Piston Specification:

 

This piston is designed to be used in ZXR750 engines over-bored to D73mm giving 792cc for Classic TT Superbike rules and events with similar rules. For use with race kit connecting rod length of 103.2mm.

​

The piston crown replicates the valve pocket positions and squish heights (relative to pin bore) of the ZXR750 'race kit' piston with piston diameter increased for a D73mm bore (standard ZXR750 D71mm bore). Valve pocket heights, as with 'race kit' pistons, are designed for use with Kawasaki's race kit cams.

​

The skirt and under-crown is a modern 'slipper piston' design braced across the pin bosses. The skirt is surface finished with a friction reducing coating to aid the break process and promote longevity.

​

Supplied with, rings, pin and circlips. The bare piston offers a 12% mass reduction compared to the 'race kit' piston design, giving a 10% assembly mass reduction. Pin bore D18mm and little end thrust width 18.5mm.
