Fitment
- Yamaha YBR125 using the 4-friction-plate 5VL/YBR-style clutch
- 154FMI YBR-pattern 125cc engines using the same 4-plate clutch assembly
- Selected Jianshe / Chinese YBR-pattern 125cc and 150cc applications using the same clutch
- 156FMI-5 applications only where the original clutch matches this 4-plate YBR-pattern unit
Compatibility Check
Engine codes alone are not always sufficient to identify the clutch. Before ordering, compare the photographs with the original assembly and check the inner drum shape, centre spline, four-spring layout and number of friction plates. Some engines carrying similar 156FMI markings use a different CG-pattern clutch and are not interchangeable.
Installation
Installation requires removal of the clutch-side engine cover and correct reassembly of the clutch operating mechanism. Prepare replacement friction plates as required by the service procedure and tighten all fasteners to the motorcycle manufacturer’s specifications. Professional installation is recommended if the correct workshop procedure and torque settings are not available.
