Rear Sprocket: 

The legendary Supersprox Stealth rear sprocket is the only hybrid sprocket available for street, MX, off-road and ATV's. Supersprox sprockets last longer, saving on running costs for your motorcycle, and they can offer a full range of sprockets for most modern motorcycles. Supersprox Stealth will last 3 times longer than an aluminum sprocket and is between 10-50% lighter than a steel sprocket (depending on model and tooth count). Supersprox guarantees that their sprockets will outlast, outperform and outshine the competition or your money back.

The Supersprox Stealth was developed for riding in extreme conditions, where aluminum sprockets can't handle the torque delivered through the chain drive system.Supersprox engineers conceived and developed the combination of the two materials in the millennium year.
Supersprox have counted 12 world titles since that time and in 2005,2006,2007,2009,2010,2011,2012,2013 Dakar wins.

The Stealth is not more expensive than alloy sprockets in real terms. Because the sprocket lasts three times as long, the cost versus life is much lower than that of aluminium. If you put on a high quality chain, don't ruin it with cheap sprockets!

Supersprox Sprockets are used by many top riders like Jeremy Van Horebeek, Romain Fevbre, Tim Gajser,  and may other great mxgp factory riders.

Supersprox Stealth Sprocket Features:

What is the Supersprox Stealth about? Supersprox Stealth is about longer life, without compromising weight. The primary goal; to last 3 times longer than an all-aluminum sprocket and remain as light as possible. It's about performance and function first and last.

Better than steel! Supersprox Stealth is infinitely better than steel! You just can't achieve this level of strength on a steel sprocket with the same weight. Sure, there are light steel sprockets out there, but they can't handle the torque. Pound (lb) for pound foot (lbs/ft), Supersprox Stealth is the best.

Better than aluminum sprockets! OK, this is no contest! Try 20,000 miles on a Hayabusa with an aluminum sprocket or the whole Dakar rally on one sprocket. What about the Baja 1000? These are extremes and factory teams actually buy Supersprox Stealth for these grueling challenges. Don't waste your money on aluminum, invest in Supersprox Stealth.

Will a steel sprocket damage my chain? Kind of dumb sounding question, but there's a lot of misinformation out there. So, think about bearings for example. They're steel on steel and that works pretty well. Steel on steel is the best combination. So when someone tells you different, you should ask if they only sell aluminum sprockets. Supersprox guarantees their sprockets. If they don't do what Supersprox claims, you can have your money back.

Are the rivets strong enough? There is no doubt that riveting is the only possibility for fixing such a high performance sprocket. Supersprox knows how to use this technology, forging rivets into the sprockets. Supersprox has never had one single rivet break since starting to produce these sprockets. That's over 5 million rivets in the past 11 years.

Will a Supersprox Stealth Sprocket fit your motorcycle?

It’s perfect for any bike up to 1400cc. Do you have a powerful 4 stroke or performance street bike? Covering high mileage or road racing, then this is your best option. A single sprocket can last more than 20,000 miles (with correct maintenance). Whatever your bike, if you want peace of mind and the knowledge that you have the best of the best, then choose Supersprox Stealth.

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: 

DID VX3 520 X-RING CHAIN: NOT525

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
