Aprilia Tuono V4 2021 — Specifications

Imagine Aprilia decided, one fine morning, to teach good manners to a hardened criminal. That is roughly what this evolution of the 2021 Aprilia Tuono V4 represents: a machine whose DNA comes directly from the RSV4, from the racetrack, yet one that now agrees to share the road without destroying everything in its path. It was a bold wager. It has largely paid off, with a few nuances worth laying on the table.

The first contact strikes you with its stylistic coherence. The headlight unit echoes the RS 660, the silhouette borrows from the RSV4, and the whole forms a naked bike whose presence has nothing to envy from a KTM Super Duke R or a Ducati Streetfighter V4. At 185 kg dry and 209 kg fully fuelled, the 2021 Tuono V4 1100 Factory is no featherweight, but it proves surprisingly nimble for a machine that impresses on sheer size alone. The 825 mm seat height remains accessible for average-sized riders, and the narrowed tank noticeably improves grip under braking — a detail that matters when talking about a machine capable of topping 250 km/h.

Beneath the bodywork, the 1077 cc V4 produces 175 horsepower at 11,000 rpm and 121 Nm of torque at 9,000 rpm. Those figures would already be enough to make an experienced rider's knees tremble, but what sets this generation's engine apart is its internal refinement. Lightened valves gain 300 rpm of usable range, the Magneti-Marelli management unit has quadrupled in processing power, and the whole package complies with the Euro5 standard without conceding a single horsepower. That is rare. On a Kawasaki Z1000 or a BMW S 1000 R, the compromises are more perceptible. Here, Aprilia has played it tight.

The electronics deserve close attention, because the APRC package on the Aprilia Tuono V4 Factory is not a marketing argument — it is a tool. ATC traction control across 8 levels, AWC wheelie management across 5 positions, AEB engine braking across 3 settings, cornering ABS, anti-stoppie, bidirectional quickshifter, launch control, cruise control. Six riding modes organised into two families — road and track — three of which are fully customisable. An inertial measurement unit governs the entire system. On a track test of the Aprilia Tuono V4, this sophistication genuinely changes the game. On the road, it allows an intermediate rider to access sensations they could not have managed alone.

The aluminium perimeter frame inherited from the RSV4 does the rest. The 43 mm inverted Sachs fork and the remote-reservoir rear shock are fully adjustable. The swingarm, redesigned with just three welded pieces compared to seven previously, boasts a 48% increase in lateral rigidity. Brembo radial four-piston calipers bite 330 mm discs up front, with stopping power that belongs at the very top of the category. The TFT screen grows from 4.3 to 5 inches, the lighting pivots through corners, and the turn signals activate during emergency braking.

What surprises about the 2021 Aprilia Tuono V4 is precisely this willingness to no longer be purely a machine for extreme sensations. The standard version accommodates a passenger in genuine comfort, with lowered footpegs and a properly sized grab rail. That is a first in the Tuono family, and it shifts the profile of the intended buyer. The Aprilia Tuono V4 price is set at €16,099, placing it in direct competition with the Streetfighter V4 and the Super Duke R. Within that triangle, each machine has its own logic. The Aprilia is the most electronically sophisticated, the most directly derived from competition, and probably the most versatile of the three. For an experienced rider seeking a machine that performs equally well on a mountain pass and at a track day, it is the most coherent option. Not the most docile on the first kilometre. But the most complete over time.
