That is mostly likely an illegal photocopy or print-from-scan copy. He seems to be doing a lot of it. He will get in serious trouble if he were reported to Kawasaki and the other manufacturers....
Actually, Kawasaki (and Honda and Suzuki and Yamaha) don't really care- at least not enough to police ebay once in a while. I was burned by this in the past, as an ebay seller purposely misrepresented the product. The seller had manuals from all four big Japanese manufacturers. I contacted their legal departments, and only Kawasaki and Honda said they were concerned about the issue. About a week later, all of the seller's products had been pulled from ebay, only to return again a month later under a different name.
I would rather pay a little more and get a genuine manual rather than support the people who profit from photocopying. I am doubtful that many people would consider buying a photocopied novel or other printed work, but for some reason they find it OK for a service manual.
All that aside, the quality of those fake manuals is generally lousy- cheap paper and binding, etc. Real manuals stand up to years of greasy hands
