Supersprox - Extra-long life Martensitic Steel sprockets
In 2024, Supersprox introduced updated technical characteristics for its range of steel sprockets.
During a discussion at the November 2024 EICMA 'Milan Show', Supersprox supremo DJ Maughfling explained that "companies involved in the sale of Supersprox sprockets and the enthusiasts who chose to ride with our product already know that our sprockets are durable. We are known for the special tooth profile and longer life that the tooth profile provides. We would say that it has been one of our success stories over the past 15 years.
"We have now started introducing new materials into the range, giving us the opportunity to significantly improve on an already good design and to increase sprocket durability and service life still longer.
"There are three key characteristics that allow a sprocket to last longer, and the material that the sprocket is made from is of fundamental importance. For the past 15 years Supersprox has been using S45C tempered steel for the rear sprockets. That material is good in terms of its high yield strength, ensuring that the teeth of the sprocket are not deformed when used on powerful motorcycles. The material is hardened before production, and that has been our standard process over many years.
"The second fundamental to producing a good quality sprocket is the tooth form. Supersprox is well known for pioneering the wider tooth profile. Although it is not always understood, it provides more material at the tip of the sprocket tooth, and that is critically important in reducing the appearance of tooth hooking.
"The latest addition to the technical specification is an upgrade to the use of S45Cm - transformation steel. The steel undergoes a martensitic transformation, via an electromagnetic non-contact power transfer. This creates a crystal-like structure, near to the surface of the material. This method of hardening gives the sprocket a 40% harder structure, with the extra strength exactly where it is needed in a sprocket design - just below the material surface.
"Ours is a market that is always looking for longer lasting and lower cost chains and sprockets, and we are confident that this new Supersprox S45Cm specification delivers. Price and value are as much a function of durability, reliability and quality as anything - first class products that bring real and calculable benefits for the rider.
"If our sprocket lasts 40% longer, the chain life will be extended, and we all understand that the real money in a chain and sprocket set comes from the chain. We know that we will sell fewer sprockets to our existing clients. However, the endorsement that they provide will allow our distributors and dealers to bring more riders to the Supersprox and more riders to their showrooms."
Manufactured in Europe, Supersprox was founded by Roger Maughfling in 1959, and his son 'DJ' has his own 40 years of motorcycle sprocket design and manufacturing to build on. Such expertise is at a premium in these component and reliability sensitive times and is 'baked-in' to every sprocket that Supersprox sells.
