MV Agusta F4 1000R November 15, 2006

Over the past seven years, MV Agusta’s production has undergone a “style revolution” and the technological progress they have made has further strengthened the MV Agusta image. In the public eye, the motorcycle company has transformed from being a tale of Italian motorcycling legends to become synonymous with beauty, sophistication and technical exclusivity. The thirty-five “Motorcycle of the Year” awards MV have received since 1999 say it all. The specialist judges have also taken into consideration the progress in terms of performance that is in the DNA of all their machines.

One simple example explains everything: since 1999 MV Agusta have increased the power of their four-cylinder engine by 50CV while at the same time constantly improved reliability and reduced emissions. The same applies to our frame department that, while retaining the basic concept of a tubular frame and single rear swinging arm, has continuously worked closely alongside firms like Marzocchi, Sachs and Brembo to create the highest possible specification components exclusively for MV’’s use. The results of this technological evolution are all brought together in the newest creation from MV Agusta - The F41000R. Driven by a pulsating heart the F41000R is the synthesis of all the experience and technologies developed from the F4 project. Adorned in new livery with brand new graphics and colour schemes normally used on Limited Edition models, the F4100R cannot fail to arouse all of those who truly appreciate elite motorcycles that are now fitted with Euro 3 engines.

DESIGN

The design efforts put into the F41000R took three fundamental elements into consideration: character, sporting spirit and quality. The distinctive character of the new MV Agusta shines through the new colour scheme. This third generation look consists of pearl/black/white with black wheels and frame. 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.

The features that distinguish the F41000R are as follows:
- R Graphics
- Silver eco-leather hammer-finish saddle.
- R logo on back of air box
- F41000R logo on tail
- F41000R logo on mirror housings
- Titanium finish applied to: Silencers, Fairing air vents

EQUIPMENT

The F41000R, that in 2007 takes over from the previous F41000S, differs in that it has highly specialised equipment fitted.

The main differences in the R that mark the ‘05 - ‘06 evolution are as follows:

1. Brembo Monoblock P4/34 radial brake calipers.
2. Aluminium Ø320 mm Brembo discs
3. Radial caliper struts
4. Marzocchi USD Ø50 mm R.A.C. forks (Road Advanced Component.)
5. Brembo forged aluminium wheels with Y spokes
6. Integrated Magneti Marelli 5SM ignition-injection system.
7. Raised Perspex screen.
8. Euro 3 engine

One other very important factor is that the engines now meet Euro 3 emission standards.

ENGINE

From the F41000S to the F41000R ‘06, there has been a significant overhaul made to the engines. MV Agusta engineers paid particular attention to creating a new engine unit that differs from previous versions as follows:

- Longitudinal distance between valves increased by 2mm.
- Intake valve angle now 10.15° as opposed to 9.5°
- New bimetallic valves.
- 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.

From the F41000R ‘06 to the’07, the 4 cylinder engine “only” needed technical modifications to meet the new European emission standards with significant changes made to the fuel supply system. Apart from the Magneti Marelli 5SM ECU that was already fitted to the’06 model, a lambda probe was fitted to the exhaust system immediately before the catalyser.

For this reason, the exhaust system is now a one- piece system as opposed to the original three-piece unit. With no joints there is less chance that disturbances in air-flow can affect overall carburetion settings. The F4 is now better prepared than ever to deal with cold starts and offer improved engine uptake. With such high levels of torque and power available, delivery is smoother and this obviously leads to a better ride. The engine has also been fitted with a new secondary air intake system. This unit looks after optimising carburetion in line with triggering the catalyser and making the bike more rideable especially when the throttle is feathered at speeds of up to 120 kph (75 mph) (the speed limit at which emissions are measured for homologation) The filtered air reaches the injector ECU operated solenoid valve via a series of pipes and is introduced into the exhaust manifold where it dilutes exhaust gases and improves the performance of the catalyst. This in turn allows a better use of the air/petrol mix with a richer ratio. The whole system is built into a new profile rocker box cover made from magnesium instead of aluminium.

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 solenoid-activated by-pass valve on cylinder N° 2 intake duct. The by-pass is situated downstream from the feed throttle that has a suitably shaped air intake. This device allows cylinder N°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 in 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.

FRAME

The F4 1000R frame follows the lines of the original one on the “old” F41000S and is still unique today in being 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° and the steering head has been shifted forward by 103.8 mm to further improve handling.

SUSPENSION

The F41000R marks the debut of Marzocchi USD Ø50 mm R.A.C. (Road Advanced Component) forks. These forks are the most prestigious item made by the Bolognese factory. They feature 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 the traditional layout and the Sachs Racing shock absorber with double compression calibration (high-medium speed) and sophisticated hydraulic control of pre-load spring. To complete the picture, the R also has a transversally fitted Ohlins steering damper anchored to the frame to provide symmetrical working conditions.

The MV Agusta F41000R heralds the introduction of a Brembo b system featuring radial P4/34 calipers. This monoblock braking system, derived from competition Superbike and Moto GP machinery has a strut to provide increased rigidity mounted on r adaptors made exclusively for MV Agusta. The enlarged Ø 320mm 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 210 mm disc. The Nissin-designed 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.
