The chassis is one of the foundations which has made the original MV Agusta F4 unique and unmistakable. An extremely rational and light structure which is characterised by the union of a steel lattice structure coupled with aluminium side plates. This frame design has influenced a generation of frame designers which have continued to imitate the MV. The new F4 remains loyal to tradition and offers a similar tubular construction but it exceeds the originals characteristics in both rigidity and lightness. A complete redesign of each of the individual components, including the wall thickness and diameter of the tubes coupled with the cast side plate design, contributes to the reduced weight and increased torsional rigidity.
The new chassis is narrower, shorter and lighter. The area of the steering stem has been completely revised and the side plates have been moved forward, this has allowed an optimal weight distribution (52% front, 48% rear). The repositioning of the rear swing arm pivot has enabled MV to improve the traction of the rear wheel without increasing the wheelbase. The steering stem continues to offer the possibility of regulating the inclination of the steering by rotating the inner element.
The standard inclination is of 23° 5´ for a nimble, modern and effective ride.
Every component has been made compact and has been optimised to be adapted to the new layout of the motorcycle. The rear suspension linkage ratios have been re-designed and have a new curve which is more progressive, the rear sub frame has been completely redesigned and is both more compact and lighter.
The single sided rear swingarm is a real engineering jewel, it has been extended by 20 mm compared to the previous one which contributes to the increase in the rear wheel traction by optimizing the chain torque reaction. The redesign of the rear swing arm assembly has drastically reduced the weight by 1,2 kg (2.65 lbs) while maintaining the same level of torsional rigidity. The front fork of the new F4 weighs an incredibly low 5 kg (11.02 lbs) which sets a new standard of low weight in the superbike class. The complete redesign of the hub of the rear wheel also contributes to the weight reduction and optimization of mass cetralization.
As every other technical feature of the F4, the suspension is also considered the best in class. They have been manufactured to specific MV standards and offer increased ride control, effectively connecting the tire contact information directly to the rider. The upside down Marzocchi fork with a tube diameter of 50 mm continues to contribute to the MV tradition of uncompromised stability. These forks are direct descendants of our championship winning race bikes and they offer adjustable spring preload, compression and rebound damping. The extremely light forged axle carrier has also been produced on solely for F4. The axle carrier utilizes a system quick release of the front wheel similar to the systems seen on endurance racebikes, recalling the solution first seen on the mythical F4 Serie Oro.
The single rear shock is supplied by Sachs and is equipped with nitrogen "piggy back" reservoir tank (integrated into the body) and has adjustable rebound, compression and spring preload settings. The rear link allows the possibility of raising or lowering the rear end of the motorcycle in order to help adapt the bike to the personal preferences of the rider and the track.
The Brembo front system with radial monobloc callipers is without a doubt the best system on the market. On the F4 it is joined to a Nissin pump with integrated reservoir and produced to specific MV standards.
The 320 mm diameter double floating steel disc of utilizes an extremely light flange and a reduced 5 mm thickness in order to reduce the inertia and unsprung weight to an absolute minimum.
The rear brake system is produced by Nissin exclusively for MV with a 220 mm diameter stainless steel disc and a four piston caliper.
ATTENTION TO DETAIL
Excellence in every component
What characterizes and distinguishes the MV Agusta F4 from the rest of the super-sport motorcycles is the relentless attention paid to every single element and detail. The care taken when analyzing every single detail is not only aesthetic, but it helps to contribute to the increase in performance, reduction in overall mass as well as maintaining the ultra high standard of fit and finish found only on MV Agustas.
The optimization of the new F4 has effected every single component and aspect of the bike with a single goal: un-relentless pursuit of weight reduction. In some cases the results are easily identified, for example the fuel tank is visibly shorter, lower and more tapered than before. It has been produced in rotational nylon which has allowed us to reduce the weight of the tank itself by 1,2 Kg (2.64 lbs).
The cast wheels maintain the characteristic MV ôstarö design but the style is without a doubt more advanced. They have been optimized in their design and are 1,2 kg (2.64 lbs) lighter compared to the previous units.
The dashboard of the F4 is not simply a display where data can be read, but it is the digital interface between the rider and the motorcycle.
The dashboard uses CAN line technology to reduce the wiring harness to a minimum, also contributing to the reduced overall mass of the motorcycle. With the application of this technology MV Agusta has once again introduced a new standard to which other manufacturers will have to adapt. The dashboard, completely digital, uses digital matrix technology which offers perfect integration and instant response from the digital data display. The dashboard is very light, it offers a tremendous amount of data including vehicle speed, engine rpm, gear map, Traction Control level and lap timer for use during track events.
The maniacal persuit of weight reduction has led to the redesign of the superstructure. The result is a reduction of 3 Kg (6.61 lbs) of the fairing and 300 gr (4.8 oz) from the plexiglas windscreen. The motorcycle has been improved in every single detail with a single goal in mind: to be the best.
The optimization of the project has also focused on secondary systems like the ignition key mechanism and the fuel cap. The key mechanism, now incorporates an electronic immobilizer, makes it difficult to start the motorcycle without the owners key.
MV SPECIAL PARTS
To make it unique.
Advanced technology and styling are core components of the MV Agusta DNA, clearly visible in the new F4; however as we believe that limits exist only to be exceeded, we continue to design components that help make the F4 even more unique. The list of the MV original special parts has no end, special materials and technological components of the latest generation allow you to increase the performance of new F4 even more as well as the possibility to personalize it aesthetically.
Visit the website www.mvagusta.it and make "your own" F4 thanks to the special 3D configuration which allows you to preview the personalized motorcycle.
The quality of the MV special parts are a guarantee for the customer. The same attention to detail in design and materials applied to the productionF4 has been utilized in the design and production of the special parts. These special parts components have been produced with precious materials such as titanium and carbon to reduce the weight of the F4 even further.
The racing exhaust system coupled with the dedicated ECU can release all of the anger of the 4-cylinder, radial valve MV engine. MV Agusta accessories, like MV Agusta clothing, can be previewed and purchased on-line on the website www.mvagusta.it.
