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

Product details :

Features

Renthal UltraLight 518U - 420 (Manufacturer part number: 518U-420-46GPSI)

Designed for motocross, the RENTHAL UltraLight 518U sprocket combines lightweight design with durability. CNC machined in Manchester from 7075 T6 aluminum, it features tight tolerances and an optimized construction for concentricity and load distribution. Its computer-designed tooth profile ensures smooth power transfer to the wheel while facilitating mud ejection thanks to its mud-resistant design.

Material: 7075 T6 Aluminum
Color: Silver
Number of teeth: 46
Chain pitch: 420
Type: Standard / Ultra-light

66% lighter than steel, this sprocket is suitable for riders looking to reduce unsprung mass without compromising durability. Specific surface treatments enhance wear resistance in muddy and demanding terrains. Whether mounted on a racing machine or a leisure bike tackling wet ground, it meets the expectations of riders seeking precise mechanical performance.

Notable compatibilities: KTM 65 SX (2025 - 65 cc), GAS GAS MC 65 (2025 - 65 cc) — check the bolt pattern and thickness for a perfect fit.
