RR, the magical acronym that immediately brings to mind the world of competition. The bike for special individuals who demand the most exhilarating riding experience. Created using the most exotic materials, ultra-sophisticated suspension and the new 1000cc short-stroke engine make the MV Agusta F4 RR the most advanced and powerful superbike in the world.
When the most sophisticated chassis design is joined with the new MV short stroke engine, the result can only be an extraordinary machine. The MV Agusta F4 RR is the perfect tool for riders who demand the utmost performance. Evolved, exotic, and even further refined, the F4 RR is currently the best that technology can offer to the motorcycling world. To already refined MV Agusta F4, you add even more exotic materials, reduced weight, and, above all, a 201 hp four-cylinder engine which makes the F4 RR the most powerful superbike ever built. All “packaged” with the advanced design that makes the MV Agusta F4 RR unique and unmistakable.
A project for those who demand the ultimate riding experience.
ENGINE: 201 Hp, PURE POWER
The new 4-cylinder short stroke engine with radial valve is the soul of the MV Agusta F4 RR. The engine is completely new and is inspired by MV Agusta’s experience in competition. Apart from the engine case castings, the arrangement of cylinders and a few other elements the 4 cylinder RR engine shares little with that of the previous F4. It has been completely redesigned with a single goal in mind: maximum performance. All new thermodynamics, a new crankshaft that has a reduced value of inertia and new bore and stroke dimensions with an extremely over-square relationship that can reach rpm’s worthy of a true racing motorcycle. The piston diameter has been increased from 76 to 79 mm while the stroke is reduced from 55 mm to 50.9 mm. With these dimensions the rpm limit has been raised to a stratospheric 13,700 rpm while at the same time reducing the linear velocity of the piston (from 24.7 m/s to 22.9 m/s) and thus also improving reliability.
To reach the stratospheric level of 201 hp at 13,400 rpm with a completely homologated engine including an exhaust system complete with the catalytic converter, extreme attention has been given to every detail. The thermodynamic efficiency has been optimized to guarantee a record level of performance. For this reason, the head of the F4 RR is completely new including new intake and exhaust tracts as well as large diameter intake and exhaust valves. For the first time on an MV mass production engine, all the valves are made of titanium and this has made it possible to reduce the mass while at the same time significantly increasing the diameter (30 to 31.8 mm for the inlet and from 25 to 26 mm for the exhaust). The tuning of the engine has been optimized thanks to the use of a completely new 4-2-1-4 exhaust system with large diameter tapered headers. In addition to ensuring the optimized performance of the engine, this new exhaust system has a unique sound and is even more intoxicating. The intake is controlled by four 49 mm throttle bodies with the unique TSS system of variable length intake tracts.
The new engine of the F4 RR has been designed according to the criterion of low friction. A new primary drive gear has drastically reduced the speed of the generator and water pump in effect limiting the parasitic power consumption of these components. As with previous F4’s, this new engine features a rapidly removable cassette gearbox and the clutch employs a mechanical slipper system to assure proper control even under the most extreme braking conditions. The electronic engine management has been further refined compared to that of the previous F4. The traction control follows new operating modes as well as two maps for the engine, and everything is now easily managed through the new controls that have been placed on the left handlebar.
CHASSIS: LIGHT AND PRECISE
The frame and swingarm are common with those of the already excellent F4, but the desire on the part of MV Agusta to offer a four-cylinder superbike has also led to the employment of some unique solutions. To optimize performance and adapt the F4 RR to all race tracks and conditions, the MV Agusta F4 RR allows a virtually infinite combination of adjustments. Multi-adjustable suspension, essential for a racing motorcycle, has been combined with the adjustable steering head angle (with interchangeable eccentrics) and the height of the swing arm pivot and rear axle by means of calibrated inserts.
SUSPENSION: THE BEST OF THE BEST
The Öhlins NIX upside-down front fork has 43 mm diameter inner tube and a titanium nitride coating to improve the smoothness and precision. This particular fork dimension has been designed to achieve the perfect balance of agility without sacrificing the legendary stability of an MV.
As the most sophisticated motorcycles, the front wheel axle carriers are machined from billet aluminum and the front forks offer precise external adjustment of spring preload as well as compression and rebound damping. Also, the fork of the MV Agusta F4 RR provides separate adjustments for the hydraulic damping (left leg compression, right leg extension), a solution that enables the accuracy of the hydraulic independence as varying the compression does not have an influence on the rebound.
