Standard ngk. I made a thread about this a month or two ago. Here and on ktm talk. Long story short; iridium aren’t needed and provide no benefit. Stick to the plain ol br7es

The ES plug is least resistant to fouling and wears out the quickest.  The EG plug is a reasonable half step between the ES and iridium.  The iridium will likely never wear out and is very resistant to fouling.
