All are stock compression ratio, unless mentioned otherwise, which makes them ideal in a 'stock rebuild'. Each piston includes one wrist pin and two wrist pin clips. Piston rings must be purchased separately, unless mentioned otherwise. Note: It is advised to check piston to piston clearance in any stock or high performance application. If necessary the rear piston must be machined to provide adequate clearance between both pistons. We recommend Hastings piston rings, which are in fact used by 'The Factory' as well, for all below mentioned pistons to insure maximum life. 57-71 XL SPORTSTER 900CC Standard 9:1 compression ratio. 905281 Std.
