Supersprox Rear Alloy Motocross Sprockets for MX & Enduro Bikes - Supersprox Motocross Sprockets

Supersprox Alloy Sprockets are CNC Machined from a tough 7075-T6 aerospace aluminium and are the best and the lightest aluminium sprockets in the world. Supersprox sprockets are Original equipment on KTM, Husqvarna, Honda (HM) and others. If you have set your mind on light weight, then these are the best you could buy.

Supersprox offers a complete range colours for each bike manufacturer and don’t charge extra for color unlike some sprocket competitors. So there is one quality and one high level finish, that Supersprox have chosen for all of their Alloy motocross sprocket line.

Want STRONGER teeth?

Supersprox have developed several unique products over the past 58 years. They have also pioneered the way forward in technical design. Back in 2004, they introduced a special tooth design that increases chain contact and significantly extends the sprocket life – Its an exclusive feature!

Supersprox offers free Grooves between the teeth, allowing the dirt to be shifted from under the chain and this reduces chain load. All that dirt is abrasive and will prematurely damage your sprockets and chain. You really need grooves on aluminium sprockets, its not an option. So, we treat grooves as standard and don’t charge for them.

Supersprox Sprockets have been used by many MXGP World Champions like Romain Febvre, Jeremy Van Horebeek, Tim Gajser, Iker Larranaga and may other great MXGP factory riders.

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.

UNIBEAR Heavy duty 520 chains are specifically made for motocross and off road riding, offering fantastic performance at an excellent price.
