EK/PBR 520 SRX2 Chain Kit - 16/45-122: a chain and sprocket set designed for roadsters looking for a good balance between durability and cost. The SRX2 kit from EK CHAIN combines a reinforced 520 chain and a standard steel sprocket to ensure reliable road transmission.
This kit is aimed at riders who wish to replace their transmission with a simple and robust setup: the reinforced 520 chain provides better resistance to the torque stresses typical of roadsters, while the steel sprocket ensures controlled wear in road use. Riveting is required during installation; visiting a workshop is recommended if you do not have the appropriate tools.
Compatibility (model examples): CF MOTO 800 NK SPORT (2025), CF MOTO 800 NK ADVANCED (2025), CF MOTO 800 MT SPORT+ (2025). Be sure to check the number of links and the pitch before installation, and perform regular lubrication and tensioning to optimise the longevity of the transmission.
