The Aprilia Tuono 660 is based on the Aprilia RS 660 middleweight sport bike, with a pair of handlebars, some plastic shaved off, and geometry tweaked to make the RS 660's racing capability and technological complexity even more suitable to the street.
TWO UNIVERSES COLLISION AS STRONG AS THUNDER, LIGHT AS A CLOUD The TUONO 660 is a motorcycle that combines the renowned Tuona V4 1100 with the modern technology of the RS 660 to produce a motorcycle that will change the way you see the world.
For several years, the middleweight naked sport bike class has maintained a high level of excitement. Street-ready motorcycles with a sporting pedigree have aided in keeping the motorcycle industry afloat.
A design brief like that has already grabbed your interest if you have even a smidgeon of an interest in sport riding. Let me now hold your attention: the 659cc parallel-twin engine is a true treasure, with a 270-degree firing order and a raspy exhaust noise that will make Tuono V4 owners do a double-take at bike night.
The Tuono 660's superb 403-pound wet weight, which offers an impressive power-to-weight ratio, is the final blow to the competition. It produces 100 horsepower at 11,500 rpm and 50 lb-ft of torque at 10,500 rpm (all figures claimed)
Nearly 80% of the Tuono's torque is available at just 4,000 rpm, making it ideal for weaving through traffic. It pulls hard and fast until roughly 9,500 rpm, when it settles down beautifully.
The Tuono's powertrain, crucially, does not overwhelm. As you dive into and out of corners, it stimulates, inspires, and motivates you, but it's a ride that intermediate riders can handle and expert riders can completely utilize. Although the 660 twin has some design elements with Aprilia's V4s, such as different length intake funnels, electronically driven 48mm throttle bodies, a 13.5:1 compression ratio, an 81mm bore, and a basic cylinder head design, it is a distinct beast and far more approachable.
