For 2019 the R1M is coded YZFR1MKC, and Yamaha's service manual for it is LIT-11616-32-57. The standard YZF-R1 of that year is covered in the same book, with variant-specific content marked where the two machines differ.
A note on the part number: it is not the one used for 2018, even though the bikes are closely related. Ordering by year alone is how people end up with the wrong reference, so match LIT-11616-32-57 and YZFR1MKC together.
The material itself is the full factory set. Maintenance charts, engine work laid out in disassembly order with inspection steps between, cooling, lubrication and fuel system procedures, chassis and suspension specifications, brake service, and an electrical section built around diagnosis rather than description. Torque values and wear limits accompany each assembly, which is what you need when a job has to be right the first time.
