Finally i had time to service my 610 rear shock,and swap it to my 630. Altough specs are the same between those,it should not have been surprise to find out that 630 had 10mm shorter shock. Now bike is leaning a bit too much,since it has front suspension internals from 610 too.... Internal differences are to be seen in future,if there are those exept limited stroke. Unfortunately there is not anything to remove(in 630 shock) to gain same stroke as older. I didnt had them apart at same table,but i believe difference is in bottom damper/seal housing itself.
