Just looked at the fiche and it is the oil cooler pipes. If you contact a Honda dealer and tell him you want the inlet and outlet pipes for an oil cooler, he should be able to call up the same picture you're looking at and relate it to a second fiche with the part numbers and prices on.
To identify your bike, remove the seat and read the label underneath. It should say XRV750 and then an identifying letterprobably a W,X or Y. The dealer will need to know that.
