2025 Aprilia Tuono 660 Factory First Look

For 2025 Aprilia has slimmed down its Tuono 660 range and moved it upmarket, ditching the base model and raising the specification of the higher-end Tuono 660 Factory with more power, better suspension, and improved electronics.

Like the larger Tuono V4, the 2025 Tuono 660 Factory gets a mildly revised appearance, ditching the bellypan of its predecessor to emphasize the naked style and save a bit of weight. But the biggest change of all is the suspension, which sees the previous model’s Kayaba parts thrown out in favor of Öhlins bits. The fork is a 43mm NIX 30 unit, 2mm fatter than the 41mm Kayaba fork it replaces and fully adjustable for compression and rebound damping as well as spring preload. At the back, an Öhlins STX 46 shock is introduced, again with fully adjustable damping and preload.

While the loss of the bellypan hasn’t reduced the bike’s overall weight—it’s still measured at the same 399 pounds as the previous generation—the power-to-weight ratio gets a hike thanks to engine tweaks that add 5 hp for a total of 105 hp. The essence of the motor is unchanged, with the same 659cc capacity and RSV4-derived construction, but the 2025 model gets 52mm throttle bodies to replace the previous 48mm versions to release a handful of extra horses. The exhaust is also modified, with a more conventional shape to the headers and a neater design to the collector, which is now exposed thanks to the elimination of the lower bodywork.

The main frame is unchanged, a cast aluminum half-chassis using the engine as a structural part but gets finished in black for the 2025 bike—a subtle change but one that combines well with the black bodywork to give a more cohesive flow from the nose fairing to the tank and seat unit. Black paint also covers the swingarm and wheels.

Aprilia has also focused on the bike’s electronics. On board you’ll find a new 5-inch TFT dash, larger than the previous version and, via backlit bar controls, giving control over the bike’s impressive array of rider assists. Those include cornering ABS with multiple maps and a six-axis IMU that allows lean-sensitive traction control. There’s wheelie control, too, and cruise control, as well as an up/down quickshifter and switchable maps for both the engine’s power output and its engine-braking behavior. A new addition to the rider-assist package for 2025 is launch control to optimize standing starts.
