F4 RR

Engine

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 and F4 R 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 hallmark structure and geometry of the new F4 remain unchanged. The frame consists of two distinctive elements, developed by MV Agusta to offer the advantages of two solutions that are usually proposed separately. The main section of the frame, in fact, is made of CrMo steel tubing: this joins to a pair of cast aluminium alloy plates to form a complete structure and provide a pivot point for the sculpted single-sided swingarm. Further frame optimization has reduced weight without sacrificing rigidity. The F4 RR is also hand-welded using TIG technology and uses a dedicated steel with exceptional mechanical properties.

The three versions of the new model offer three distinct combinations of fork and shock, while all provide the traditional F4 handling strengths. The F4 features a 50 mm Marzocchi fork and Sachs monoshock, both fully adjustable. The F4 R has the same fork but a race-spec Öhlins at the rear: again, both units are fully adjustable. As you’d expect, the F4 RR offers up a concentrate of technological excellence and complete personalization: Öhlins suspension with electronic control lets the rider choose between different setups directly from the dashboard.

A different suspension set-up is available for each of the four-cylinder engine maps; however, the rider can also adjust suspension independently of the maps. The system provides separate control for compression and rebound damping, while spring preload personalisation is manual. The electronic steering damper has both a manual and automatic setting, the latter varying its response according to vehicle speed.

Electronics

The MVICS (Motor & Vehicle Integrated Control System) platform integrated on the new F4 ensures precision control of multiple engine maps and rider assistance devices such as traction control and EAS (Electronically Assisted Shift). The central element is the Ride-By-Wire system: first seen on the three-cylinder F3 675, it has now been fully optimized and specifically redeveloped for the new F4.

Electronic redundancy ensures maximum effectiveness and safety: data from the two potentiometers is cross-checked with analogue signals, while a third sensor confirms the complete throttle closure requirement; two additional sensors are installed on the throttle bodies. Completely new – and developed specifically for F4 – is the inertial platform sensor set-up: this uses three gyroscopes and three accelerometers and provides the electronic control unit with an array of moment-by-moment info on vehicle dynamics. Consequently, traction control intervention is particularly accurate, thanks also to an encoder on the front wheel. This is a system that boosts both safety and performance, simplifying the entire riding experience, a key goal of the F4 project. The algorithms that define operation of the MVICS system continuously maximise the available torque at the rear wheel according to both road conditions and the rider’s own demands while electronically assisted gear shift, standard on all three versions, shortens gear changing times.

A further innovation is the Custom map, which lets you choose your own settings as an alternative to the default Normal, Sport and Rain options. This lets you customize five parameters (throttle sensitivity, torque, speed limiter, engine response and engine braking) so you can build up an engine control map that reflects your own individual riding style.

Brakes

The brake system on the F4 RR is state of the art in the hypersports category. It is composed of two 320 mm diameter front discs with steel flanges. They gripped by the new Brembo Monobloc M50; an absolute reference for performance, weight and stiffness with a specifically designed and dedicated radial pump. The system is completed by a four piston rear caliper together with a 210 mm diameter disc.
