Nigusil

Nigusil is a patented metal alloy created by Moto Guzzi for motorcycle cylinder liners. The name is an acronym for Nickel-Guzzi-Silicon.

Moto Guzzi, having successfully created the first engine with a chromed cylinder lining, continued research to find a material that could replace chrome. 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.
