Complete piston kit for 5-speed model. Kit comes with new, 10:1 compression piston, rings, piston pin, and circlips. Compression is moderately increased from stock pistons, but not high enough to need any modifications to other combustion parts. YOU WILL NEED OUR copper head gasket.

standard bore = 48.0mm
+0.50mm over = 48.50mm
or +1.0mm = 49.0mm

or +2.0mm = 50.00mm
STOP! DO NOT ORDER UNTIL you have your cylinder measured by a professional! To install this you will likely require a bore and hone of your cylinder. IF YOU DON'T HEED THIS MESSAGE IT WILL COST YOU TIME AND MONEY!! This is not a big bore kit.
