2004 MV Agusta F4S1+1

Cloned from the unrepeatable F4 Serie Oro,the S having an excellent price versus quality ratio, it represents the entry level to live the pleasure of owning an F4. Available in the commemorative chromatic red and silver version or in the luminous "Diamond" colour, the F4S is produced as both a single or double seater.

In this latter version, named 1+1, the passenger seat was obtained with the intention of maintaining unaltered the stylistical flow of the spectacular arrow type tailend. In achieving this objective, the passenger seat is the same colour as the bodywork and the relative footrests are designed to integrate themselves perfectly within the extraordinary F4 lines.

The modifications of the Model Year 2004

The Chassis:

The frame of the F4 is universally considered as the absolute technical benchmark in the motorcycle field.

Designed to guarantee maximum access to all mechanical components and to give rock solid torsional rigidity, it is characterized by a mixed structure of chromium molybdenum steel tubes and swingarm support plates in aluminium. Connected to these is the rear suspension's rocker arm and the rear subframe which is made of aluminium tubes. Both the trestles for the frame and rear subframe are produced entirely by MV AGUSTA.

The detail that most captures the imagination of the passionate is surely the sculpted single swingarm. A structure that for rational conception and visible impact has become the manifest of creativity and expertise of CRC's technical staff. The dialogue between the frame and front suspension occurs by means of a Showa upside down fork with legs which are 49mm in diameter. The the F4 also boast the Sachs shock absorber with double regulation for compression.

The F4 are equipped with a Ohlins steering damper placed transversally with respect to the direction of motion. This component is fixed to the frame on both extremities in order to function symmetrically. Particularly seductive are the steering plates; the upper has a prismatic diamond shape whilst the lower presents a bridge-like frontal view which improves the air flow to the radiator. The front brake system is comprised of two exclusive "Nissin F4" six piston calipers with differentiated diameters, and 310mm diameter disc brakes.

The clutch and Nissin front brake commands boast the patent of the lowered position hydraulic fluid containers aimed at obtaining a complete visual of the instrumentation which includes a clock.

The engine

Characterized by a design coherent with the legendary 500 GP bikes of the past, the four cylinder inline with double overhead camshafts has undergone a series of important updates which have been introduced to increase the already impressive amount of power and torque. The improvements carried-out by MV AGUSTA's technical staff were developed through the introduction of the following modifications:

• Malhe stamped pistons
• Malhe cylinder block
• Crankshaft lighter by 1kg
• Redesigned combustion chamber
• Exhaust valves with flat head
• Valve springs with variable step
• Jets for cooling the underside of the pistons
• Modified clutch hub aimed at increasing its resistance
• New exhaust manifold 4 in 1 in 2 equiped with compensators
• New ratios for the primary and final drives
• New oil filter and relative fixing system

The refined technical features remain unaltered which make this MV AGUSTA propulsion unit the most exclusive four cylinder inline engine in worldwide production, like the radial valves or the exceptional removable gearbox derived from Cagiva GP.
