Yes, MR12 uses the same piston/sleeve of the RS12 so spare parts are readily available.
Hint and interesting news: The forthcoming Novarrosi engine (previously called Hexagon - Hexagon is the name for the new .21 model who substitutes to the trusty R1) whose definitive name is NS12 uses the same piston/sleeve from the actual engines, all the major changes are on the crank and the crankcase (we will see if they changed the front bearing, sometimes is quite leaky and a fountain of problems).
Aproximated launch date: Ends of May, first days of June. Will try to post some photos of them as I receive one unit.
