Features

RENTHAL Ultra-Light Aluminum Sprocket 518U - 420 (47 teeth) — Manufacturer part number: 518U-420-47GPBK

Designed for motocross, this Renthal UltraLight sprocket combines lightweight construction with precision machining. Made from 7075 T6 aluminum and CNC machined in Manchester (UK), it features tight tolerances and a reduced weight — up to 66% lighter than steel — while maintaining the necessary strength for transmission on muddy tracks. The tooth profiling and computer-aided design optimize concentricity and load distribution.

Material: 7075 T6 Aluminum
Color: Black
Number of teeth: 47
Chain pitch: 420
Type: Standard, mud-resistant
Finish: Wear-resistant surface treatments

Ideal for off-road training and racing, this sprocket fits 420 transmissions. It is frequently chosen by teams and riders looking for a lightweight and reliable part for the rear wheel.
