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
' durability and reliability '
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 .
