The new MV Agusta F4 R 2012 has been designed to offer clients a superbike with extreme performance. The key feature of the F4 R is, in fact, the new “Corsa Corta” engine capable of extraordinary performance and already employed on the F4 RR, the top of the MV Agusta superbike range.
The new 4 cylinder inline with radial valves is the pulsing heart of the MV Agusta F4 R. The thermodynamics have been completely redesigned, starting from the new low inertia crankshaft which makes it possible to use a super over-square bore and stroke ratio. In this way, the MV F4 R is capable of reaching rpm worthy of a pure racing motorcycle. The engine capacity of 998cc has been obtained by using a bore of 79 mm and a stroke of only 50.9 mm. In this way it is possible to achieve an extremely high 13700 rpm rev limit while at the same time lowering the linear velocity of the piston from 24.9 m/s to 23 m/s improving reliability. (more…)
