2006 S2R 800
Changing my plugs today and found a Champion RA59GC in the lower cylinder and a RA4HC in the upper.
As far as I can tell the only plugs for the bike are the Champion RA4HC or the NGK DCPR8E. Did a search at the Champions site and could only find an application for the RA59GC being for a Lamborghini Diablo. While it still Italian its not really a Ducati.
Any one else find this plug on their bike?
Note, the plugs have been changed once by the dealer.

Thats the first time I've heard of that plug.
Denso IXU24 shows up as another possible option
RA59GC is a desmoquattro 4v plug, std in everything from 851 probably. certainly 916 onwards, excepting the ones that had the surface dischrage ones - 916sp mostly. it would cross reference to an ngk 9 series, probably an evx or eix number.
RA4HC crosses to a ngk 8, some 2v models ran the RA6HC, which crosses to an ngk 9
I would ask your dealer this question. Either it was a mistake or the dealer had a reason. If it was a mistake, the dealer needs to know. If there was a reason, you need to know why. I prefer the NGKs over the Champions.
Someone could have broke the original, and put that back in as a replacement.

I haven't looked up your particular plug heat range, but it's common the run a slightly cooler plug in the rear because of the lack of air flow. Not too common on the street, but VERY common at the track.
