Nine model years, one book. Yamaha's LIT-11616-XT-25 documents the SEROW from 1992 to 2000, and the first-year machine in that span carries the code XT225D.
Match the code before you match the year. A bike this long in production accumulates swapped parts, and the tables in the manual are indexed by code, so XT225D tells you which figures are yours.
The content is the factory's service text rather than a summary of it: torque specifications, wear limits and running clearances, step-by-step engine and chassis work in the intended order, wiring diagrams, and troubleshooting arranged so that a reported symptom leads to a test rather than a guess.
Quote LIT-11616-XT-25 if you need to check against paperwork already on the shelf.
