Rear Sprocket: 

Stealth Sprocket by Supersprox®. The Supersprox Stealth is about longer life, without compromising weight. Primary goal, to last 3 times longer than an all aluminum sprocket and remain as light as possible. It's about performance and function 1st and last.

Features:

• The only dual material rear sprocket available for both street and off road applications
• Steel teeth last up to 3 times longer than aluminum
• 7075-T651 Aluminum core, lighter than steel
• CNC machined, providing perfect fit on the wheel
• Larger tooth radius reduces chain friction and extends chain life
• U. S. and European Patented
• Perfect for motorcycle applications
• Made using CNC machining processes
• Crafted with precision from reliable materials
• World leading motorcycle sprockets

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 foot pound (ft/lbs), 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 the Supersprox-stealth.

Will a steel sprocket damage my chain.? This might sound like an unusual question, but there's a lot of misinformation out there. When you think about bearings for an example. They`re steel on steel and that works great. Steel on steel is the best combination. So when a dealer tells you steel teeth can damage your chain, ask yourself if they only sell aluminum sprockets.

Are the rivets strong enough.? There is no doubt, riveting is the only possibility for fixing such a high performance sprocket. Supersprox know how to use this technology, forging rivets into the sprockets. Supersprox have never had one single rivet break since starting to produce these sprockets. That's over 5 million rivets in the past 11 years. Its perfect for any bike up to 1400 cc.

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. Whatever your dirt-bike, if you want peace of mind and the knowledge that you have the best of the best, then use what the factory teams and champions use and that's the Supersprox Stealth Sprocket!

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: 

With uncompromisable strength, the 520ERT3 has 25% greater anti-shock performance and a 5% higher tensile strength than the previous generation chain without any added weight. The 520ERT3 is our lightest motocross racing chain used by AMA factory teams such as KTM, Yamaha, and Kawasaki.

Features:

• Solid Bush Chain
• Available in Gold and Black finish
• DHA pin treatment - hard chromium-carbide layer formed on pin surface for exceptional strength and wear resistance
• Special alloy steel with extended riveted bushing anti-kink design.
• SDH pin treatment creates an extremely hard chromium carbide layer on the pin’s surface. The inner core remains soft to absorb shock loads.
• Colour
