Supersprox SPX Stealth 1489:45

The crowns: 0.7800 kg SUPERSPROX Stealth have a lifespan three times longer than aluminum crowns, without compromising performance. Of course, there are lightweight steel crowns, but they cannot handle the torque. Better than aluminum! Try riding 20,000 miles on a Hayabusa with an aluminum crown or completing the entire Dakar Rally on one crown. For extreme racing, factory teams rely on SUPERSPROX Stealth crowns. Are rivets strong enough? There is no doubt that rivets are the only way to secure such a high-performance crown. We know how to utilize this technology by forging rivets into the crowns. Since the beginning of production, we have never had a single rivet failure. Over the last 20 years, more than 6 million rivets have been used. Drawing and image are non-binding. Technical assessment only. SUPERSPROX is a world-leading manufacturer of high-performance sprockets and crowns. Supplier to most European motorcycle manufacturers and factory racing teams. With extensive expertise in the motorcycle sector, SUPERSPROX has been producing top-quality racing sprockets since 1959.
