REVIEW: MV AGUSTA F4 1000R

The newest creation from MV Agusta: F4 1000R. Driven by a pulsating heart with torque and power (+10CV) that the previous F41000R could only have dreamed about, the new model is the synthesis of all the experience and technologies developed from the F4 project.

Adorned in new livery with brand new graphics and colour scheme normally used on Limited Edition models, the F4 1000R cannot fail to arouse all of those who truly appreciate elite motorcycles.

The complete engine, suspension and brake package has undergone a radical performance-orientated evolution leading to the introduction of a radial braking system, forged Brembo wheels and new Marzocchi forks.

The features that distinguish the F4 1000R are as follows:-

The design efforts put into the F4 1000R took three fundamental elements into consideration: character, sporting spirit and quality. The “distinctive character” of the new MV Agusta shines through the black “Bodoni” livery that is broken by a double red graphic tapering from the tail to the front mudguard and creating a soft curve that suggests speed and agility. The perception of quality is highlighted by a combination of the finish applied to technically evolved components and the brilliance of the paintwork that enhances the overall look.

Silencers.

Fairing air vents.

THE EQUIPMENT

The F4 1000R lies between the F4 1000S and the limited edition F4 Senna. In relation to the “S”, it features more specialised technical components not to mention innovations to the engine.

3. Radial caliper struts.

4. Marzocchi USD 50mm diameter R.A.C. forks (Road Advanced Component).

5. Brembo forged aluminium wheels with Y spokes.

6. New integrated Magneti Marelli 5SM ignition-injection system.

7. New raised Perspex screen.

8. Rear Mudguard.

9. Battery Charger.

After three seasons of more than honourable service, the 998cc block introduced on the F4 1000S has been given a serious re-working.

MV engineers focused on creating a new heat dissipation system that differs from previous arrangements as follows:

Longitudinal distance between valves increased by 2mm.

New distribution layout with less crossover between intake and exhaust.

New Mahle block with bores moved 1.5mm towards the rear of the engine.

New forged pistons with renewed graphite coated skirts.

New intake duct geometry.

New aluminium clutch bell housing.

New larger two-plate clutch.

The electronic engine management system features a series of important innovations starting with the new Magneti Marelli 5SM system that replaces the previous 1.6M.

This system is much more compact than its predecessor and if fitted with a FlashEprom memory unit, the 5SM phase sensor works in concert with the exhaust camshaft making sequential injection possible. On previous generation machines, such an arrangement was unheard of. Each cylinder has been supplied with an individual “plug top” coil with consistent improvements in terms of engine output.

The Magneti Marelli 5SM ECU manages the widely acknowledged EBS system (engine brake system) that is fitted to MV Agusta engines for controlling torque under deceleration. The concept is based on a solemoid-activated by-pass valve on cylinder No.2 intake duct. The by-pass is situated downstream from the feed throttle that has a suitably shaped air intake.

This device allows cylinder No.2 to produce torque even under deceleration (when the feed throttles are closed) thanks to a signal sent by the Marelli ECU.

Looking at the diagram, the advantage on terms of engine braking at high and medium engine speeds is self-evident. It is also very clear that the engine management system could allow more demanding riders to adjust and optimise engine braking at different engine speeds to suit their individual riding styles.

The frame on the new F4 1000R follows the same pattern as the F4 1000S and is still the only frame in the four-cylinder production category to be made from chrome-molybdenum steel tubing. This solution offers considerable advantages in terms of compactness, mechanical access and torsional rigidity. The frames are built in their entirety at the MV Agusta plant in Morazzone.

The tubular structure unites the swinging arm pivot plates where both the rear swinging arm and the saddle support bracket are connected. The sculpted single swinging arm, apart from its superb style, was created by the CRC engineers as much for its beauty as for its unmistakeable technical efficiency. The steering angle now lies at 24.5 degrees and the steering head has been shifted forward by 103.8mm to further improve handling.

THE SUSPENSION

The F4 1000R marks the debut of Marzocchi USD 50mm diameter R.A.C. (Road Advanced Component) forks being fitted to a production bike. These forks are the most prestigious item made by the Bolognese Factory. They featur a multi-adjustable unit (13 compression settings and 32 for rebound) fitted with carbon nitride treated uprights designed for improved slide characteristics.

The looks also differ in the anodised stays that add to the individuality of this specific model. The rear suspension uses both traditional layout and the Sachs Racing shock absorber with double compression calibration (high-medium speed) and sophisticated hydraulic control of pre-load spring. Like on the F4 1000S, this new model also has a transversally fitted Ohlins steering damper anchored to the frame to provide symmetrical working conditions.

THE BRAKES

The MV Agusta F4 1000R introduces the use of Brembo brakes with radial P4/34 calipers. These monoblock units, derived from Superbike and Moto GP machines, have a strut to provide increased rigidity mounted on radial adaptors made exclusively for MV Agusta. The enlarged 320mm diameter discs with steel braking area and aluminium flange are also new.

The rear brake remains an unchanged four-piston (opposed) caliper unit acting on a 210mm disc. The Bissi-made front brake and clutch levers are exclusive to MV Agusta and can be micrometrically adjusted. The Brembo forged aluminium wheels with Y spokes measure 3.50″ x 17″ at the front and 6.00″ x 17″ at the rear.

Tyres are 120/70 ZR 17 up front with 190/55/17 at the rear.
