Champion made Harley plugs for years, you could tell by the markings on the metal part of the plug.
The removable caps, make darn sure you tighten them securely with a pair of pliers when installing. New to riding Harleys, I had a screw post cap come loose on my Fatoby and a plug wire fall off. I thought I'd just reach down and put it back on rather than try to pull over in traffic. Bad call. Shocking, really. 😁
I customise my '87 EVO, to an old school style, and want the spark plug terminals as in the picture.
After doing some research, the situation is as below:
Champion RN12YC ............ non removable top nut
Autolite 4265 ....................... non removable top nut
NGK BPR5ES ..................... removable top nut
Autolite 64 ........................... removable top nut

I have just bought the NGK BPR5ES ones.

That terminal looks like vibration from the engine will cause it to fail and break off at the 90 degree bend. You had better carry a couple of extras.
Looks like something that belongs with a Delorto or Velocity stack for a weekend bike show only kinda chopper. Not recommended for performance or trips over 25 miles in my opinion….
