Motorcycle crown Spx Stealth Rst-899Optimize your bike's performance with the motorcycle sprocket Supersprox Spx Stealth Rst-899, lightweight and durable thanks to its patented design.
Patented.
Depending on the model, it is 10 to 50% lighter than a steel sprocket.
Its lifespan is three times longer than a standard aluminium sprocket under the same conditions and performance.
Designed for extreme riding conditions, where conventional aluminium sprockets cannot handle 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 cope with the same torque.
Better than aluminium!
Try riding 20,000 miles on a Hayabusa with an aluminium sprocket or run the entire Dakar rally on an aluminium sprocket. For extreme racing, factory teams trust 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’ve never had a single rivet failure since we started production. That’s over 6 million rivets used in the last 20 years.
SUPERSPROX is one of the world leaders in the production of high-performance sprockets and chains. Supplier to most European motorcycle manufacturers and factory racing teams.
With extensive expertise in motorbikes, SUPERSPROX has been producing top-quality racing sprockets since 1959.
