EK/PBR 520SRX2 Chain Kit 14/52 - ultra-light sprocket: a transmission kit designed for motocross where weight and reliability go hand in hand. This kit combines a 520 chain with a golden visual finish and an ultra-light aluminum sprocket to reduce weight without complicating post-track interventions. Designed for riders looking for a simple installation and a sleek look on their enduro or motocross bike.
The 520SRX2 from EK CHAIN is aimed at motocross riders who want a transmission ready to replace the original: installation, tensioning, and adjustment remain standard for easy maintenance. The aluminum sprocket reduces rotational inertia, while the golden finish adds an aesthetic touch to a prepared machine.
Practical advice: check the number of links needed for your model and adjust the length before installation. Common application examples: KTM 300 EXC (1998 - 300 cm3) and other enduros equipped with 520.
