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

Product details :

Features

The Renthal UltraLight 518U crown made from 7075 T6 aluminum is designed for motocross riders who want to reduce weight without sacrificing precision. CNC machined in Manchester, it features a tight tolerance and a computer-designed tooth profile to ensure optimized concentricity and load distribution. Its construction makes it 66% lighter than a steel crown, while still being suitable for competitive demands.

Manufacturer reference: 518U-420-46GPOR
Type: Standard, mud-resistant
Material: 7075 T6 aluminum
Color: Orange
Number of teeth: 46 (chain pitch 420)
Universe: Motocross — compatible notably with KTM 65 SX (2025) and GAS GAS MC 65 (2025)

The "mud-resistant" design limits dirt accumulation between the teeth for cleaner chain engagement when exiting turns and on wet terrain. Precise machining and tooth profiling promote a smooth power transfer to the rear wheel while lightening the entire transmission system. Ideal for small displacement riders looking for a race-ready part with the distinctive Renthal orange aesthetic.
