MV Agusta F3 800

The exhilaration of a 1000 cc bike, the handling of a 600. The torque of a twin, the acceleration of a four-cylinder.

The MV Agusta F3 800 pushes back the performance barriers, thanks to Italian-made 3-cylinder engine excellence.

More power, more torque, more adrenaline. The outcome? A motorcycle with exceptional handling, an advanced electronics package and a new 800cc engine that punches out 148 hp and 88 Nm of torque.

Coupled with a super-low weight of 173 kg, the resulting power-to-weight ratio puts it in a position to do battle with litre-class Sportbikes.

The MV Agusta F3 675 redefined the mid-weight Supersport concept by offering up a perfect engine-chassis balance, a power unit packed with quintessential Italian technology and a chassis with class-leading performance on both road and track. The MV Agusta F3 800 goes even further, pushing the mid-range Supersport boundaries all the way up to Superbike replica level thanks to a segment-revolutionising design that is nothing less than a technological and performance milestone.

F3 675 & F3 800

The F3 675 and F3 800 share many new mechanical and electronic features. Improvements to the chassis were also implemented. In particular, the three-cylinder engine benefits from a new frame mount point, which increases torsional and longitudinal rigidity.

EURO 4 HOMOLOGATION

MV Agusta is continuing development of its models by introducing Euro 4 certification across the entire 3 cylinder range. The necessary move from Euro 3 to Euro 4 certification offered an opportunity to carry out some development and technical improvements to make riding the super-sporty MV Agusta even more fun and exciting.

The designers and engineers focused on two objectives: compliance with certification parameters defined by the standard and, in keeping with MV Agusta traditions, maintenance of the exceptional engineering and dynamics its motorcycles are renowned for. Excellent results were obtained despite the very significant reductions in exhaust gas and noise emissions required by the Euro 4 standard. These are reduced by 50% and 48% respectively compared to Euro 3.

ENGINE

Bore diameter remains unaltered at 79.0 mm, while the stroke has been increased from 45.9 mm to 54.3 mm, boosting displacement from 675 cc to 798 cc. Power output reaches a stunning 148 hp at 13,000 rpm, with the peak torque of 88 Nm arriving at 10,600 rpm. The rev limiter has been set to kick in at 13,500 rpm. A double overhead cam timing system with four titanium valves per cylinder gives awesome performance, especially at high revs. Improvements have also been made to the fuel injectors, which ensure higher flow rates than those on the F3 675.

The considerably higher performance – bike mass remaining equal – is highlighted by an augmented power-to-weight ratio (1.17 kg/hp) compared to the F3 675. And that’s not all: acceleration responsiveness has been remarkably improved under all conditions, as has mid-range power delivery smoothness. These two crucial factors mean off-the-scale road riding pleasure and faster lap times on the track.

A full 148 hp of oomph translates into a top speed of around 269 kph, achieved also by way of a final drive ratio that has been raised from 16/43 to 17/41. Lastly, the mechanical slipper clutch system, designed and developed by MV Agusta, ensures tip-top performance however hard you’re braking.

CHASSIS

The same excellence that made its smaller sister bike so successful is, of course, an essential part of the MV Agusta F3 800. For a start, the wheelbase is a mere 1,380 mm, a record-breaking measurement that forms the foundation of this three-cylinder bike’s exceptional handling. The frame is the result of a clever combination of a main ALS tubular steel structure, a mid-section consisting of cast aluminium side plates and an extended swingarm (576.5 mm) designed to maximise traction.

A sophisticated 43 mm Marzocchi front fork – with 125 mm of travel, adjustable spring preload and compression and rebound adjustment – features dedicated settings that let the rider wring every last drop of excitement from the higher-performance 800 cc engine.

The Sachs monoshock provides 123 mm of travel, has a separate piggyback nitrogen reservoir and is fully adjustable in spring preload, compression and rebound. The braking system has been upgraded as well and mounts Brembo monobloc (M4.34a) front calipers to ensure incomparable stopping power even under the most demanding track conditions.

The diameter of the two front discs remains unaltered (320 mm) and the rear brake system retains the two-piston caliper mated to a single 220 mm diameter disc. The F3 800 mounts Pirelli Diablo Rosso Corsa tyres as standard; 120/70-ZR17 at the front and 180/55-ZR17 at the rear.

MECHANICALS

The most important figure is the confirmation of the declared maximum power output: 128 hp for the F3 675, and 144 hp for the F3 800.

ELECTRONICS

The MVICS (Motor & Vehicle Integrated Control System) has been upgraded to improve the ability to achieve the dynamic excellence which has become an MV Agusta hallmark. Engine management algorithms have undergone extensive redesign, enhancing Ride By Wire efficiency. In particular, these improvements concern the relationship between throttle twist and power delivery, which is now more efficient and direct.

Ignition strategy and mapping have been redesigned to improve the power and torque characteristics.

Traction control parameters have also been completely redesigned, giving improved performance whatever the riding conditions. There have also been improvements to EAS 2.0, the electronic up and down assisted gear shifter, which makes gear changes gentler and more precise.

The instrumentation panel, acclaimed for its design and practicality , now includes an OBD light for Euro 4 related diagnostics.

New engine protective covers have been introduced.

These protect the vehicle against collisions or falls and reduce mechanical noise emissions. A thorough study of sound frequencies, aimed at eliminating or at least significantly reducing the overall vehicle noise while amplifying the characteristic sound, has contributed to the preservation and promotion of those frequencies which define the umistakeable MV Agusta “rumble”. These results show how adapting to new regulatory requirements can help improve a product and promote its distinctive characteristics.
