Nigusil

Nigusil is a patented metal alloy created by Moto Guzzi for motorcycle cylinder liners.

The research culminated with Nigusil, a nickel-silicon alloy applied to the cylinder through special procedures.

This innovation allowed lower friction coefficient in the engine, significantly lower levels of mechanical parts wear, and considerable savings of lubricant.

Treatment of cylinders through Nigusil was also used by many manufacturers, Maserati among them, and generally on racing engines.

It was also used on the higher performance 850 cc 850 Le Mans II model.
