• Number of links: 112
• Weight: 1.76 kg / 100 links
• Colour: Steel / Steel
• Relative lifespan: 2400 (for 100 links)

Ideal for a wide range of motorcycles — from trail to sport, including enduro, supermoto, roadster, and vintage — this chain can handle the high demands of engine torque and offers standard installation on compatible 520 sprockets and crowns. It maintains the quality and precision craftsmanship characteristic of EK products while remaining a cost-effective option for transmission maintenance.

Particularly suitable for machines such as GAS GAS SM 700, KTM 690 SMC R, or YAMAHA YZ 450 F (check the number of links and tension adjustment before installation).
