Hi Ian, you might struggle finding a new one for her, most manufacturers of aftermarket parts only do them for a couple of years after production stops. QB carbon used to be our go to for this sort of thing so might be worth giving them a call?
RSR do them in matte: https://www.rsrmoto.com/ducati-600s...on-fibre-rear-hugger-chain-guard-plain-matte/
Mines damaged on the bolt tab but @Sev has recommended Speed Carbon in Italy, as they've the original moulds / forms from the previous campany. #Sev's offered me one from his stockpile
