EK CHAIN 520MRD7 14/50 Chain Kit - ultra-light sprocket: a kit designed for cross discipline, combining lightness and robustness to tackle demanding terrains. The 520MRD7 chain features a Gold/Gold finish and consists of 114 links (pitch 520), with a weight of 1.47 kg for 100 links, ensuring a weight/strength compromise suitable for jumps and accelerations typical of off-road riding.
- Sprocket Material: Ultra-light aluminum, reduces inertia without sacrificing performance in off-road use.
- Sprocket/Rear Sprocket: 14/50, a common configuration for cross practice.
- Relative Lifespan: index 450 (for 100 links), an indicator of longevity under normal usage and maintenance conditions.
- Compatibility: suitable for cross models (e.g. YAMAHA WR 426 F 2001-2002).
Designed to withstand the traction and abrasion encountered in competition or enduro outings, this EK CHAIN transmission is easy to install and maintains like a standard chain (tension control, regular lubrication). Ideal for riders looking for a lightweight transmission without extreme modifications to the mechanical behavior of the machine.
