EK/PBR 520MRD7 Chain Kit 13/49 - Ultra-light Sprocket
Designed for motocross and the demands of rough terrains, this EK CHAIN kit combines a high-performance 520MRD7 chain with an ultra-light aluminum sprocket. The set aims for easy installation and responsiveness of the drivetrain: 13-tooth front sprocket and 49-tooth rear sprocket for a ratio suited for motocross bikes.

- Front Sprocket: 13 teeth
- Pitch: 520
- Relative lifespan: 450 (reference 100 links)

The aluminum/gold color combination gives a racing look while reducing unsprung mass. Ideal for riders looking to optimize grip and drivetrain response without compromising abrasion resistance. Regular maintenance and proper tension are recommended to maximize longevity in off-road conditions.
Compatible with many motocross models — including the SUZUKI RM-Z 250 (2010-2012) — this kit is a versatile solution to refresh the drivetrain before the competition season.
