Top of the top of the MV-Agusta range, the F4 1000 RR has everything it takes to shine at the top of the hypersports clan. Among the most important changes are these superb Brembo M50 brake calipers and the now electronic suspension adjustment. Öhlins. The Swedish-made steering damper is electronically assisted or manually adjusted as desired. When the fork and shock absorber duo, there is only the preloading of the rear spring which requires manual intervention. All settings are made from the dashboard. The electronic control unit determines the optimum damping (set by the factory) according to the map selected. But the pilot can also choose his settings in a completely autonomous way.
For all F4s, 2013 is synonymous with a host of small details of varying importance. New LED daytime running lights on the leading edge of the air intake, lightweight wheels, rebalanced crankshaft, titanium connecting rods, variable intake, redesigned oil and exhaust system, new shifter , valves recalled by a single spring (two previously) and an update of the on-board electronics.
Among the sportsmen of Varese, the RR sings a melody raised by one octave. It is no longer enough for him to be the most desirable; she also wants to be the most powerful, the most noticed, and to be able to give back a dose of dreams in a battered category yet kneaded with excellence. And then there is this equivocal name: CORSA CORTA. Short course in Italian. What to explain in two words that a new engine has taken place in this sporty MV. A boiler which, you will understand, benefits from a shorter stroke of the pistons in their cylinders. But to make it a powerful mechanism which now exceeds 200 horsepower, the Meccania Verghera has not skimped on the transformations of the 4 cylinders..
In 2010, the block of the F4 had already evolved a lot, spewing more than 185 horses. The manufacturer wanted to offer it more than 200 horsepower, and had already done so on the 1080CC, by increasing the displacement (and greatly the price). But to be able to get involved in competition, there is no question of exceeding the liter. So, to find power, the engine manufacturers changed the internal dimensions, various parts, and went to look for watts in the rpm. This short stroke is 50.6 mm, against 56 previously. The bore takes the opportunity to climb from 76 to 79 mm. With its new values, the linear stroke of the piston is 22.9 m / s. A speed not only reasonable for mechanical reliability, but also down compared to the engine of the standard F4 1000 (24.7). Very super-square sides, this is well in line with an engine speed which is now approaching 14,000 rpm. The F4 1000 RR spits out its 201 horsepower at 13,600 revs, and pushes back its red zone to 14,000 revs.
Wider combustion chambers, it allows to fit larger valves. On the intake side, their diameters increase from 30 to 31.6 mm, and from 25 to 26 mm at the exhaust. Even if it means changing the valves, you might as well make them in titanium. With the new exhaust line with larger collectors, an injection of 49 mm and the admission at variable horn height, the boiler breathes hard, very hard. To channel it, the ECU offers you a choice of two maps and an 8-position anti-slip. Still on display, the gearbox is of the cassette type and is assisted by an anti-dribble clutch. In short, it smells like a Superbike..
Big horses, it allows to weld and with big heart. But a MV with two Rs, it must be riveted to the floor. The base does not change, the RR taking over the chassis of the F4 … but optimizes it as desired. Already, you can change the height of the rear axle and swingarm via a set of calibrated parts. For the ground connections, the best do not ask the question and will equip themselves on the side of Sweden. Under the chin, it shines, and it’s Öhlins. A 43 mm NIX fork adjustable from anywhere, with a particularity: compression is adjusted on the left leg and rebound on the right. This ensures more precision during adjustments because one does not influence the other. The rear shock absorber is a TTX36, adjustable in compression, rebound, preload, and length in order to vary the attitude of the machine. Braking? All radial, from the master cylinder to the calipers, Brembo and monoblocs because we can only design the best for this super F4. Hey, by the way, we’re going to change the wheels and put on forged aluminum rims. It will save 1 kilo and improve agility. But even with that, you will still have to hold this RR CorsaCorta. With a nuclear reactor as the engine and a surgical frame as much as it is rigid, the F4 1000 demands that we take care of it, that we force it to stay on course. Quite the opposite of a Japanese woman who accompanies you in the job. On the other hand, on the precision side, it’s like the whole machine: haute couture.
Its suspensions are tools … Its engine is the most powerful … Its line is sublime … By disembarking, the F4 1000 RR Corsa Corta can already put blows in the dimensions of the formidable ZX-10R, S 1000 RR and RSV4. Demanding, uncomfortable, she sweats competition while leaning towards the object of art. Its place is also more in a circuit or a show than on the open road.
