The EK/PBR 520MRD7 13/48 Chain Kit by EK CHAIN is designed for motocross riders seeking a lightweight and robust setup for cross outings and competition. Comprising a chain with a pitch of 520 and an ultra-light aluminum sprocket, this kit prioritizes weight reduction without sacrificing durability against abrasion and traction encountered in off-road conditions.
- Color: Gold / Gold — sleek look and easy visual identification.
- Number of links: 116 — full length ready to be adjusted according to the setup.
- Life span index (ref.): 450 (for 100 links).
- Weight: 1.47 kg for 100 links — optimized mass for responsiveness.
- Sprocket/gear configuration: 13/48 — traction-oriented ratio.
Designed to minimize friction while providing good wear resistance, this chain/sprocket combination is suitable for the specific demands of motocross: repeated jumps, dirt projections, and constant stress.
