GRRRR, pick your words correctly folks....
There are 2 manuals. The OWNER'S MANUAL, and the SERVICE MANUAL.
The OWNER'S MANUAL is a booklet that fits under your bike's seat and is the thing Felix is referring to where you record services done if you do that.... This comes with the bike when new.
The SERVICE MANUAL, aka Factory service manual is a massive book you can knock somebody unconscious with, which includes procedures to disassemble and reassemble the entire bike, back to front.... These do not come with the motos, used or new. They are also about $80.
