kit?

noticed a couple of plates at bottom of shock that dont look factory, they had drs stamped on them. anybody seen them before?

which one is the updated version? What distinguishes the new one from the old one? is it the material on the friction plates? I noticed the solid friction plates are those the new ones? Which should I get for my 2000 RSV Mille? I have Engine # 69XXXX so I don't need to updated the pressure plate...
