2025 · Naked Bike · A variant of the Tuono 660
Differences between the standard Tuono 660 and the Factory
Razor-Light Twin With Bite
Aprilia built the Tuono 660 Factory around a 659 cc parallel twin with a 270-degree crank, and that firing order is the whole personality of the bike: 103 hp, 49 lb-ft, and a pulse that never irons itself flat. An aluminum twin spar frame carries all of it at 399 lb wet, and that number shapes everything the bike does. On top sits the full APRC package running off a six-axis IMU, with cornering ABS, traction control, wheelie control and launch control. The bodywork runs without a bellypan, so the frame and the engine cases sit in plain view where they belong on a naked bike.
Feel comes first here and everything else falls in behind it. Fully adjustable suspension at both ends, cruise control, a TFT dash and LED lighting make it usable Monday through Friday, then it becomes the reason you set an alarm on Sunday. It suits an experienced rider who wants front-end feedback and Italian sporting intent more than displacement or touring hardware. The caveats are honest ones: no luggage system, no center stand, no heated grips, no USB port, a seat at 32.3 in (820 mm), and smartphone connectivity, navigation and tire pressure monitoring that all cost extra.

Most of what follows arrived sideways: paddock conversations, owner talk in parking lots, club nights, and the steady stream of mail and messages riders send me after they buy something. On this bike the chatter lines up cleanly. The praise clusters in two places, and the complaints narrow down to one.
The rider aids carry most of the conversation. Owners consistently describe a package that feels lifted from a much bigger machine, and what they come back to is how usable it is: the ride-by-wire throttle and the mode selection let the same bike handle a dull commute in the morning and a good road in the evening. Underneath that, riders describe a chassis that stays light and precise and flatters newer riders as readily as quick ones, with the Factory's fully adjustable Öhlins suspension and Brembo Stylema brakes holding up the hardware end.
One complaint recurs, and it is always the same one. Riders find the handlebar switches and buttons cheap under the thumb, short on the tactile feel they expect at this price. It comes up from owners who otherwise speak well of the bike.
Loose engine case screws
Engine vibration can cause screws on the engine case covers to loosen over time, requiring periodic retightening or threadlocker application.
Minor oil leaks from hose clamps
Some owners have reported small oil leaks from the oil cooler or hose connections, often fixed by replacing spring clamps with screw clamps.
Rear brake squeak at low speed
A squeaking noise from the rear brake is common during slow-speed operation; bedding in the pads properly sometimes resolves it.
Where this Aprilia Tuono 660 pulls ahead of — or falls behind — its rivals on the numbers, and the typical bike in its class on character.

Forget spec-sheet bragging. Here's who the Tuono 660 is actually built for.
Ridge road Sundays with a city commute in between is exactly this bike's week. Light in traffic, worth looking at when you park it, and quick enough on Skyline that nobody waits on you.
Made for Bay Area Ridge Roads · San Francisco / Bay Area · Skyline Boulevard / Alice's Restaurant
You have the skill to use this one. 103 hp in a 399 lb chassis means your canyon pace comes from corner speed and feel, not from power you can only hold for a second.
Made for Angeles Crest Highway · Coronado Trail / US 191 · Highway 1 / Big Sur
Three hundred corners in an afternoon is where this chassis makes sense. Light steering and real front-end feedback let you work on your lines instead of wrestling the bike.
Made for Back of the Dragon · Blue Ridge Parkway · Cherohala Skyway
If you're cross-shopping the older generation, here's what changed.

Compare to the previous model →If this one isn't quite the fit, these are the bikes worth riding back-to-back against it.
Any price note compares both bikes at the same age — the youngest age both have on the used market — against this Aprilia Tuono 660. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
