AJS 7R 75.5 Bore Piston

£300.00

DESCRIPTION

Forged , High Compression , Lightweight piston for Standard 75.5mm bore " Short Stroke " 7R ( 1956 - 1963 ) engines made specially for us by Omega Pistons

This piston is sized to be used in 75.500mm Iron Bore or 75.420mm Nikasil Bore. 

This piston may be used in earlier 74mm "long stroke" engines for which the correct piston is not available, but of course the capacity with then be 367cc. 

Standard rings are chrome faced with a case hardened EN39 pin

We strongly recommend the use of a DLC (Diamond Like Carbon) Gudgeon Pin which drastically extends the life of the pin, piston & little end bush. 

Our standard Chrome rings are a good solution in iron bores, but for Nikasil bores, Titanium Nitride (TiN) Coated oil rings are recommended.
