Friction-reducing Supersprox-stealth sprockets
Supersprox has introduced a new range of chain friction-reducing Supersprox-stealth sprockets for BMW OZ applications.
Working with the BMW Motorrad World Superbike team (Shaun Muir Racing Ltd.), tests are being carried out to help reduce chain overheating problems and premature sprocket wear during the hot summer season.
Supersprox CEO DJ Maughfling says: "The existing 7075-T651 material that is used for racing sprockets has been on the limit of durability for several years, and teams racing at this level are looking for alternatives." Typical difficulties for the teams are identified as excessive and rapid wear of the teeth, deformation of the sprocket material from high torque and overheating of the chain that can be caused by the high levels of friction between the chain and sprocket.
Supersprox has been supplying steel/aluminium hybrid sprockets to teams in endurance road racing for several years, with progressive success. "There are several factors to consider with this type of application and we are very enthusiastic to support teams in World Championship racing, because it helps us to better understand how the sprockets perform under extreme load.
"We will be taking this knowledge to the sprockets we offer our clients for applications such as track day and amateur road racing."
Supersprox replica sprockets for BMW applications are Supersprox number #7091, with the sprockets for amateur enthusiasts almost identical to the race team parts.
