Really more digs?Ducatis like the 900 you had look fabulous; there's a few of those here in town. Apparently every single one of them emerged from boxes, and as you pointed out, your 750 Sport (also a fabulous looking bit of Italian dreamwork) is in boxes as I write this. That's where most of them are.
OTOH most of the older Laverdas you see in town have been in service (not boxes) since they were built (to be clear, there aren't nearly so many around). Ducati certainly is one of the few to make the Desmo drive work, but if its about riding across the country (here in the US that can be 1000s of miles) I'd prefer to do it on a Laverda even though some of their parts are harder to find (they vibrate more too), simply because it will hold together (I had both the 750SF2 and a Jarama 1000 triple). Ducatis and Moto Guzzi as you know share the same top end angles between their cylinders so vibration harmonically cancels; i.e. 'naturally balanced'.
