Complete piston kit to rebuild the top end of a Honda XR75. Standard bore on the 4-speed mode was 47.00mm. 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.
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.
