LIT-11626-36-40 is the part number to look for if you are servicing a 2023 YZ125X. The machine carries model code YZ125XP, and Yamaha wrote this manual for that season alone.
Cross-country bikes get a harder life than track bikes in some respects, with more hours, more water and more debris. The factory manual meets that with intervals for each maintenance item, measurement points with limits for the parts that wear, and full procedures for the jobs that come round: top end, clutch, gearbox, suspension, wheel and brake work.
Ignition and fuel system settings, torque tables and the wiring diagram complete the coverage. Keep in mind that the YZ125X and the motocross YZ125 have separate manuals in this era, so confirm YZ125XP on your frame label rather than ordering on the model name.
