Supersprox was founded in Wales in 1959, by Roger Maughfling. Roger was a passionate enthusiast and loved all things motorised, but particularly motorcycles. He opened a motorcycle repair shop in Mid Wales. Following WW2, parts were in short supply, so Roger began to make his own sprockets for bikes in the shop. Eventually the motorcycle repair shop turned into a small sprocket production factory. The company grew, and the market began to demand higher quality parts. By 1975, the company had its own product name (Supersprox) and was to be found on bikes rolling out of Husqvarna, Maico, Triumph and Norton. Supersprox are now true world leaders in the production of performance motorcycle sprockets, from Aluminium rear sprockets and steel countershaft sprockets to the beautifully designed Stealth Sprocket which mixes the best of both to provide longevity, style and weight saving. Supersprox are suppliers and technical partners to many motorcycle producers inc KTM, Husqvarna, Honda HRC and Yamaha.
Supersprox Stealth Sprockets
What is a Stealth Sprocket?
A Stealth sprocket is a steel sprocket, riveted to an alloy core or centre. This provides the best combination of weight saving and the longevity of a steel sprocket - similar to a floating brake disc.
Are they better than aluminium?
A stealth sprocket will outlast any aluminium sprocket by up to 3 times. There is the extra weight, however the steel section of the sprocket is relatively small and the extra weight is easily outdone by the longevity.
Are they better than steel?
It will last as long as a steel sprocket, but it isn't possible to create the level of strength with a steel sprocket of the same weight as a Stealth sprocket. You may find light steel sprockets, however they will not be as durable or be able to handle the torque produced by modern bikes.
Are the rivets strong enough?
Supersprox have been riveting sprockets for over 20 years, they have installed over 6 million rivets and not had a single failure.
It's known that a Stealth sprocket has covered 20,000 miles and they are used by factory teams in the Dakar Rally and Baja 1000.
