Important Fitment Notes
- These YB125 parts catalogues list 5VL-E8101-20 directly as the shift-shaft assembly.
- Market/model codes matter; compare the OEM reference if the motorcycle is a different YB125 variant.
Do not order by engine capacity or model name alone. Compare the splined pedal end, shaft length, selector-arm shape, spring location and Yamaha OEM reference with the original component before fitting.
Installation
Replacing the selector shaft may require removal of engine-side covers and correct positioning of the selector mechanism and return spring. Inspect the shaft oil seal and related circlips/springs during installation. Confirm smooth selection of every gear before road use. Professional installation is recommended if you are not experienced with motorcycle gearbox mechanisms.
