Low drag 1275 piston standard size 2.780 +.060" oversize (rings included). This piston has a possible compression ratio of 10.3:1 as fitted to Cooper RSP 1990.

Current pistons differ from the 60s originals and now have a "low drag" slipper skirt design and a shorter lighter 20.6mm wrist pin. Wrist pin height is 1.5276" to crown with a top dish of 8cc.
Performance is enhanced by the use of 3mm oil rings and the smaller drain slot behind this ring decreases the risk of breakage and 2 of 1.5 mm compression rings. Crown depth to first ring is about 10mm.

Piston Fact File
Created: January 30, 2000
Over the years, there have probably been a dozen "stock" 1275 pistons. Currently, three different designs are available from AE/Hepolite as "stock" replacements. All have an 8.4cc dished top, but compression ratios are carried by changing pin height (Pin height is the distance from the top of the piston to the center of the wrist pin- see dimension "A" shown here).
