2018 Yamaha YZF-R1S Service and Repair Manual

The R1S has its own manual. Yamaha assigned LIT-11616-30-62 to it, separate from the books covering the standard R1 and the R1M, and the 2018 machine is coded YZFR1SJCGY.

That matters when ordering. An R1S owner handed the standard R1 manual will find specifications that do not line up, so the part number above and that model code should be confirmed together before anything else.

Coverage is limited to the 2018 model year, which keeps the content unambiguous. Inside are the periodic maintenance tables, engine removal, disassembly, inspection and reassembly, cooling and lubrication, fuel system work, chassis and suspension specifications, brake procedures, and electrical diagnosis with wiring diagrams. Torque figures and service limits are the factory's throughout — the numbers to work to whether you are setting valve clearance or reassembling a front end.
