PBR Ultra-Light Anodized Hard Aluminum Sprocket 504 - 520
Manufacturer reference: 504 50 LD
Designed by PBR from experience gained in competition, this rear sprocket combines lightness and strength for 520 pitch transmissions. Made from aluminum with a hard anodized treatment, it features a stainless finish that limits corrosion while maintaining a low weight — an advantage for keeping good agility in the rear end.
Ideal for roadsters and sport bikes equipped with a 520 transmission, this sprocket replaces the original part while preserving the longevity and reliability of the chain. Consider it for motorcycles like the YAMAHA R9 (2025), the KAWASAKI Z 500 SE (2025), or the SUZUKI GSX-R 1000 R ABS (2021) when the pitch and number of teeth match. Professional installation is recommended to ensure proper chain adjustment and road safety.
