What about your wheels? I’m the type who wants to keep them clean on a budget! The king of OEM parts: “Honda OEM swap” flanged lock nuts M12-M18, please refer to this.

Basically, I’m not a fan of the lock nut and washer configuration.
Depending on the location, that configuration is necessary, but there are also places where it isn’t.

By switching to flanged lock nuts,
you can reduce the number of parts by one, which also improves work efficiency.
Also,
I think large nuts like these have a pretty high probability of being reused.
The reasons are that the parts cost quite a bit, and they don’t wear out easily.
When you’re told a single nut costs 800 yen or 1500 yen, it’s a bit much.

But Honda, the king of OEM parts.
It’s a wonderful manufacturer that achieves both superior quality and low prices.
I was thinking about researching flanged lock nuts
and did a rough search, so please use it as a reference.

Honda 90306-KF0-003 M12-P1.25

It can also be adapted to the front of Suzuki GSX1100S and other models.

Honda 90305-GE8-003 M14-P1.5

It’s also perfect for the front of the GPZ550 (*´ω｀*)

Honda 90305-ME5-003 M16-P1.5

It’s also perfect for the rear axle nut of the GPZ550 (*´ω｀*)

Honda 90305-MB4-003 M18-P1.5

Perfect for models with a 20φ axle shaft diameter and a single-step thinner threaded section.
The Z1000MK2 and others work with this too.

Honda 90305-MCC-000 M18-P1.5 (2mm thinner)

I just realized something.
If you measure the height of a flanged lock nut, you can somehow figure out the diameter? *Excluding the thin ones.
