That is truely an amazing score. The 72" long harbor freight is $1000 and the 60" is $700-750 on sale. They are pretty good tool chests, but not as many drawers as that. The Snap-On chest is $3000 for one that size but only 12 drawers if I recall correctly.
That probably is $15-18k of tools when bought separately today . Those are some Cool Tools.
Factory service manuals will tell you which you need for the bikes you have or may want. You could sell off individually the others, but it is worth far more kept together.
Great collection of tools if you wanted to offer Honda work as a side job or retirement job.
