These are my 2 bikes with the same shroud graphic (the Graphic is Factory Honda Limited Edition Tribal Flames) , again , it might depend on the design of the graphic as to weather you can trim it without compromising the design of the image
Again , this is a 06 450X and a 02 450R with 08 450R Limited Edition Graphics, so the shrouds on all 3 bikes are different from each other in bolt placement and shape , but i was able to make the graphics work , this is not always the case , so its not a 100% guarantee it will work in your case , just saying it "can" work with "some" graphics
