NOTE: Since many older motorcycles have been modified, be sure to confirm that your engine is still stock before ordering replacement pistons. Using 80" pistons with 74" (3 31/32" stroke) flywheels will result in very low compression and poor performance. Using 74" pistons with 80" (4 1/4" stroke) flywheels will result in contact between piston and cylinder head, and potential engine damage.
