Renthal 520R1 14/52 Standard - Ultra-Light Self-Cleaning Rear Sprocket Chain kitRef : RT00301A / 3042824

RENTHAL 520R1 Chain Kit 14/52 Standard (manufacturer part number: 485381) — a set designed for motocross use, delivered with an ultra-light mud-resistant sprocket and a bi-tone gold/black chain. Designed to equip 450cc machines like the KTM SX, this kit combines a 520 pitch transmission with RENTHAL R1 design suitable for muddy environments.

• Sprocket: ultra-light aluminum, mud-resistant profile to limit dirt accumulation and facilitate removal during rides.
• Chain: 520 pitch, gold/black color, standard quality (non-sealed), non-sealed links — regular maintenance and lubrication recommended.
• Ratio: 14-tooth front sprocket / 52-tooth rear sprocket (14/52), standard fit for motocross.
• Type: RENTHAL R1, designed for off-road use requiring maneuverability and mounting durability.

This kit is aimed at motocross riders looking for a lightweight and easy-to-maintain solution, especially on muddy terrain. Note: the non-sealed chain requires more attention to lubrication than sealed models. Compatible with popular models such as KTM 450 SX-F (2012), KTM 450 SX RACING (2006), and KTM 450 SX RACING FACTORY EDITION STEVE RAMON (2005).
