This package combines a 520 R1 chain in gold/black color and an ultra-light aluminum rear sprocket with a mud-resistant profile, along with a 13-tooth front sprocket — a standard setup ready to be installed on your motocross bike.

Designed for muddy terrains and off-road demands, this kit facilitates mud evacuation thanks to the specific geometry of the rear sprocket. The gold/black finish of the chain adds a racing touch to the swingarm and allows for easy visual wear monitoring. The 13/50 sprocket setup offers a commonly used compromise in motocross for versatile usage.
Compatible with many motocross machines — among the main models: KTM 250 SXS (2004) and KTM 250 SX (2004). Always check the compatibility of dimensions before installation. For proper installation, tighten and check the chain tension according to the manufacturer's recommendations.
