Description
If you're running high-mileage track days or competitive racing on your Yamaha, sprocket wear directly impacts acceleration response and power delivery. The Supersprox Stealth combines steel teeth that resist wear with a lightweight aluminum core, giving you the durability of a steel sprocket without the rotating mass penalty. This is the engineering trade-off that separates purpose-built racing components from budget alternatives.
The forged rivet construction locks teeth in place under extreme load, while the hybrid design outlasts pure aluminum by 4x—meaning fewer rebuilds and more time actually riding. For 1400cc and smaller displacement bikes, this is the strongest sprocket-to-weight ratio available.
