I don't own one of these, but did have the pleasure of riding one at a Ducati USA and Cycle World event in Northwest Connecticut.
The Ducati Multistrada 1200S
The event was focused on the Diavel cruiser, I chose to ride the Multistrada since it's more my style. Suffice to say, it's a great bike. The Multistrada has the powerful and smooth 1198cc 90 degree V-twin Testastretta 11 desmo engine, and great riding balance and ergonomics. Very comfortable and an absolute blast to ride. And I'd be constantly tempted to drive much faster than the speed limit on every type of road if I had one.....
While both bikes use the same basic engine, the Diavel version develops 162 HP, vice "only" 150 for the Multistrada. Suffice to say that both bikes will get up and go. The Diavel has 3 selectable fuel injection maps -- Sport, Touring, and City. The Multistrada has an additional Enduro map for off-pavement riding.
The Cycle World and Ducati folks had their act together -- tented presentation/tech/lounge areas, free expresso and italian biscotti. If you get an invite to one of these Cycle World & manufacturer events, go!
