yes, but they are interchangeable. don't use original KR1 piston's !
goolge them and you'll spot the difference immediatly.

main differencen : ring-peg on S-piston's is covered by the rings who prevent if from comming out. KR1 rings go half under the peg, and the peg could come loose and hurt you cylinders badly.
My ultimate goal is to die young as late as possible !
