EK/PBR 520MRD7 Chain Kit 14/52 - Ultra-Light Sprocket
Designed for off-road and competition, this EK chain kit combines a high-performance 520 chain with an ultra-lightweight aluminum rear sprocket. The construction aims to reduce friction while providing good resistance to traction and abrasion on the demanding terrains of motocross. Gold finish for an aesthetic appeal on your drivetrain.
Ideal for riders looking to lighten the entire transmission without sacrificing race performance, this kit pairs well with modern motocross bikes such as the KTM 350 SX-F (2026), GAS GAS MC 250 F Factory Edition (2026), or the HUSQVARNA FC 350 (2025). Ensure proper adjustment and tension after installation, as well as regular maintenance (cleaning and lubrication) to preserve the longevity of the chain and sprocket.
