RENTHAL 520R1 13/48 standard chain kit - ultra-light mud-resistant sprocket (Manufacturer reference: 484394)
Designed for off-road and motocross, this RENTHAL chain kit includes everything essential for the rear transmission: a 520 chain with a gold/black finish, a sprocket, and an ultra-light aluminum rear sprocket with a mud-resistant profile. The R1 type and "standard" quality meet the expectations of riders looking for a reliable and lightweight setup without sealing elements (o-ring chain), making it ideal for muddy outings where debris evacuation is crucial.
Recommended for motocross machines, particularly compatible with YAMAHA YZ 450 F (CJ21/CJ22/CJ23) models from 2017–2019. Ideal for riders who want to reduce unsprung weight while maintaining a racing look with the gold chain and black accents. Please check the exact compatibility with your motorcycle before ordering (sprocket/crown ratio 13/48 provided).
