Reducing the existing FZ-09's engine capacity to 675cc, where it would be eligible for racing, would be relatively simple. The engine's 78mm bore is already perfect for a 675cc triple (the MV F3 uses a 79mm bore), and the stroke would only need to come down from 59mm to 47mm to reach the right capacity. Shortening the stroke would also allow more revs to make up for the lost displacement, potentially allowing a 675cc R6 triple to make more power than the 115 bhp FZ-09, just as Triumph's Daytona 675 out-punches the bigger, lower-revving version of the same engine that's used in the Tiger 800. It's worth mentioning that the original CP3 engine concept was noticeably different in appearance to the one that eventually appeared in the FZ-09. The concept shared many design elements with the R1's crossplane four-cylinder, hinting that it could be intended for a supersport bike.
