'TSS' is able to lower peak torque from the 10000 rpm to 9000 rpm while maintaining maximum power. The 'TSS' system has two positions, it is not able to vary the height of the intake ducts continuously. The 'TSS' system is designed to increase torque in the low to midrange, while still allowing for maximum horsepower at the top of the rev range (usually two mutually exclusive properties of an engine).

The F4 Tamburini, F4 Veltro, and F4 CC models are equipped with variable length intake ducts known as the 'TSS' system. The F4 engine is unique in the sense that it is the only recently produced radial-valved motorcycle engine. MV (Cagiva at the time) quickly deviated from the Ferrari design, but they kept one important feature, the radial valves. Early in the design process Ferrari engineers assisted in the development of the engine. The engine was derived from the 1990–1992 Ferrari Formula One engine. The F4 engine is a liquid cooled inline four cylinder four-stroke set across the frame with two overhead camshafts ( DOHC), 16 'radial' valves, electronic multipoint fuel injection, and induction discharge electronic ignition having engine displacements of 749.5 cc (45.74 cu in), 998 cc (60.9 cu in), and 1,078 cc (65.8 cu in). The F4 engine is also one of the few production superbikes to have a hemi-spherical cylinder head chamber design with 4 valves per cylinder. The F4 has a single-sided swingarm, large diameter (49 or 50 mm (1.9 or 2.0 in)) front forks and traditional MV Agusta red and silver livery.

The F4 was created by motorcycle designer Massimo Tamburini at CRC (Cagiva Research Center), following his work on the Ducati 916. It was the motorcycle that launched the resurrection of the brand in 1998. The MV Agusta F4 is an inline four-cylinder sport bike made by MV Agusta from 1999 until 2018.
