DescriptionRenthal Ultra-Light Self-Cleaning Aluminium 518U - 420 Sprocket

Product details :

Features

RENTHAL UltraLight 518U Sprocket - 420 (48 teeth) — Silver

Designed for the terrain, the Renthal UltraLight 518U sprocket is CNC machined in Manchester (United Kingdom) from 7075 T6 aluminum. Its precision manufacturing and mud-resistant profile limit dirt accumulation and facilitate drainage during motocross outings. The tooth profiling is optimized for efficient power transfer between the 420 chain and the rear wheel, while reducing rotating weight compared to traditional steel sprockets.

Material: 7075 T6 Aluminum, CNC machining
Color: Silver
Number of teeth: 48
Chain pitch: 420
Type: Standard, mud-resistant design

The 518U is aimed at motocross riders looking for a lightweight and durable sprocket, suitable for 65 cc bikes such as the KTM 65 SX (2025) or the GAS GAS MC 65 (2025). Reliable in muddy conditions, it offers an interesting compromise between longevity and weight reduction for training and racing.
