If you mean the nose section, I have a spare plain red RR4/5 one. Not sure sure if it's the same as the RR6/7 though. Edit: Here are some of the bits I'm hoarding.
So, Mr Muffy. Would you also happen to be hoarding a nice, shiny, Pearl White pillion seat cowl cover?
lol, unfortunately not. The one on my bike is white, but it's Vauxhall Insignia white. Long story short, not long after I bought my bike I had a full respray in white and the garage asked which white did I want, so I gave them the paint code from my wifes car
