Supersprox Stealth Rear Sprocket In Blue for Yamaha Bikes – Supersprox Motocross Sprockets

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.

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.

How to change your chain and sprockets:

Before you make a start on this job, make sure you are familiar with the technique for breaking and re-fitting a chain’s rivet link, and have the tool to do the job. You will also need sockets big enough to undo the front and rear sprocket nuts, which are often bigger than those in standard socket sets.

1. Make sure you have a clear working space. The first thing to do is place the bike on its centrestand, or a paddock stand, so you can remove the rear wheel when it comes to replacing the rear sprocket.

2. Check if the gear lever needs to be removed before the sprocket cover is removed. Note the position of the splined boss that bolts to the shaft before you remove it. Now remove the the front sprocket cover.

3. Front sprockets are secured with a big nut which can be self-locking, or it may have a tabbed locking washer. Tap back the tabs with a flat screwdriver or punch and hammer. Have a new washer ready for later.

4.You need to prevent the force being applied through the sprocket nut turning the back wheel. Wrap a piece of hard wood in soft cloth and insert it through the back wheel (take care not to trap the valve).

5. When removing the front sprocket nut, use a breaker bar. When you have the nut undone make a note of which way it is fitted, sometimes there is a shoulder on one side. Leave the front sprocket on for now.

6. Remove the rear wheel and lay it flat on the floor with the sprocket facing up. Undo the sprocket nuts and remove. Compare the old and new sprockets for fitment and size. Now fit the new sprocket.

7. Compare old and new front sprockets for fit/size. With the wheel still out, which will make it easier to manipulate the sprocket as there’s no chain tension, fit the sprocket and wrap the old chain around it.

8. Loosen the chain adjusters a couple of turns. This will help when refitting the wheel because the new sprockets will tighten the old chain. Refit wheel with the old chain on, don’t tighten the spindle nut yet.

9. Split the chain, using a splitter tool. Loosely join the two chains together. Pull the old chain from the front sprocket until the new one is around both sprockets. Join the new chain with the riveting tool.

10. Fit the tab washer and front sprocket nut, re-insert the wood into the wheel and tighten the nut to the correct torque setting. Tap the tab on the washer over the nut. Now tension the chain and tighten the spindle.

Please note: You should always replace the sprockets at the same time as the chain. As running a new chain on worn sprockets will cause rapid wear, leaving you needing to replace the chain again in very short order, so it’s a false economy to replace just the chain.
