Supersprox Stealth Rear Sprocket:
The legendary Supersprox Stealth sprocket motorcycle 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.
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 2005/06/07/09/10/11/12/13 Dakar wins.
- Only hybrid aluminum carrier / steel tooth sprocket available for all riding types.
- Pound-for-pound, the strongest sprocket on the market.
- Extremely durable and will outlast the competition.
- Designed for bikes up to 1400cc in displacement.
- Guaranteed - it works as designed or your money back!
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.
It's for your bike! 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. Whatever your bike, if you want peace of mind and the knowledge that you have the best of the best, then choose Supersprox Stealth.

Notes on Chain Type:
- Q4 Sealed Ring - Q4 seal ring and reinforced pin and roller provide superior wear resistance, higher impact resistance and fatigue strength. Q4 seal ring offers less friction, which leads to less power loss, almost half that of standard O-ring chain.
- X2-Ring - D.I.D proprietary X-ring design. New X2-ring design provides 40 percent greater wear resistance and better overall chain life.
- SX2-ring - Slim-sized SX2 ring strengthen the stiffness by reducing clearance between plates. SX2 ring has better wear-resistant performance than SX ring by 30%.
- Quadra-X ring - EK Chains proprietary X-ring style.
- NX-ring - Adopted new NX-ring and lasts 15% longer than ZVX series.
- SRS-Ring - Renthal proprietary X-ring design. The special SRS ring is pre-loaded during assembly creating a spring effect. As the chain wears, conventional O-rings and X-rings lose their seal integrity, whereas the SRS ring is designed to maintain itself during use, keeping a tighter seal against the side plates. This offers increased longevity as the specially formulated grease remains incased around the critical pin and bushing area longer while also keeping dirt, water and other contaminants out.
- RX-Ring - RK proprietary X-ring design. RK RX-ring seals are made from an advanced Nitrile Butadiene composite for maximum performance and wear life. Viewed in cross-section, the RK "RX-Ring" has two lubrication pools and seal points versus the single seal point / pool design of a regular O-ring chain.
- XW-Ring - RK proprietary X-ring design. Uses an advanced design with XW-Ring construction for better sealing that provides extended wear and chain life up to 100% over conventional chains. XW-Ring chains are the best high-speed, extreme heat performance chains available today.
- UW-Ring - UW ring thickness is 50% thinner than O-ring with longer life time.
- DG-Ring - Sunstar proprietary X-ring design. DualGuard sealed ring street bike chain technology where the sealing ring has an 'X' shape - meaning there are two sealing points and two lubrication pools versus the one-sided, single-lip design of a standard O-ring. This sealed ring design type dramatically improves lubricity in high heat conditions while providing lower friction and longer chain life.
- TG-Ring - Sunstar proprietary X-ring design. TripleGuard sealed ring technology where there are three sealing lips and lubrication pools on each side of the ring to maintain top performance in high heat, extreme conditions; the TripleGuard ring type is the best for lubrication and protection.
- Duo Glide (X-Ring) - Vortex proprietary X-ring design. Duo Glide seal design reduces heat and friction resulting in a seven times longer wear life than a standard O-ring chain.
- Tri Glide (X-Ring) - Vortex proprietary X-ring design. Tri Glide seal provides three pockets of lubrication and two stabilizers ultimately reducing heat, friction, and increasing wear life by as much as 10 times over standard O-ring chains.
Note for installing O or X-ring chains: As O-ring chains are wider than standard roller chains, when fitting an O or X-ring chain to a motorcycle that was fitted with a non O or X-ring chain as original equipment, it is essential to check that there is proper clearance of the engine cases near the countershaft sprocket and any other places of close contact. Failure to do so could result in damage to the chain and motorcycle and could ultimately cause the chain to fail.
Note: Image is for reference ONLY, actual product will vary based on fitment and selection.
Some Helpful Tools: Try the Motion Pro Chain Breaker & Riveting Tool or BikeMaster's Heavy-Duty Chain Breaker & Rivet Tool to make removing your old chain and installing your new chain as easy and painless as possible.

DID 520 ZVMX X-Ring Chain:
D.I.D is the number one motorcycle chain in the world. D.I.D chains are used by factory races teams from all manufacturers in race series everywhere.
D.I.D's engineers are continuously improving chain designs in order to handle the tremendous horsepower loads of today's high performance motorcycles. In developing the new DID ZVM-X series, D.I.D focused on "Rigidity." Traditionally, "Tensile Strength" has been the bench-mark to indicate overall strength, but tensile strength is only a laboratory static measurement of a chain's fracture point. Rigidity, on the other hand, is the ability of a chain to withstand the forces that occur in the real world that riders experience. Increased rigidity means better power transfer from the engine to the ground, greater resistance to stretching under load, and overall improved performance that meets the demands of the current high-power bikes and the people who ride them.
- Increased rigidity for better power transfer and greater resistance to stretching under load.
- Overall improved performance that meet the demands of the current high-power bikes.
- Designed to meet requirements of machines bigger than 1000cc.
- Same excellent characteristics of the ZVM chains, but its new X2-ring design provides 40 percent greater wear resistance and better overall chain life.
- Average tensile strength of 8,745 pounds.
- Wear life index: 3500.
- For use on Superbikes; maximum rated displacement 1200cc.
- Weight (per 100 links): 3.59 pounds.
- Includes a rivet-style master link.
Half the Power Loss - Compared with Normal O-ring chains, D.I.D's patented X-Ring construction 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 action of the X-Ring disperses the pressure and minimizes power loss.
1.5 to 2 Times Longer Wear Resistance - Compared with Normal O-ring chains, the X-Ring's four contact points greatly increase 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.

ZXW and RK's Drag Racing Chain 530PRODR are each made for very different disciplines, but both share the same racing technology which provides the ultimate in high performance drive chains. ZXW features MotoGP and FIM Suzuka 8 Hour Endurance technology and has proven superiority by winning 35 first place finishes out of 39 races at the FIM Suzuki 8 Hour Endurance Race. Several features are required for an exceptionally performing endurance race chain. These include:
- Low Friction - The chain must not reduce power output from the engine.
- High Tensile Strength - The chain must be able to withstand the extreme loads of race engines.
- Consistency - The chain must consistently perform during the entire race duration.
- Fuel Efficient - The chain must not decrease the engines fuel efficiency.
All these features are in perfect balance in the construction of the ZXW chain. RK's ZXW series chains are ideal for high-speed, high-horsepower performance applications, large displacement and extended swingarm machines.
Technical Specifications:
- Tensile strength: 9,450 pounds.
- Maximum cc racing: 1,200cc.
- Maximum horsepower: 200 HP.
- Weight (per 100 links): 3.92 pounds.
- Maximum chain width: 20.9 mm.
- Master link included: Rivet type.
RK's XW-Ring seals provides three contact lips and two lubrication pools to protect against dirt and debris, high-speed abrasion, heat buildup and the loss of lubricant under extreme conditions. That's a fancy way of saying XW-Ring seals make your chain last longer. ZXW's chain link configurations range from 120 to 180 links. Available in 520, 525 and 530 pitch and choose from either Gold or Chrome finish. When RK develops a chain with a combined heritage of both drag racing and extreme endurance racing, riders can rest assure that they're getting the best of both racing worlds.
