EK/PBR 520SRX2 Chain Kit 13/52-116 - Standard Sprocket
Designed for off-road riders seeking a reliable, uncomplicated transmission, this EK SRX2 chain kit brings together the essential components to get a motocross bike back in working order. The 520 pitch and 116 links cover a wide majority of setups, while the SRX2 design incorporates QX-Ring seals for better lubricant retention.
The aluminium sprocket keeps the assembly compact and lightweight, while the chain equipped with QX-Ring limits lubricant loss for more manageable maintenance intervals. Easy to install for both amateur and professional mechanics, this kit is particularly suited for motocross machines where flexibility in transmission and reliability in tough conditions are sought after.
Example of application: GAS GAS EC 350 F (2024 - 350 cc). Before installation, check the exact compatibility of the sprocket/sprocket ratio with your model and adhere to the manufacturer's recommendations for tension and lubrication.
