The factory service manual for the 2026 KODIAK 450 EPS carries Yamaha part number LIT-11616-39-30 and addresses model code YFM45KPHTF. Yamaha wrote a single book for the 2026 KODIAK 450 range, so the base KODIAK 450 and the EPS SE XT-R appear in the same pages.
Electric power steering work is handled in the chassis and electrical sections with its own diagnostics, which matters if you are chasing an assist fault rather than a mechanical steering problem.
Elsewhere the book runs the usual factory ground: scheduled maintenance, engine removal and rebuild, transmission and final drive, fuel system, cooling, brakes, suspension geometry, and wiring diagrams with connector locations. Every specification is given as a nominal value with a service limit, so you can decide whether a part is still usable.
Match YFM45KPHTF to your machine first; the 450 codes differ only in the middle letters.
