Upgrade your motorcycle’s drivetrain with the REN​​THAL 150U-520-49GBSI rear sprocket, engineered for riders who want reduced unsprung weight, efficient power transfer, and dependable durability. Designed for compatible Honda and Yamaha applications, this silver rear sprocket combines precision manufacturing with a performance-focused tooth profile for smooth, consistent chain engagement.
CNC-machined construction provides greater precision than stamped alternatives, while the computer-aided ultra-light design helps reduce unsprung weight. The sprocket is manufactured from high-strength, specially enhanced 7075-T6 aluminum, offering a weight advantage over steel while maintaining the strength required for demanding riding conditions. This lightweight construction can help improve acceleration response and overall drivetrain performance without sacrificing reliability.
The REN​​THAL 150U-520-49GBSI also features a specially shaped tooth profile that allows the chain to roll smoothly onto and off the sprocket. This design helps promote longer sprocket and chain wear, reduced drivetrain noise, and efficient power delivery. The 49-tooth configuration is a practical choice for riders seeking a balanced combination of acceleration and gearing performance.
Built with REN​​THAL’s focus on precision and racing-inspired performance, this aluminum rear sprocket is a strong replacement or upgrade for compatible Honda and Yamaha motorcycles. Verify your motorcycle’s fitment and required chain specifications before installation.
