Hi Mello dude,
Radiator is under the seat, designed that way to streamline the front end of the bike. Ducts at the front channel air through (thru guys) to the radiator drawn in by the rear mounted fans. Always lots of questions whenever you stop anywhere, particularly about the fans. The engine is Benelli's 900 cc triple, developed back in the late 90's, the bike then was their attempt to get into world superbike. By the time it got there, I think 1999?, the class had changed to 1000 cc. Needless to say it didn't compete again so Benelli decided to launch it as a road bike. Only 1539 of the 900 tre were made plus some RS models, 150 limited edition bikes and they also did an 1130 cc version.
But hey, isn't this a Vfr forum? :)
