Product details :

Features

EK/PBR 520M3 13/49 Chain Kit - Ultra-Light Sprocket by EK CHAIN: a kit designed for motocross riders seeking lightweight and durability for the final drive. Built for the terrain, it combines a robust 520 chain with a 13-tooth sprocket and an ultra-light 49-tooth aluminum sprocket, reducing unsprung weight without sacrificing wear resistance.

Color: Gold/Gold — sleek look and easy visual identification.
Number of links: 114 — cut and adjust according to installation.
Pitch: 520 — standard format for motocross and off-road.
Weight: 1.36 kg / 100 links — low mass index for better cornering feel.
Relative lifespan: 450 (for 100 links) — comparative longevity indicator.
Sprocket material: Aluminum — weight savings and reduced inertia.

This kit is aimed at motocross and competition practitioners who want a final drive ready to tackle the track: starts, jumps, and hard accelerations. Easy to install and maintain, it is suitable for riders equipping YAMAHA YZ 450 F (2023 and 2021 CJ23) and YZ 450 FX (2020). Manufacturer reference: not provided.
