What goes in a basic motorcycle repair tool box?

My boyfriend is going to be taking motorcycle repair cles soon, and his birthday is also coming up, so I thought it would be a nice gift to get him various tools to use for his cl and for working on motorcycles in general. What are the basic tools that he should have? He already has some basic tools like wrenches, screwdrivers, and hammers. Or does anyone know of a basic all-in-one kit tailored for motorcycle repair that I could buy?
