Product details :

Features

RENTHAL Ultra-Light Mud Resistant Sprocket 123U - 520 (Manufacturer part number: 123U-520-52GYSI)

Designed for demanding motocross and roadster riders, this RENTHAL Ultralight™ sprocket combines lightweight construction with mechanical strength. Precisely machined from 7075 T6 aluminum, it features an anodized finish that protects the surface while enhancing its aesthetic appeal. The tooth profile and targeted cutouts facilitate mud evacuation for smoother power delivery on dirty terrain.

Material: 7075 T6 aluminum, anodized
Number of teeth: 52
Chain pitch: 520
Color: silver
Type: standard, mud resistant

Strategic cutouts lighten the component without compromising its strength, reducing unsprung mass and improving transmission responsiveness. Its mud-resistant profile limits accumulation between the chain and sprocket, contributing to more consistent wear in challenging conditions. Ideal for MX, SX, and enduro, it is compatible with models such as SUZUKI RM‑Z 250 (2026), RM‑Z 450 (2024), and RMX 450 (2019).
