Supersprox® is a true world leader in the production of performance sprockets. With a long tradition of expertise in the motorcycle field, the company has provided the best quality racing sprockets since 1959. Today, it is undoubtedly the largest manufacturer of motorcycle sprockets in Europe, but its passion remains in the production of the technical sprockets, like the Supersprox-stealth. Its products were fitted to the motorcycles of 6 world champions in 2014 and 7 world champions in 2015. The company is constantly looking for ways to become more flexible in production, whilst keeping its high standards. This flexibility allows it to meet the growing diversity in need from customers.

Front Sprocket: 

Renthal off-road front chainwheels are chosen by more factory motocross and supercross teams than any other chainwheel on the market today.

They are CNC machined from a cased hardened and core refined 655M13 nickel chromium steel.

Most models utilize mud grooves which are CNC machined into each tooth on both sides to allow mud to flow away from the key contact points between the chain and the chainwheel. This helps reduce wear and increases the drivetrain lifespan.

Certain models are available in a computer aided Ultralight design to further reduce weight while still maintaining its structural integrity.

Chain: 

D.I.D X-Ring reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers’ modified O-Rings have squashed points that increase friction. The twisting resilience of the X-Ring’s four sections greatly increases its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring. X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain
