1299 Side Panel Stickers, Size?

I don't know the answer, but you could phone a Ducati dealer to ask if the new (2015) Panigale R decals are the same part number as the 2013 1199 Panigale R ones to confirm, or get hold of the parts lists for both bikes and compare them yourself. I would expect them to be the same though

 

they are 27inches .065432mm long the 1299 is o.0004532167mm shorter
