During some time I was trying to buy one for my CB750, just for originality purposes. I recall it was listed at something as 90 bucks. I was chatting about it with my local Honda guy and he told me: "are you crazy? For a fraction of that you can buy the individual wrenches, far better quality" I thought about it and that's what I did. So when I ride my bike I know the toolkit is not original, but I also know if I get a breakdown I'm better off.
