This EK/PBR 520M3 14/50 chain kit has been designed for motocross riders seeking a lightweight and durable drive system. The 520M3 chain, combined with an ultra-light aluminum sprocket, reduces unsprung mass to enhance the bike's handling and responsiveness on technical sections and jumps. Gold/gold finish for a racing look and corrosion protection.
Easy to install, this kit offers an interesting compromise between lightness and resistance to abrasion and traction, without unverified technical claims. Ideal for equipping motocross machines that accept a 520 pitch, such as the KTM 144 SX (2008). Be sure to check the tension and alignment after installation and lubricate the chain regularly to maximize its longevity.
