If this is the only thing you have to learn about how to work on your bike then it is worth the money and will help you in being able to do the work on the cycles listed in the manual. The biggest thing that comes out is the quality of the pictures is lacking in detail. The information is good if you have fairly good knowledge of motorcycles or have a mechanical apitude when it comes to repairing or figureing out how things work or go together. Could be better but it will help work on the cycles listed on the manual.
