Toolkit, what is part 89211-KJ2-000

I am assembling a mobile tool kit for a 5th gen. I would like to know the purpose of the attached. Here is the descriptions:

89211-KJ2-000
WRENCH, BOX (8MM)



I read on one blog that this part is for the preload on Gen 2-4 bikes, but cannot identify why it is in the 5th gen kit. Also, the Honda description calls this a box wrench. Is that description wrong or are all of the pictures showing a socket wrong?

If this is indeed a socket, what is it used for? Would a typical nut driver be long enough for the same task?


Also, is it necessary to carry a spark plug socket? If I am meticulous with maintenance, can I expect to have a problem with a plug that must be fixed on the road? I have iridium plugs.

 

I don't remember seeing that in the tool kit for my '99, but then I've not looked in it for 10 years or more. Personally if I were assembling a tool kit for traveling in the US or western Europe, it would consist of a few common sized combination wrenches, a small crescent wrench, a couple screwdrivers, the chain adjustment tool, a credit card, and a cell phone.

A tire repair kit would be a thought, but I've had one flat in 50 years of motorcycle touring so I'd risk the odds.

 

Got that all thanks.

I thought of a crescent wrench but will I need one if I have the wrenches listed in the kit - 8, 10,12, 14, 17, 22mm? I only ask this because it is always best to use a fixed wrench over the adjustable if available. Maybe the crescent is one of those tools that if I come across another broke down biker, I can help them out, no matter what bike they have.

I was also debating a flat kit thanks.

What do you think of a compressor? I always carry a Chinese $20 compressor in my car. I have had several leaks over the years, and that helped me get to the tire repair place without changing to the spare tire. I agree the chances of a flat or destroyed tire are slim, but the chances of having a leak are significant.

 

The main reason for a crescent wrench is for the odd time that you need to remove a bolt that has a nut on the back side.

Pashnit.com has a pretty nice tire repair kit but it's awfully pricey, I figured if I ever started to carry one I would probably spend the money on the one from Aerostitch. My experience with leaks is about the same as with flats: very rare. I've picked up a nail or two over the years, just never while I was on a trip, maybe three times total that I can remember.

 

Ah gotcha. It would be nice to double up on the combination wrenches for this purpose, but the crescent wrench solves this with many fewer wrenches. I will add this to my list thanks.
