2026 Yamaha WR125R Service and Repair Manual

Fresh model, fresh publication: LIT-11616-39-57 is Yamaha's service manual for the 2026 WR125R, and the machine is identified by code WR125RTL. Coverage is the 2026 model year on its own.

For a current bike the value of the factory text is mostly in the numbers. Tightening torques, assembly clearances, adjustment settings and the specified service intervals are stated exactly as the factory intends them, which matters when you are working on components still under warranty conditions. Wiring diagrams and diagnostic procedures round it out.

Confirm WR125RTL on the frame plate before ordering, since a neighbouring year carries a different suffix and a different publication number.

The sections follow a predictable order, general information first, then maintenance, engine, chassis, fuel system and electrics, so a figure can be located quickly while the bike is apart. Nothing is written as encouragement; it is all instruction and measurement, which is what makes it useful on a cold morning halfway through a job.
