JT/PBR 520HDS 13/50 Standard Chain Kit - Ultra-Light Sprocket by JT DRIVE CHAIN: a kit designed for motocross sessions where durability and lightness are sought. 520 pitch chain in black/steel finish with XS-Ring seals and HDS (super-reinforced) design to withstand the demands of the terrain. The rear sprocket is made of ultra-light aluminum, reducing unsprung mass without compromising the original geometry.
Suitable for motocross machines such as the KTM 125 SX (2017, 2018, 2019) and other models that accept the 520 pitch and 13/50 ratio. Ideal for riders who want a drivetrain ready to tackle the tracks, with a black/steel look that complements modern machines. Be sure to check the exact compatibility with your model and, during installation, adhere to the recommended torque and tension to ensure safe operation.
