Model code YXZ10YMSKL is the 2019 YXZ1000R EPS SE, and the factory manual for it is LIT-11616-32-27. Yamaha used that one volume for the 2019 YXZ range, so the EPS, EPS SS and EPS SS SE are documented in it as well.
Working on a machine with a shared manual is straightforward once the code is confirmed. Common procedures apply across the range; the tables identify the exceptions by code and leave the decision to you rather than averaging the figures.
Coverage includes scheduled maintenance, engine disassembly and measurement, transmission and final drive, chassis, suspension and steering, brakes, fuel system, and electrical fault-finding. Torque values and wear limits are stated throughout, and the wiring diagrams are complete, which is the part most owners end up needing sooner or later.
