EK CHAIN 520 SRX2 Chain Kit – 14/52-118 (standard steel sprocket)
The EK SRX2 chain kit offers a sought-after compromise for motocross riders: durability and controlled cost. Complete and ready to install, it combines a reinforced pitch 520 chain with a 14 tooth sprocket and a rear 52 tooth standard steel sprocket, for a total of 118 links. The attachment type is rivet type, suitable for demanding off-road use.
Designed for motocross use, this kit is suitable for riders looking for a reliable chain for muddy and dry terrain. It is frequently fitted on modern enduros and motocross bikes — for example, it corresponds to the specifications of the KTM 350 EXC-F SIX DAYS (2026), GAS GAS EC 450 F (2025), and KTM 350 EXC-F (2026); however, please check the exact compatibility with your machine before installation. Riveting should be done carefully by a professional or an experienced mechanic to ensure a secure connection.
