The Sunstar Rear Aluminum 40-tooth Sprocket is engineered for high-performance motorcycle applications, combining strength and weight savings with advanced design features. Crafted from aerospace-grade 7075-T6 aluminum, this sprocket offers exceptional durability and lightness, making it ideal for riders seeking reliable performance without adding unnecessary weight. The computer-designed weight reduction holes further decrease the sprocket's overall mass, enhancing acceleration and handling while maintaining structural integrity. The unique tooth-and-valley pattern increases chain contact area by 24%, ensuring more efficient power transfer to the rear wheel. This design not only improves acceleration and responsiveness but also helps distribute chain impact stress across a larger surface, significantly extending the sprocket's lifespan. The hard anodized coating provides a tough, corrosion-resistant finish that withstands harsh riding conditions, maintaining the sprocket’s appearance and functionality over time. Whether for racing or everyday riding, this sprocket offers a balanced combination of strength, weight savings, and durability. Designed specifically for 520 chain systems, the Sunstar 40-tooth sprocket is a reliable upgrade for riders aiming to optimize their motorcycle’s drivetrain. Its high-quality construction and innovative design make it a virtually indestructible component that supports consistent performance mile after mile. Easy to install, this sprocket is suitable for riders who demand long-lasting and efficient performance from their motorcycle drivetrain components.
