I used in a 2002 Honda XR250R. I have noticed much easier hot or cold starts. Engine seems to respond a little quicker on the tight single tracks I ride. I used to use 2 standard plugs a season, now just 1.

Bike definitely has some more pep, bring on the increased fuel mileage. If I stay outta da throttle.

These Spark Plugs Work Great
I have a 1996 Honda CBR600 F3. Installation was a little hard because its a sport bike after all but with the new plugs it runs like its brand new.
