Aprilia Tuono 660 2025 — Specifications

When Noale presented the Aprilia Tuono 660 concept at the end of 2019, few imagined the production version would be so accomplished. Yet, the recipe was there for all to see: take the RS 660’s inline twin, remove five horsepower to bring it to 95 hp at 10,500 rpm, fit a handlebar instead of clip-ons, and unleash the beast on the roads. Simple on paper. Formidable in practice.

What immediately strikes you is the visual density of the machine. We expected a stripped-down roadster, and we discover a streetfighter that fully embraces its kinship with the RS. The triple headlights give it an aggressive look that few competitors of this size can claim. The integrated winglets aren’t just for show; they contribute to aerodynamic management, a detail that recalls that the Aprilia Tuono 660 descends from a lineage where the track is never very far away. The passenger, on the other hand, will appreciate it moderately: the rear section clearly prioritizes style over comfort, without ambiguity.

The engine is the central subject of the Aprilia Tuono 660 technical specifications, and it deserves attention. This 659 cc twin, with a 270-degree crankshaft, develops 67 Nm of torque at 8,500 rpm, exactly the same as the RS 660. Aprilia compensated for the slight loss of power by shortening the transmission ratios to densify the acceleration. As a result, where an MT-07 or a Z 650 of comparable displacement peak around 73 hp, the Noale twin displays 95 hp with a compression ratio of 13.5:1, a bore of 81 mm and a stroke of 63.9 mm. It’s an architecture that plays in another category, and you can feel it. The bridled Aprilia Tuono 660 is perfectly suited to the A2 license, without requiring complex modifications, which considerably expands its audience.

The price positioning at 10,599 euros is the point that deserves debate. At this price, you’re no longer playing in the yard of the SV 650 or the 660 Trident; you’re directly tackling the Street Triple and other 800 to 900 cc roadsters. The Tuono’s engine doesn’t reach the brute power of these higher displacements, and the torque remains below what the segment references produce. Aprilia is betting on something else: the chassis. The perimeter aluminum frame borrows the same base as the RS, with a wet weight of 183 kg, suspensions recalibrated for road use and a steering geometry adapted to the raised riding position. If the Aprilia Tuono 660 test confirms what the specs suggest, the cycle part should be the real persuasive force against the English competitors.

The onboard electronics are generous for this segment: ride-by-wire, ABS, multi-level traction control, anti-wheelie, cruise control and five riding modes, including two dedicated to the track. A color TFT screen complements equipment that few machines at this price can match. Options like the quickshifter, IMU with cornering ABS or adaptive headlights will require opening the Aprilia Tuono 660 accessories catalog. It’s not a fault in itself, but a commercial strategy that leaves the base version accessible, with a clear margin for personalization for those who want to push the machine towards the Factory version. The announced top speed of 220 km/h clearly positions the machine between two worlds, fast enough to impress, not enough to claim the title of segment king. It is precisely there that lies its charm and its limit.
