This 202 page pdf document, Kawasaki KS125 KE125 1974 – 1985 Motorcycle Service Repair Manual provides detailed service information, step-by-step repair instruction and maintenance specifications for the 1974 – 1985 Kawasaki KS125 and KE125 motorcycles – both US and European motorcycles.

This Kawasaki KS125 KE125 1974-1985 Motorcycle Service Repair Manual is designed primarily for use by motorcycle mechanics in a properly equipped shop. However, it contains enough detail and basic information to make it useful to the motorcycle user who desires to carry out his own basic maintenance and repair work. Since a certain basic knowledge of mechanics, the proper use of tools, and workshop procedures must be understood in order to carry out maintenance and repair satisfactorily; the adjustments, maintenance, and repair should be carried out only by qualified mechanics whenever the owner has insufficient experience or has doubts as to his ability to do the work so that the motorcycle can be operated safely.

In order to perform the work efficiently and to avoid costly mistakes, the mechanic should read the text, thoroughly familiarizing himself with the procedures before starting work, and then do the work carefully in a clean area. Whenever special tools or equipment is specified, makeshift tools or equipment should not be used. Precision measurements can only be made if the proper instruments are used, and the use of substitute tools may adversely affect safe operation of the motorcycle.
