MV Agusta 921 S: the prototype between past and future

MV Agusta 921 S is the name of the concept that re-elaborates the style of the past by blending it with the technology of the future. This is not a simple exercise in style, it is a concrete starting point for a bike that will be developed and presented in the coming years.

The 921 S project was born from the intuitions of Brian Gillen and Stephen Zache, who look to the 1973 MV Agusta 750S with the aim of making it the reference point for a futuristic model, which remains anchored in the history of the brand. The 921 S prototype is not a simple makeover of the 750S but a homage.


Lines and volumes resume the proportions of the past while the body of the concept is particularly slender to accommodate the new four-cylinder in-line engine. The technical equipment and mechanics are first in class: from the chassis with the oversized swingarm to the rims, made with a combination of carbon fiber cover, spokes and forged rim, nothing is left to chance. Very eye-catching, and above all beautiful to look at, are the four tailpipes positioned under the engine. The aluminum front brake cover, on the other hand, is a solution designed to bring air to the calipers and cool them faster. The frame follows the famous layout of the new generation MV Agusta, with the trellis of welded steel tubes and the side plates in aluminum alloy. The circular instrumentation is also completely new, as in the past, but the screen is touch and rests on the tank. The handlebar, on the other hand, is inspired by time trial cycling competitions: the central area with an aerodynamic profile, made of a differentiated section in forged aluminum, is linked to two short half-handlebars of racing inspiration. In a few seconds it is also possible to switch from the single-seater saddle, covered in Alcantara, to a two-seater saddle while maintaining great stylistic consistency.

The engine

The engine, as mentioned, is a four-cylinder in-line with 115.5 Hp at 7000 rpm and 116.5 Nm of maximum torque. Several technical solutions have optimized the performance of this engine: from the revised intake ducts to the more efficient liquid cooling circuit, up to the unprecedented profiles of the camshafts, designed to offer a particularly progressive response to the gas, for the benefit of ease. of use. A countershaft reduces second order vibrations. Connecting rods and pistons are specific to this four-cylinder unit, as are the entire intake assembly (throttle bodies and injectors).
