RENTHAL 520R1 Chain Kit 13/50: a solution designed for motocross, compact and lightweight. Comprising a 520 gold/black chain and an ultra-light aluminum mud-profiled sprocket, this kit is aimed at riders looking for a simple, robust, and easy-to-maintain transmission in dirty terrains.

• Manufacturer reference: 486363
• Type: RENTHAL R1, pitch 520
• Configuration: 13 teeth sprocket / 50 teeth sprocket
• Sprocket material: Ultra-light aluminum, mud profile
• Chain: Standard quality, non-sealed (non O-ring)
• Colors: Gold / Black

Designed for off-road, the mud-profiled sprocket limits mud accumulation between the teeth, facilitating riding in difficult conditions. The non-sealed chain offers a simple geometry and a lightweight assembly — however, it requires regular maintenance (cleaning and lubrication) compared to O-ring chains to maintain longevity and proper functioning.

Common compatibilities: HUSQVARNA CR 125 (2001, 2008, 2014). Ideal for standard replacement on motocross machines where weight savings and mud clearance are prioritized.
