Is it true that Ducati changed the belt part numbers on the belt kit to the same numbers? I have read in a few locations that in 2017 they went from 737.4025.2A and 737.4025.1A to just 737.4025.2A for both? Is this correct?
Well, apparently they have in fact changed the part numbers and both belts are now the same. Also, red lettering indicate they are the new/better kevlar design that last longer and the blue lettering indicates they are the old belts.
