Ducks have a mystique to them. As others have posted:
Not many Dealers, so unless you are in a large market for them, you most likely won't see one.
Ducati uses the Desmodromic Valve Actuation System. At a time, it was essential for a high performance motor. With recent advances in manufacturing and materials development, a traditional spring/cam follower design could achieve the same high engine speeds with reliability. Why stay with Desmo valves and the extra maintenance they require? Because Ducati can and it's practically a calling card for them. The maintenance isn't too difficult, but you have to know what you are doing with a Desmo architecture. That's where the high maintenance cost shows up, the Ducati mechanic.
There are bikes that cost less and will perform as well.
There are bikes that owners do not have to consider maintenance costs when making their purchase.
There is the howl of a Ducati and for enough, that outweighs the above complaints. Plus... the bikes look like fine art to me. I'd love to have one. I'd probably never use it to its full performance potential, but I would look good riding it.
Untill then, I'll slug gears on the Yamaha Seca-II
