Spent the last week refinishing both the 906 and the 907 due to a few unfortunate incidents thought I'd pass along a few things I've found
For the 906 Duplicolor Torch Red is a ringer for the Lechler Rosso and can even be found at Walmart when you can find it at all
I had a guy at National Auto round me up 5 cans..........5.99 in a 5oz can One can is enough to do two mirrors and a side panel and will add an interesting tint to the back of your wife's hair( ) if you prep it properly with a white sandable primer( the bike parts not the wifes hairdo )

For the 907 Duplicolor Cardinal Red (8oz can)appears to be pretty close, have not clear coated it yet so the jury is still out on this. Cardinal Red can be found anywhere Duplicolor is sold, Pepboys,Walmart almost any auto supply house carries Duplicolor

For Decals These guys rock............

Complete kits or individual decals can be had ( bring your wallet ) Cover all Ducati's and even have the coveted 'Red Duck'

I found this is very good match f 907:

that`s because in Germany RH Lacke has the monopoly and sells the original paint.
