Nigusil

Last updated

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.

Nigusil was introduced in 1979 on the 350 cc V35, then the V50 and 850T4. It was also used on the higher performance 850 cc 850 Le Mans II model. From engine 80390 (in Europe) in mid-1980, the Nigusil-plated bores introduced with the second series of the II engine allowed the use of lighter pistons and rings with closer tolerances. These ran cooler than the earlier engine, giving more consistent tolerances and reducing the engine's previously high oil consumption. [1] Nigusil is often confused with Nikasil and some texts use the term interchangeably. [2]

The Honda CX series motorcycles, including the GL500 and GL650 Silver Wing variants, were developed and released by Honda in the late 1970s, with production ending in most markets by the mid 1980s. The design included innovative features and technologies that were uncommon or unused at the time such as liquid cooling, electric-only starting, low-maintenance shaft drive, modular wheels, and dual CV-type carburetors that were tuned for reduced emissions. The electronic ignition system was separate from the rest of the electrical system, but the motorcycle could only be started via the start button.

The Innocenti Mini is an automobile introduced by Innocenti in 1974. The vehicle was a rebodied, three-door hatchback version of the Mini, styled by Bertone. A five-door prototype was developed around 1980, but was never put into production. After having been sold to De Tomaso in 1976, the Innocenti Mini ended up being powered by Daihatsu-sourced three-cylinder engines and continued in production in incrementally updated forms until 1993.

It was never put into production, but did influence other production Ducatis that followed. Both Ducati and their United States distributor, Berliner Motor Corporation, were experiencing declining sales of existing small-capacity single-cylinder models, and sought to create a bike to compete with Harley-Davidson. Berliner Motor was keen to have a model that could win lucrative police motorcycle supply contracts, and that could also sell as a civilian touring bike.

<span class="mw-page-title-main">Motorcycle wheel</span> Component of motorised two-wheelers

Motorcyclewheels are made to cope with radial and axial forces. They also provide a way of mounting other critical components such as the brakes, final drive and suspension. Wheels, and anything directly connected to them, are considered to be unsprung mass. Traditionally motorcycles used wire-spoked wheels with inner tubes and pneumatic tyres. Although cast wheels were first used on a motorcycle in 1927, it would not be until the 1970s that mainstream manufacturers would start to introduce cast wheels on their roadgoing motorcycles. Spoked wheels are usually made using steel spokes with steel or aluminium rims. Cast wheels are predominantly made from an aluminium-alloy, but can also be made from more-exotic materials, such as magnesium content alloy or carbon fibre.
