A Sears Craftsman 12 point will work. But as 98ACE750 said the Honda socket actually does the best job. It looks cheap but works well. Most of the time, the whole set is very close to the cost of the plug wrench, but in your case, it sells for around $60. Looks like you have a couple of special tools in there. Might be worth considering since they might be needed to work on the bike.
