Model code XV17ATSAR identifies the 2011 Silverado S, and LIT-11616-21-68 is the Yamaha part number of the service manual that covers it. Those two numbers are worth writing on the inside cover of whatever you keep in the garage, because they are what confirms a procedure belongs to your bike.
One book, seven model years
Yamaha wrote this volume to span 2008 through 2014 and to take in the Road Star, Road Star S and Road Star Silverado. Shared coverage of that kind means the tables often show you what carried over and what did not, which saves a lot of cross-referencing when a supplier lists a part by a neighbouring year.
The content is the factory content: disassembly and reassembly sequences, torque figures, clearances and wear limits, periodic maintenance intervals, electrical schematics and symptom-based diagnosis. Nothing has been paraphrased into owner-friendly language, which is the point.
