DescriptionRenthal Aluminium Ultra-Light Self-Cleaning Hard Anodized 123U - 520 Sprocket

Product details :

Features

The RENTHAL Ultra-Light 123U crown made of 7075 T6 aluminum combines lightness, strength, and functionality for demanding riders. Designed to shed mud, its specific tooth profile limits chain catches and reduces unnecessary friction, promoting a more efficient transmission performance on muddy or rocky terrains.

Precision machining for optimized concentricity and longevity.
Anti-mud profile designed to facilitate dirt evacuation and minimize losses due to chain/crown friction.
Hard anodized surface for better abrasion resistance and a neat aluminum finish.
Weight reduction through strategic cutouts: reduced mass without sacrificing strength.
Specifications: 51 teeth, pitch 520, type 123U — standard format for motocross and roadster.

Ideal for MX, SX, and enduro, this crown is aimed at riders looking to optimize their transmission's behavior without compromising durability. It is compatible with models such as SUZUKI RM-Z 450 (2026), RM-Z 250 (2026), or RMX 450 (2019) equipped with a 520 chain.

Manufacturer reference: 123U-520-51GPHA — Color: aluminum — Material: 7075 T6 aluminum.
