Fitment
- Sinnis ST125 154FMI YBR-pattern applications

Compatibility Check
This is the four-friction-plate YBR-style clutch drum assembly. Before ordering, compare the original unit with the photographs and check the engine code, clutch plate count, centre spline, pressure-plate shape and four-spring layout.
Do not order only by engine capacity. Some visually similar 125cc and 150cc engines use different clutch drums, different spline arrangements or five-plate clutch assemblies.
Installation
Installation requires removal of the engine side cover and correct reassembly of the clutch operating mechanism. Prepare the friction plates as required by the motorcycle manufacturer's procedure and tighten all fasteners to the correct workshop specifications. Professional fitting is recommended where the correct clutch procedure or torque settings are not known.
