Aprilia Tuono 660 heading towards showrooms
Aprilia’s much anticipated Tuono 660 is nearing reality and the best bit is that it’s barely changed from the prototype.
Although Aprilia’s 100hp RS660 twin-cylinder sports bike is the headline-maker of the range its part-faired Tuono 660 sibling could well be the bigger seller once both bikes reach dealers. That day is getting closer, with the firm’s final design for the Tuono 660 appearing in newly published patent documents.

Aprilia never made any bones about the fact the smaller Tuono, which was shown as a concept bike last November, has always been destined for production. It’s scheduled to go on sale in 2021, a few months after the RS660. Inevitably there are tweaks to be made between the ‘concept’ stage and the production version, but the new patent shows they’re minimal.
You’ll have to look closely to spot the slightly more extensive bellypan, needed to disguise the cleverly packaged exhaust system that manages to squeeze all the mandated Euro5 emissions and noise reductions kit into the space under the engine.
The pan is deeper and more elaborately-shaped than the concept version’s, and features a fractionally larger pair of winglets near the front along with an extra air outlet vent.
Look closer still and you’ll spot the exhaust header that now bulges before disappearing behind the bellypan; an indicator that there’s an additional catalytic converter in this section of the pipe.
That positioning puts the cat as close as possible to the exhaust port so it heats up faster after a cold start. That’s a vital part of the latest Euro emissions rules, since bikes put out the vast majority of emissions in the few seconds after first starting.
Elsewhere, the styling is almost unchanged. The patent images lack the lever guards on the bar ends, and the Brembo brakes feature a rectangular reservoir rather than cylindrical, but these changes aren’t necessarily representative of the production bike’s design as neither component is likely to be considered a styling element as covered by the design patent.
Under Aprilia’s plan we’re expecting the definitive version of the Tuono 660 to appear this autumn at around the same time as the RS660 reaches production. Tuono 660 sales will follow in 2021, with a Tuareg 660 model joining the range after that.
