Yes, STD is for standard or stock OEM bore size. For the banshee, that is 64mm unless you have some other pistons in it. For instance, the 66mm Blaster pistons used in the long rod setup. The piston will say STD but the bore is NOT 64mm. Just know what you have and you are all good. Brandon Quote Link to comment Share on other sites More sharing options...
