Rear Racing brake disk
 

I don't think this topic has aleready been developped here, but I wish to precise important differences between 93 and 94 models for those who are fans of original items ... and the others, of course !!!

I've been facing the problem few months ago, when I restored my 93...

In 1993, the T.8 Racing fitted Magnesium Marchesini wheels with 3 spokes, compare to 1994 always with Marchesini wheels, but with 5 spokes.

... I'll concentrate my short speech about the rear wheel, cause everyone here know that front Brembo brake disks are different between both models ...

In 93 et 94, the disks diameter was similar : 190 mm,
the number and design of holes in the disks, as well .

However, the thickness was different :
- 93 : 4.1 mm
- 94 : 3.6 mm

But the major difference concerns the distance between the 3 screws (only!!!, not 6 like road bikes ...) to fix the disk on the wheel :
- 93 : 90 mm
- 94 : 68 mm !!!

At the first look, both look like quite similar, but aren't !!!

To be as complete as possible, here are the Ducati references from the original spare parts catalogue :
- 93 : 492.100.11A
- 94 : 492.401.31A

If you're interested, have a look to the following pics !!!

QUERY : I'm currently looking for a 94 disk as spare part ...
