Motorcycle crown Spx Stealth 991The motorcycle crown Supersprox Spx Stealth 991: lighter and more durable thanks to its patented technology. Perfect for motorcycle enthusiasts.
- Patented.
- Depending on the model, it is 10 to 50% lighter than a steel sprocket.
- Three times the lifespan of a standard aluminium sprocket under the same conditions and performance.
- Designed for extreme riding conditions, where standard aluminium sprockets cannot absorb as much engine torque.
Better than steel!
You can't achieve this level of strength with a steel sprocket at the same weight. Sure, there are lightweight steel sprockets, but they can't handle the same torque.
Better than aluminium!
Try riding 20,000 miles on a Hayabusa with an aluminium sprocket or doing the entire Dakar rally with one. For extreme racing, factory teams trust the SUPERSPROX Stealth sprockets.
Are the rivets strong enough?
There’s no doubt that riveting is the only way to secure such a high-performance sprocket. We know how to use this technology by forging our rivets into the sprockets.
We have never had a single rivet break since we started production. Over 6 million rivets have been used in the last 20 years.
