1275cc Low compression - low drag slipper type piston in standard size for modern day compression ratios and unleaded fuel.  Typically installation will result in a minimum 8.8:1 compression ratio but on some pre-1984 Metro versions it was higher.  Current pistons differ from the 60s originals, improved with a "low drag" slipper skirt design and a shorter lighter wrist pin.

Wrist pin height is 1.4689", crown has 8cc dish, and they have two 1.5mm compression rings and a 4mm oil ring. From the top ring to crown these measure about 7mm and the high compession P21253 piston have 10mm gap from top ring groove to crown. Sold each - 4 per engine required.
