I use it on my CB750F.
I have a theory that this kind of plug is better than Iridium plugs for Carburetor Vehicles with Large type air-cooled engine.
The reason for this is that I do not feel any dissatisfaction with this Plug in terms of performance.
It is no problem even if it revs high continuously.
In the case of air-cooled EngineCarburetor Vehicles, there are times when the plug needs to be replaced depending on the condition of the fuel system, but at such times, the cost effectiveness of being able to replace the plug with a new one without hesitation is the biggest advantage, isn't it?
As a side note, another little-known advantage is that it is easy to check the degree of burning. (Because I'm presbyopic?)
After that, it's a sense of trust backed up by our long track record.
Looks like you access from European region.
