Replacement piston ring for the Minarelli V1 Polini race piston.
This is a 47mm dykes piston ring that is only for use with the race piston.
Use it on this PISTON.
This does not fit the piston that comes stock with the Polini kit or the stock replacement we sell. This is only for the race piston. If your piston has 2 rings, this is not the one you need.
May fit other 47mm pistons with a single dykes ring though.
