MV Agusta released the all-new Brutale 1000, designed with racing in mind and is closely associated with the F4 RC Superbike, which has proven its potential battling for the top positions in the World Superbike Championship. All the experience that has been accumulated on the racetrack has been poured into the engine of the Brutale 1000 Serie Oro, which sets new records for absolute power while still complying with pollution and noise regulations.
The four-cylinder engine does not betray MV Agusta tradition in terms of technological choice, but it does open a new chapter were materials, design and electronics are concerned. A job that has led to a record peak power of 208 hp at 13,450 rpm with a torque of 115.5 Nm. These incredible levels make this engine one of the most powerful naturally aspirated four-cylinder engines in production.
While remaining loyal to the traditional transverse four-cylinder layout and continuing with the decision to employ radial valve positioning in the combustion chamber along with a central timing chain, unique technical characteristics employed only by MV Agusta, the engineers have revolutionized the original design, leaving only a few castings untouched in the process.
The titanium radial valves now slide through new sintered valve guides and open up into an entirely redesigned and CNC machined combustion chamber. The camshaft timing has been revamped, with the phasing updated on both the intake and the exhaust sides. The pistons use new low friction Asso compression rings to improve performance and efficiency, while the crankshaft was redesigned from scratch and rebalanced to reduce to a minimum the vibrations and resulting parasitic power losses at the high rpm.
To reach the power of 208 hp, the airbox has been entirely reengineered. The careful study of the intake ducts and the use of special resonators allowed the TSS system (variable height ducts) to be removed, thereby reducing the overall weight of the engine by 1 kg while still obtaining an even fuller and more linear power curve. A double injector system – one near the throttle body and the other above the intake duct – provides extremely precise injected fuel management in order to optimize high performance and emissions reduction at any rpm.
A fundamental component of every internal combustion engine is without a doubt the exhaust, custom engineered for the all-new Brutale. The 4-1-4 layout was deemed the best for this type of engine and firing order. The presence of the electronic exhaust valve is useful not only to comply with regulations, but also proves to be fundamental for managing the counter-pressure in the exhaust system to improve engine torque.
In collaboration with Eldor, MV Agusta has developed a new ECU dedicated to the Brutale 1000 Serie Oro four-cylinder. Managed by a full multimap Ride-by-Wire system and regulated by an IMU inertial platform, the Brutale’s riding dynamics are comparable to that of a true Superbike. The inertial platform manages both the traction control and the anti-wheelie system which provides two options: active or inactive. Completing the electronics package are the Launch Control and EAS 2.0 Up&Down electronic gearbox systems, active both in up and downshifting.
While the F4 RC was the starting point for developing the engine in the all-new Brutale, MV Agusta’s heritage is evident in the chassis architecture. Pioneers of the “composite chassis structure” with steel trellis connected to aluminum side plates, MV Agusta has maintained this engineering concept – also applied to the new Moto2 bike ready to compete in 2019 – but evolves it significantly on the Brutale 1000 Serie Oro.
The chassis dimensions have been designed to combine the handling of a naked sports bike with the stability of a super sports bike. These are indispensable requirements, considering the exceptional performance of this naked sports bike, achieved thanks to the unique combination of engine, chassis architecture and aerodynamics. The top speed of more than 300 km/h enables Brutale 1000 Serie Oro to take on models built specifically for racing, also earning the top spot among naked sports bikes.
The braking system is, as always, state-of-the-art with the new Brembo Stylema calipers that grip 320 mm diameter floating discs. Electronic ABS management is entrusted to the Bosch 9.1 ABS system, the most compact and lightweight on the market. The Brutale 1000 Serie Oro comes standard with tire pressure sensors and a Gold Racing chain.
The carbon fibre wheel rims treated with a special transparent red paint contribute to reducing unsprung mass and inertia to a minimum. The presence of an anodized red copper wire in the carbon weave gives it unique visual impact and also contributes to improving the rigidity of the structure. The lithium battery was a must, as well as many CNC machined components. The result is a total declared kerb weight of just an amazing 184 kg.
The unmistakable Brutale design cannot depart from such strongly characteristic elements as the headlight, fuel tank and tail fairing, all of which were custom designed and engineered for this model. The headlight is Full LED and can rely on Cornering Lights, controlled by the inertial platform and able to illuminate turns based on the lean angle, all beneficial for safe riding. For the first time on a bike, the internal part of the headlight unit is colored and forms an “X” shape that the steering base also takes on. The equipment includes front and rear Daylight Running Lights which make the bike clearly visible, even in daylight.
All of the vital engine and electronics functions are displayed on the 5-in. color TFT dashboard with 800 x 480 pixel resolution. The riders smartphone can be connected via Bluetooth to the dashboard to manage incoming calls, texts and music.
