LIT-11626-14-36 is the 2001 YZ125 service manual, and the machine it documents is model code YZ125N1.
A season-specific book matters more on this bike than on most. Yamaha revised the YZ125 every year, sometimes substantially, and a torque figure or a clearance taken from an adjacent year's manual can be wrong in a way that costs an engine. The frame label settles it: YZ125N1 means this volume.
What the manual sets out
- Engine and chassis work in the factory's sequence, with the illustrations that go with it
- Service limits for the parts you are expected to measure during a rebuild
- Torque specifications, ignition timing, carburettor settings and suspension figures
- Wiring diagram for the harness as built
It is the reference Yamaha's own dealer technicians used while the bike was current.
