I have 2 Showa adjustable forks, circa 2001
1 from a m900 sie
1 from a 900ssie
Are they the same inside?
Just wondering before I sell one and rebuild one

When you rebuild, would you share what you did, parts used and where obtained, and any other pertinent info?

Not a pro, but anyway ....
Are they 41 mm or 43 mm inner legs?

Also parked due to having been T-boned on track.

Not necessarily the same.

Are they the same length externally?

The ss housing is longer to provide for clipons

Well,

if both are 43 mm, and both are adjustable, then they are similiar inside, but the total and relative lengths of the cartridge tube and cartridge rod are different.

And they indentically limited as far as function / performance is concerned (though better than the non-adjustables).

All the Showa valves are basically the same...restrictive.

Racetech will be your friend, but their recommended stacks don't necessarily work for everyone.

I've got a set of long forks that must be SS units, came off an '01 M900S oddly enough.
They're shorter travel compared to the Monster units.
Nice for above-the-triple clipons.
They'll suck for tubular bars.

So after all my exhausted research, looks like I’m going the way of total cartridge assembly replacement.
Have to decide which 1 of 3, Andreani,Axxion, or race tech. Have pricing for 2 of the three, will be contacting race tech for theirs
