You should use the exact plug that is specified by the manufacturer. But , yes , they probably are pretty much the same because the vast majority of Chinese bikes of every shape and size use an engine ripped off from the humble Honda CG125. Yea unfortunately I don't have a manual with it to get the specs from. I thought I'd be able to find one online easy enough but apparently it's like gold dust lol what spark plug does the Honda use? Good morning, ok , its not based on a Honda CG125 , it looks more YBR 125 to me . Anyway , its an NGK CR7E plug but apparently there is a better alternative.
