No chance that the airbox will fit, the 600 hybrid engine sits too high in the frame so there isnt clearance between the frame and engine for the airduct to fit for a start, plus the airbox should fit flat on the sides of the frame and as the engine is higher it wont. Ive looked at this myself as I have a 400 race bike with bdk airbox and a hybrid and its not worth the hassle. Without cutting the frame I cant see how ramair can be fitted to a hybrid but I'd be interested if anyone has any ideas?
