Ducatis that were created under the direction of Fabio Taglioni.

From 1986 all Ducatis were created under the control of new owners - Cagiva.

Does anyone know the difference between the various models in regards to the rear shock? My '86 had a very non-descript, gold anodised unit fitted with a black spring & included a schroeder valve for air pressure adjustment - does anyone know what brand this is?

Both 1985 and 1986 750 F1's, and the Bimota DB1 all had Marzocchi PVS 4 rear shock, which you can still buy from Steve (this Forum's moderator) at Loudbike here: http://tinyurl.com/3tvdgl9 - (Hi Steve!)

The Montjuic, Laguna Seca and Santamonica all had a better spec Marzocchi rear shock (although I do not know the model number) with adjustable damping instead of the F1's air adjustable shock. Although, Cycle World back in the day said you could set the shock to one of the following 3 settings; Soft - which was useless with no perseptable damping, Hard which made the suspension rigid, or, Intermediate - "which allowed the rear end to work better, if not perfectly."

If I am not mistaken the standard F1 and the specials ( Laguna Seca, Montjuich) had different length shocks. Maybe because of the different wheel sizes in the rear. 16 or 18 inch. Good luck, Lou Saif

The photo posted looks like the unit that came off my bike, but the part number listed is different:
according to my parts book it should be 067059100 - the one listed by Steve is 067559100 (it looks the same). Does anyone know what the difference is, or whether there was part number update?

Here is a note from Ian Gowanloch regarding the shock part numbers. (See updated description on the pictures in earlier post.)

hi Mike,
The shockabsorbers come out of a big box that I bought from Ducati Meccanica. On the box and on a few of the shocks is written 067059100.
It has always been a problem with Ducati determining what is an original part. I have a lot of bags and boxes of bits, all from Ducati, That have a collection of parts in them, perfectly interchangeable but not identical. A bag of bolts, half bright zinc and half black, that type of thing. It often leaves me wondering just what the original specification was. The 1985 shock was different, 067559100, but is interchangeable. The later shock was a better article.
Thank you for the input.
regards
Ian
