MV Agusta F4
Timeless. Limitless. The F4 is now even faster and more
powerful. Exclusive. Unique sensations and the most advanced technologies Features
Pure performance An advanced four-cylinder ‘short-stroke’ engine powers the entire F4 range. Piston diameters of 79 mm are combined with a stroke of 50.9 mm. On the F4 RR the peak rev limit has been raised to 14,000 rpm. Assembly is now marked by an even greater degree of expert craftsmanship to give absolute precision, with all components being selected and measured to ensure perfect uniformity and maximum performance: a procedure unique to MV Agusta. The engine timing system has been given an extensive upgrade: the intake and exhaust valves now use a single spring instead of the two seen on the previous model, thus reducing moving mass and boosting both maximum engine revs and the rev variation rate. The piston blanks are hard-anodized, making them even more durable and reliable. The con rods on the F4 RR are made of titanium, a solution more akin to a GP racer than a production machine, giving improved strength and lightness; the engine also features a rebalanced crankshaft. The oil circuit has been redesigned, both inside and outside the crankcase, ensuring perfect main bearing and con rod lubrication and thus boosting reliability, even under extreme conditions. Moreover, the engine now runs at lower temperatures thanks to enhanced radiator efficiency and redesigned oil routing. The short-stroke inline four-cylinder engine is available in two power configurations: on the F4 it reaches 195 hp, while the F4 RR puts out a jaw-dropping 200.8 hp. The fuel delivery system features 50 mm diameter throttle bodies with a fully revised variable length intake tract (TSS). The gearbox is - as on all MV Agusta four-cylinder engines - a six-speed unit, with the clutch featuring a mechanical slipper device. Four engine maps are available: three default one plus a fourth that can be customized by the rider.
Design The personality of the F4 has now been sharpened even further by
combining a design solutions with distinctive features that have already seen
the F4 walk away with countless best-looking-bike awards. Now details boost its
appeal even further, this time with light playing a key role in the choice of
new graphics and color and, of course, in headlight and tail light design. The
front headlight is flanked by two distinctive ‘light guides’ on the leading edge
of the spoiler, thus making an aerodynamic part essential to the bike’s frontal
look, both day and night, and boosting safety by improving frontal visibility.
Similarly, an integrated light guide increases the brightness of the rear light
assembly. Completely wheel designs offering considerable weight reduction are
available in two versions. The first, on the F4, utilizes razor thin spokes and
a silver finish. The second, on the F4 R cuts weight and material thickness even
further thanks to a special aluminium alloy forging process and offers
attention-grabbing race-inspired design. There has also been a significant
upgrade to the four-tailpipe exhaust system, a characteristic feature of the F4
ever since its inception. The two outer pipes are now much shorter and tapered,
while the central pair extends beyond the end of the tailpiece. Making the F4
even racier - and lighter - than ever.
