Fork seals Q

Hey

I have a 97 M900 with marzocchi front end , marzocchi monster seals are 40mm and Showa 41mm from what I understand

But the marzocchi on there are 41mm, anybody come across this?

From what I was told, that year of bike normally was fitted with Showa?

Not sure who told you that ‘97 bikes were normally fitted with Showa forks- my ‘97 900 has Marzocchi’s (albeit now with Maxton internals).

1997 was an odd year for Ducati with a lot of bikes being built with what they had a lot of, hence a lot using the smaller valved 750 heads.

Out of interest, what makes you think you have Marzocchi forks on your bike as they look like Showa’s to me from the photo.

Marzocchi forks on 900 Monsters usually have blue adjusters on the top of each leg.

Have a look for identification markings on the fork bottoms.
They're hidden from easy viewing but on my Showas there is an embossed I.D. marking on the inside of the fork bottoms, just above the lower plastic mudguard clip.
It says .... erm ...... "Showa".

edit ... unless they're Marzocchis, in which case I dunno how to ID them.

Jeff I think I’m right saying your bike is later (2000-ish?) and as you say has the plastic clips to support the front mud guard whereas on the earlier bikes the mud guard mounts are part of the fork bottom.

I am not sure if the earlier Showa forks were marked the same (I did have a pair from a 888 some time ago but I can’t remember now) but certainly looking at the photo the lower part of the slider tube appears to be more pronounced than on my Marzocchi’s and more like the design of the 888 Showa’s I had.

It could of course just be the angle of the photo but as I said- Blue adjusters on the of them will definitely mean standard Marzocchi's.

Ah, yes. My Mistake.
They are earlier, "non-clip" type by the looks.
Mine are later (2000) as you say.

The earliest of the M900 all had non-adjustable Showa forks when new.
Adjustable Showa forks were introduced with the M900S.
As referenced above, by ‘97 Ducati were financially in the mire with parts suppliers withholding parts till paid, so sometimes bikes got “alternatives”.
Also, previous owners sometimes “upgrade” bikes from factory spec. to avoid changing leaky fork seals or whatever.

The early Monster non-adjustable Showas I have are all marked with raised ‘SHOWA’ text on the inner face of the bottom leg castings. Those for 750SS are similarly marked, so have a look at yours if you can?
