I was wondering if motorbike parking is free in Paris as it happens to be in, for example, Madrid.
I also read about parking on the pavement on this page:
"Parking of two-wheeled vehicles on the pavement is tolerated, as long as you are not blocking the way for pedestrians."
Though they recommend not to do it, I don't know how old that information is.
EDIT:
In case you want to park on the street, can motorbikes park on the bays supposed to be for cars? or shall I look for an specific motorbike spot?
