Someone I know has a friend who has a Ducati.
Not ragging on ya but that is some real first hand info.
The two bikes in question are 2 completly different animals. Never ridden a speed triple, but I would expect it to be close to an inline-4 in the power dept. Maybe a tad bit more low end, but an inline at heart. May as well buy a GSXR.
On the other hand, the 2v air cooled 1000 DS (dual spark) ducati motor is a breath of fresh air. I have a 900ss (carburated 1992 model) to compare even though the 1000DS is better all around.
The air cooled Ducati's, both SS and Monster, are light and extremely flickable but are not overpowered. It is a totally different ride. The 1000DS makes around 85-90 ponies at the rear but lives between 3500-7500 rpm. Linear useable power throughout this range. Effortless to ride. With premium rubber you will be thinking you are a Superhero in the twisties.
Maintence is very liveable on the 2v motors, belts and valves every 12,000 miles or 2 years runs around $350. Valves alone every 6000 run around $225.
The clutch is a little stout, after a few weeks you will be crushing walnuts with your left hand
Aftermarket parts galore for the Monster also. How many bikes sound like this:

BTW, NAPA sells fuel hose by the linear foot at a slightly better price than the quoted amount above.
Good Luck, Ed.
