I have been to the Dreal near Toulouse to get the Certificate of Conformity for my Chimaera 450. I have received the certificate, but they have put down that the Puissance administrative is 25cv. I have read that for the 450 it is 19cv.
Has anyone got a copy of their Certificate of Conformity which shows this to be the case?
Thanks.

which year is your Chimaera?
