As part of my PDI, I wanted to make sure it wasnt a cheap spark plug from China... It is the honda clone. - this is the one I bought :

They have it marked wrong on the site, its not the 54B. Turns out to be a jonway yy250 MC 54 ( or hell maybe there are all the same! ) , it runs very well, hit 72 mph on it today, still a little throttle left also got it all registered today! no more riding Dirty
From my online search, Roketa is just a branding company, not a Manufacturer, while Jonway is the real Manufacture.
