I have the links and they still work. Will post them up later.
The 800ss actually came in two variants for 03: 800 Sport and 800SS.
The 800SS had an aluminium swinging arm, a better spec Sachs shock with position sensitive damping, fully adjustable Showa forks, better spec front brake and clutch master cyclinders a la 748 type and 5-spoke alloy Marchesinis.
The Sport was lower rent with a steel swinging arm as per the 620 Sport, non-adjustable Marzocchi forks, a lower-spec Sachs shock and 3 spoke wheels. The engine was the same as the 800ss
For 2004-2005 the SS and Sport designation was dropped to become just an SS. Sadly, the SS adopted the Sport's lower specification
The best of the bunch is the 03 SS.
I have an 03 SS and an 04 Sport. Ducati being Ducati saw fit to equip my SS with a Showa shock though. My Sport has now migrated to SS spec and has all the nice bits including wheels and fully floating cast iron Brembo discs.
Just the job for Minitwins racing.
