IwisChain

Iwis has been producing high performance chains for more than 80 years and are based in Munich. We have been stockists of their chains for over 20 years. Over the years, we have tried and tested many different makes of chain for classic and vintage motorcycles and without any hesitation, we can recommend Iwis as a top quality transmission chain. The vast majority of our customers who have used an Iwis chain before - will ask for Iwis again!

Iwis Superlife

By far the most popular chain is the Iwis Superlife. The Superlife chain is our direct replacement chain for motorcycles which were originally fitted with a Renold chain. This chain is made from high quality quenched, tempered and case-hardened steels and is pre-stretched, with shouldered pins, has a high fatigue strength and excellent wear resistance. All the essential chain parts are available in the same high quality e.g. split links, rivet links and double cranked links.

Iwis Megalife

A relatively new development by Iwis is the Iwis Megalife chain. This chain has all the same high quality characteristics of the Superlife chain and more. It has a special silver coloured coating - the exact technical information of which is top secret. The whole chain has this special coating ensuring that it will not rust. It has special bushes which are sintered which means that it can be run dry or with minimal lubrication. Unlike ordinary chains, minimal heat is generated in use due to the release of lubrication from the bush giving virtually friction free movement. It lasts longer than any standard chain and therefore reduces wear on sprockets. For primary chains it provides a cheaper alternative than changing to a belt drive. It is also no wider than a 'British standard' chain so there should be no clearance problems unlike heavy duty chains that have thicker sideplates.

Iwis produce a wide variety of chains which are suitable for classic and vintage motorcycles including simplex and duplex chains suitable for primary drives, camshaft and dynamo. There are also special chains for applications where a chain will be subjected to higher loading.

In caring for your Megalife chain it is best, as with all chains, to keep it as clean as possible. Although the chain can be used without additional lubrication, its life will be increased if it is periodically lubricated with a synthetic light oil. This chain, however, should not be heated up in chain wax or heated in any other substance because the heat will draw out the impregnated oil from the sintered bushes and a wax cannot be absorbed. In addition, the chain should not be sprayed with a chain wax. If an aerosol spray is used, it is best to use a chain spray that contains synthetic oil. If cleaning is necessary (for final drive chains) it is best to wipe the chain clean with an oily rag and do not use petrol or any product with a solvent or propellant in it. Do not use WD40 or similar product. As with all chains, never aim a jet wash at it or attempt to wash it in water.

Iwis nanochain

New technology from Iwis........

The main feature of this new development in chain technology is a patented surface coating on the bearing surfaces on the basis of nanotechnology, which serves as a lubrication surface and provides a reduction of friction in the chain links. It therefore has an outstanding wear resistance of as much as 50% higher than the Iwis Superlife chain. It also has a a good resistance to corrosion..
