EK/PBR 520SRX2 Chain Kit 13/42 - standard sprocket, signed EK CHAIN. Designed for roadsters and urban mounts, this kit combines the SRX2 chain with a 13-tooth sprocket and a standard 42-tooth sprocket for a defined gear ratio. The SRX series is known for its good performance/value compromise, with regular improvements making it a common choice among riders looking for reliable equipment.
Kit suitable for common maintenance interventions: complete replacement of the primary transmission to restore consistent engine braking behavior and throttle response. The 108-link chain allows for adjustment based on the model (riveting or cutting may be necessary depending on the motorcycle). Compatibility examples: Cagiva Supercity 125 (2002–2004).
Installation recommended by a professional or an experienced DIYer in tension adjustment and riveting to ensure safe operation and optimal longevity.
