I can't say 100% yes, but when I rebuilt mine I just ordered parts for the 122 without specifying the year (bearings, gaskets etc) and there was no problem.

//edited to add :
Just looked on ultimateparts.net and the clutch cover is the same for all models from 1999-2009

Hi,
have a look on the cylinder, it should be a rotax 123 or mitaka 123 if its been changed.
the model number is quite easy to work out.
if its got a 122 engine in it, then its been replaced at some point,
have a look here https://www.apriliapartsonline.co.uk/index.php/motorcycles-up-to-250cc/rs-125/rs-125-1995-1995.html

you sure it says aprilia on the cylinder?
usually says "aprilia" on the clutch cover (the plastic bit) but will have 122 or 123 on the cylinder (the top bit, metal) with "rotax" being the company who built it. or mitaka if its been replaced.
its all in the wsm or on parts diagrams as listed.
cheers,
