Product Details

This Athena cylinder kit features a 47.6mm bore, giving you a 70cc displacement increase over stock. It uses a flat-head piston designed for this specific application. The cylinder itself is coated with motor-nicksil, a nickel-silicon blend developed by Athena that offers a smooth surface for better piston ring seal and excellent wear resistance.

The 10mm pin bore on the piston is a key measurement to ensure compatibility with your connecting rod.
