The 2014 MV Agusta F3 - 800 will be introduced in June.
The F3-800 will be a larger version of the F3-675. The inline three cylinder engine of the new bike should be the same with that of Rivale and Brutale, although it is expected to be much more powerful than the 123 bhp/11600 rpm and 8.3 kgm/8600 rpm (60 ft lbs/8600rpm) nominal delivery of that engine. A 140 bhp figure is a fair guess. This was also the case with the F3-675 compared to Brutale 675.
The frame and electronics should be the same with the 675 version. The weight should be about the same also, 167 kg (368 lbs) nominal dry, while the price could be about 14000 Euros.
Comment: The three cylinder engine layout as it has been successfully featured by Triumph in the last 20 years becomes a trend among the manufacturers (MV-Agusta and Yamaha for the time being).
