Our 100M Die Cast Pistons are made specially for us by Omega, one of Britain's leading competition piston manufacturers. They have the original 100M dish of 14CC which will give a compression ratio of approximately 8.5:1, providing the cylinder head and block have not been skimmed.

Being lighter and having a better design than the original they are not only stronger for performance use but are also quieter for road use. We have used metric sizes in order to take advantage of the latest ring technology and reduce crank case pressure.

They are supplied as a set of 4 with gudgeon pins to suit standard clamp conrods (gudgeon pins for fully floating rods are available to order).

The size stated is the actual bore size, all clearances have been allowed for on the piston.
