it's not overpriced. It's a darn close replica of an actual motoGP bike. Aside from HP, you're getting the best handling components, race ready bodywork, a 200 rear Bridgestone racing tire made exclusively for the Desmo, an onboard laptimer that utilizes GPS trackmaps (no transponder and Infrared beacons needed), and more. Just a full on race ready package suited mainly for the roadrace/Ducati conneisseur or collector.
One of the instructors for Freddie Spencer's riding school and columnist for Cycle World rode the Desmo at Miller Motorsports Park and was VERY IMPRESSED with the power delivery, handling, and how scary close it is to an actual MotoGP bike. He still said, that with MMP's elevation, the Desmo's top speed on the 3700 ft straight was still a few MPH down on the AMA superbikes--but not by much.
