The MV Agusta F4 was the motorcycle that launched the resurrection of MV Agusta in 1998. The F4 was created by famous motorcycle designer Massimo Tamburini at CRC (Cagiva Research Center), following his work on the Ducati 916. The F4 is unique with its four pipe undertail exhaust, single-sided swingarm, large front forks (49 or 50 mm diameter) and traditional MV Agusta red and silver livery. The F4 is also one of the few production superbikes to have hemispherical chamber 4 valves per cylinder engine.
The F4 engine is a liquid cooled inline four cylinder (4-stroke) with two overhead camshafts (DOHC), 16 radial valves, electronic multipoint injection, induction discharge electronic ignition and following capacity variants: 749.5 cc, 998 cc and 1078 cc. The engine was derived from the 1990–1992 Ferrari Formula One engine. Early in the design process Ferrari engineers assisted in the development of the engine. MV (Cagiva at the time) quickly deviated from the Ferrari design, but they kept one important feature, the radial valves. The F4 engine is unique in the sense that it is the only radial valved motorcycle engine currently in production.

Let us Discuss the Various Versions of the F4 Series :
F4 750 Serie Oro
The first F4 model released to the public was the F4 750 Serie Oro on May 1999. Only 300 examples were produced. Many parts such as the swingarm, frame side plates and wheels were made from magnesium. These magnesium parts were anodized gold for consistency with the name 'Oro' (Italian for gold). All painted parts, such as fairings, seat cover, front mud guard and even the fuel tank and air box are made of carbon. It's only by using these materials that the weight could be kept under 400 lb which is only beaten by the F4 Veltro. The specially for MV Agusta developed Showa fork has fast detach axle clamps. The six piston (front) and 4 piston (rear) brake calipers are made from Nissin. MSRP $57,000
F4 750 S
The mass production model, the F4 750 S (S = "Strada"), was released in 1999, and was essentially the same bike as the F4 750 Oro but with aluminium pieces in place of magnesium. Both of these bikes produced 126 hp (94 kW) 101.78 rear horsepower, with a 13300 rpm redline. Top speed is estimated at 170 mph (273 km/h) @ 12800 rpm, 0–100 km/h estimated at 3.1 seconds, quarter mile 10.98 seconds @ 131 mph (211 km/h). The F4 750 uses a 49 mm Showa front fork and Sachs rear suspension. MSRP $18,895.
The F4 750 also comes in a 1+1 (Biposto) model, which has a pillion for a passenger.
F4 750 Senna
The F4 750 Senna was also released in 2002 along with the Evo 02 model 0-60 2.9 quarter mile 10.7 @ 135. Built purely to raise money for the Instituto Ayrton Senna, a charity founded by Ayrton Senna to aid the children and young people of Brazil, the Senna was a limited production run of 300 bikes like the Oro. The Senna shared the 136 hp (101 kW) engine of the Evo 02 but with a higher redline of13900 rpm, and top speed estimated at 175 mph (282 km/h) @ 12750 rpm . The Senna also had some suspension upgrades and some carbon fiber bodywork. MSRP $24,995.
F4 750 SPR and SR
The F4 750 SPR was released in 2004 and was intended to be the final evolution on the F4 750 platform. It had an improved 146 hp (109 kW) engine, (13,900 rpm redline, polished ports, HC pistons), matte grey race livery, some carbon fiber bodywork (front fender, chain guards, air ducts covers) and a Marzzochi 50 mm fork. The F4 750 SR was released after the SPR, and used the same frame an F4S (Showa fork, no carbon parts), but the same engine of SPR version. Both the SPR and SR were limited production runs of 300 bikes. top speed estimated at 180+ mph 13,900, 0-100 umknow-+=/ quarter mile 10.4 @ 139 mph. The SR was released in the traditional red/silver livery of MV with a color coordinated red front fender and a bronze Arrow exhaust system. It also has a white gauge face, different from the standard yellow, which displays Agostini's signature in red. It also has the signature silver star rims and SR plate placed on the steering head.
F4 AGO
Like the F4 750 and the Oro, the new F4 1000 product line began with a special edition F4 1000 called the F4 AGO in 2005. The F4 AGO came with a special graphics prominently displaying the number "1" in a yellow oval in reference to MV Agusta's racing heritage and driver Giacomo Agostini. Only 300 bikes were produced.
F4 1000 S
The first mass produced F4 1000, the F4 1000 S, was released in 2005 and came with a 166 horsepower (122 kW) engine 142 rear horsepower. The F4 1000 S comes equipped with a 50 mm Marzocchi front upside down fork and Sachs rear suspension. A 1+1 version adds a pillion for a passenger. Expect 0-60 in 2.7 seconds, the quarter mile in 9.95 seconds @ 144 mph, and a top speed estimated at 300 km/h (190 mph).
F4 Tamburini
The F4 Tamburini is a special edition of the F4 1000 S released in 2005. It was the first F4 to be equipped with the Torque Shift System (TSS), which varies the length of the intake trumpets with speed in order to provide optimum torque at low and high engine speeds. Engine output was a claimed 128 kilowatts (172 hp) and claimed top speed was 190.6 mph (306.7 km/h). It was sold for over US$ 42 thousand and only 300 were produced. The bike is named after its designer Massimo Tamburini.
F4 1000 R
The second mass produced F4 1000, the F4 1000 R, was released in 2006 and came with a 174 horsepower (128 kW) engine . The F4 1000 R also has upgraded Brembo Monobloc radial brakes, forged black Brembo wheels, a carbon-nitride coated Marzocchi upside down fork and an upgraded Sachs rear shock absorber (compression & rebound damping adjustable in high & low speed range). The F4 1000 R engine does not utilize the TSS system. A 1+1 (Biposto) version is available that adds a pillion for a passenger. In August 2006 an F4 1000 R was used to set a record for the fastest production class 1000 cc motorcycle of over 185.882 mph (299.148 km/h) at Bonneville Salt Flats.
F4 1000 Senna
The F4 1000 Senna is a special edition of the F4 1000 R released in 2006. It is similar to the 2002 F4 750 Senna in spirit, but has some changes to the paint scheme and an alcantara seat. This model comes with the 174 horsepower (128 kW) engine and has also the upgraded BremboMonobloc radial brakes, forged silver Brembo wheels, a 50 mm titanium-nitride coated Marzocchi upside down fork and a lightweight Sachs racing rear suspension (in high & low speed range adjustable rebound and compression damping). Only 300 were produced.
F4 Veltro
The F4 Veltro comes in two models, the F4 Veltro Strada (road) and F4 Veltro Pista (race). Ninety-nine examples of the Strada were produced, as well as 23 examples of the Pista. As is standard for a race modified motorcycle, the Pista is not equipped with headlights. The Veltro models engines feature the TSS system originally found on the F4 Tamburini. These are considered by many to be the most race-oriented F4's available.
The Veltro Strada is equipped with a full complement of carbon fiber (fairings, tail, airbox, mud guards, fenders, air ducts, heat shield) and magnesium frame plates.
In addition to the parts found on the Veltro Strada, the Veltro Pista is equipped with a lightened frame, oversized radiator, carbon fiber fuel tank, and a magnesium triple clamp and swingarm.

F4 R 312 name is a reference to the bikes claimed top speed of 312 km/h (194 mph) making it the fastest production bike at the time. In August 2007, the 312R set the new Land Speed Record at Bonneville Salt Flats in Utah for the fastest Production Motorcycle in the world, averaging 311.53 km/h, over the long course, which is 7 miles (11.3 km) long. The top speed achieved during the run was over 314 km/h, which was achieved at mile marker number 4. The speed record is determined by averaging the speed of the entire length of the course.
