About the Yamaha XT125
Early XT125 service parts and later XT125R/X carburetor kits.
The early Yamaha XT125 is a four-stroke trail motorcycle. Later XT125R and XT125X models share the XT125 name, but the repair parts featured here are divided by full model code and year.
Early XT125 versus XT125R and XT125X
For an early XT125, the selected float needle and seat lists 1982–1984, while the fork seals and rear brake shoes list 1982–1983. For an XT125R or XT125X, the linked carburetor kit lists 2005–2008. This split is particularly useful when a search returns early and later fuel-system parts together.

Before orderingModel, frame and component identification

- Record carburetor markings before deciding between an early float-valve repair and a later R/X kit.
- For brake work, identify the actual brake assembly and its front or rear position before selecting friction parts.
