Complete piston kit to rebuild the top end of a Honda XR75. Kit comes with new, 10:1 compression piston, rings, piston pin, and circlips. Choose 0.50mm oversize or 1.0mm oversize from options. Compression is moderately increased from stock pistons, but not high enough to need any modifications to other combustion parts. We are currently out of the 48.00mm piston.
