EK/PBR 520MRD7 Chain Kit 13/49 - Ultra-Light Sprocket

Designed for off-road and competition, this EK/PBR 520MRD7 chain kit combines a high-performance gold chain with an ultra-light aluminum sprocket. Intended for motocross riders, it aims to provide responsive transmission while minimizing unsprung mass for better handling on jumps and acceleration.

• Color: Gold / Gold
• Pitch: 520
• Number of Links: 114 (to be shortened according to installation)
• Sprocket: Ultra-light aluminum, designed to reduce weight without compromising track performance
• Relative Lifespan (100 links): 450
• Weight: 1.47 kg / 100 links

The chain is treated to resist abrasion and the tensile forces encountered in motocross. The gold finish provides corrosion protection while giving a sleek racing look. Supplied in a 13/49 configuration, this kit is suitable for modern 450 motocross bikes — including FANTIC XXF 450 (2026) and YAMAHA YZ 450 F (2021–2022) — and is aimed at riders demanding longevity and lightweight performance.

Note: The final adjustment of length and installation should be performed with appropriate equipment and, if necessary, by a professional to ensure the safety of the transmission.
