Discontinued replacement found! Koshihara Lock Nut Wrench for VFR400R/RVF400 Pivot Adjust Wrench 07908-4690001 (discontinued)

I was asked to replace the pro arm bearing on a VFR400R (NC30), but…
wait, I don’t have this tool on hand… Well, that makes sense—it’s a 400 after all. There’s no way I’d have it.

So I checked the manual and found it was Honda OEM 07908-4690001 (discontinued). (´;∀;)
Should I just turn down the job? Well, I decided to search for an alternative tool.

The lineup of OEM tool reproductions from this company called Koshihara is amazing! KOSHIHARA N717

I could have made it in the old days, but… these days, buying is the best option.

I have a lathe and milling machine, so manufacturing is possible.
However, when you factor in material costs and time, buying is the best option.

The reason is “there are affordable, quick, and quality reproduction tools”
which I’ve been curious about for a while now— “Koshihara.” This was the perfect timing to try them out.

The drive is 1/2 inch.

It costs 3,449 yen plus shipping, but it’s super reasonable.
The black finish gives it quite an authentic OEM look.

The “smooth” fit is just wonderful (*´ω`*)

Removing the swingarm has become somewhat traumatic for me.
I want to walk through life carefully and safely, you know?

There’s minimal play, and my expectations are sky-high (*´ω`*)

It came off easily (*´ω`*)

The wide claw width helps too.
It came off smoothly without any sudden jerking (*´ω`*) Success!

Koshihara OEM reproduction tools have high expectations

You can’t remove it without this type of tool.
Most OEM tools are discontinued, so this is really helpful.

I’m interested in various other tools, so I’ll check them out when the timing is right.
If you’re planning to remove the swingarm on a VFR400R (NC30) or RVF400 (NC35), check this out for reference.
