A 2025 TT-R50E carries the model code TTR50ES, and the service reference Yamaha wrote for it is LIT-11616-31-42. One book handles a long stretch of production: the 2018 through 2026 model years, with the TTR50E covered alongside.
That breadth is useful if the bike has passed through a family. A machine bought used and undated can still be serviced correctly because the year-by-year differences are set out in the same reference rather than scattered across several.
Expect factory procedures throughout. Clutch and transmission work, top-end service, carburettor settings, brake and suspension adjustment, and the electrical system with Yamaha's wiring diagrams. Torque values are given where the fastener is discussed.
Confirm both identifiers, LIT-11616-31-42 and TTR50ES, and there is no ambiguity about what you are working from.
