kawasaki ER5 owners book
 

I am looking for a owners book that comes with the bike normally

Dont have one, however if you get a factory service manual, you will probably shell out about the same amount of cash and get far more info (enough to rebuild from the ground up) and they usually have a maintenance schedule in the front to help out.

Check the Manuals sticky to see if one is available online or pay for the paper copy (much nicer and worth every penny)
