Starorb, I am sure it is a misunderstanding, as this forum has had a few spammers recently, and it also got hacked twice, so everyone is somewhat jittery regarding this subject.
It is not considered good forum etiquette to write multiple new posts on the same subject (spark plug) .
The brisk Plug has worked well for other bike owners.
I had fitted a brisk Plug on my 500 xciting previously , and found it gave improved performance.
However, for my situation, there was cold spluttering, so I replaced with ngk iridium Plug, still have better performance with no cold spluttering.
