Shortly after showing off its new 2010 Brutale naked streetfighter, iconic Italian motorcycle manufacturer MV Agusta will unveil its range-topping F4 sportbike at the EICMA motorcycle show. MV let loose one teaser image early last month, but details are just now starting to leak out about the 998cc inline-four screamer.

According to OmniMoto in Italy, MV Agusta has massaged its well-known powerplant with twin fuel injectors per cylinder and variable throttle bodies to put out 186 horsepower (still short of the class-leading 193-horsepower BMW S 1000 RR) at 12,900 RPM. Also on the menu are a slipper clutch and eight-way adjustable traction control.

We don't expect major chages to the bike's already attractive overall design, but a new bi-xenon take on the vertical headlight will join a longer and lighter single-sided swingarm to update things a bit. In any case, we'll get all the details soon enough when the F4 makes its official debut next week in Milan.
