Product details :

Features

EK/PBR 520MRD7 13/49 Chain Kit - ultra-light sprocket: a chain kit designed for motocross bikes where every gram and every link matters. This 520 setup in gold finish combines a high-strength chain with an ultra-light aluminum sprocket to reduce unsprung mass and keep the transmission responsive without compromising wear resistance.

Sprocket/Rear Sprocket Compatibility: 13/49 (delivered ready for installation)
Pitch: 520
Number of Links: 114
Color: Gold / Gold (chain and sprocket)
Sprocket Material: Aluminum – ultra-light
Weight: 1.47 kg for 100 links (manufacturer reference)
Relative Lifespan: 450 (manufacturer value for 100 links)

Designed for motocross and competition use, this EK kit is aimed at riders looking for a lightweight and durable setup for their trajectories and accelerations. Ideal for models such as HONDA CRF 450 RWE (2026), CRF 450 R (2026), and CRF 450 R (PE07) (2020) — check the exact fit for your machine before installation. Installation and tension should be checked regularly: a well-adjusted transmission prolongs lifespan and maintains the efficiency of the final drive.
