PBR Ultra-Light Aluminium Hard Anodized 504 - 520 SprocketRef : PBR00309A / 1075417005

PBR Ultra-Light Hard Anodized Aluminum Sprocket 504 - 520 (Manufacturer Part No: 504 45 LD)

Designed by PBR from experience gained in competition, this sprocket combines lightness and strength for 520 pitch chain transmissions. Its hard anodized aluminum construction offers a stainless finish that limits wear due to abrasion while maintaining a low weight, which is appreciated on the road and in sports use.

• Material: ultra-light aluminum, hard anodized for better surface durability
• Number of teeth: 45 teeth — suitable for 520 setups
• Color: stainless (anodized appearance)
• Type: standard, precision machining according to PBR tolerances
• Practical advantages: corrosion resistance, reduced friction between chain and teeth

Manufacturing adheres to a strict specification, and the use of carefully selected raw materials ensures consistent quality. By reducing the mass of the sprocket while maintaining a robust tooth profile, it contributes to a more responsive rear end without unverified technical claims.

Ideal for roadsters and light builds — common installation examples: YAMAHA R9 (2025), KAWASAKI Z 500 SE (2025), SUZUKI GSX-R 1000 R ABS (2021) — be sure to check the pitch and number of teeth for compatibility with your motorcycle.
