LIT-11616-38-66 is the factory service manual for the YZF-R9, written to span the 2025 and 2026 model years and to include the 70th Anniversary Edition. The 2025 standard machine is coded YZFR9SB.
On a recently introduced model the factory book is often the only thorough reference there is, so the identifiers matter more than usual: part number LIT-11616-38-66, model code YZFR9SB.
Content is arranged for shop use. Maintenance intervals and general information first, then engine removal and rebuild with inspection steps in sequence, fuel system, cooling and lubrication, chassis and suspension specifications, brake procedures, and an electrical section covering diagnosis, fault codes and wiring. Torque values and service limits are quoted as Yamaha specified them, which is the whole reason to work from this rather than anything else.
