The Sport Bike That Is More Fun At 70 MPH Than Most Superbikes
The fastest motorcycle in a straight line is not necessarily the one that puts the biggest grin on your face. Some machines are built to chase lap times, and they do that brilliantly. But in real-world conditions, where traffic and corners arrive faster than expected, the most enjoyable bike is often the one that feels perfectly matched to the moment. True motorcycle euphoria comes from balancing accessible power and agility with the freedom to explore a bike’s limits without needing a racetrack to justify itself. This Italian sport bike promises exactly that.
Why Big Superbikes Often Feel Like Too Much On The Road
Liter-class superbikes are engineering marvels, but their extraordinary performance can be difficult to enjoy outside a racetrack. With power outputs often exceeding 200 horsepower, they can reach illegal speeds almost instantaneously, leaving riders with little opportunity to explore their capabilities responsibly. In urban traffic environments, high-revving engines generate considerable heat, while aggressive riding positions and firm suspension setups can also make everyday commutes tiring. The result is a motorcycle that may be technically faster but often leaves less room for the rider to feel truly involved.
Real-World Fun Comes From Dynamic Balance, Not Brute Force
The most rewarding rides rarely come down to raw power; instead, they are defined by dynamic balance. A motorcycle does not need overwhelming horsepower to feel exciting; it needs an agile chassis and a predictable engine that lets riders carry momentum through corners, flick the machine effortlessly between turns, and roll onto the throttle with confidence. One Italian middleweight sport bike gets this formula remarkably right. At 70 MPH, it can deliver a far more engaging experience than a much more powerful superbike because you are exploring its capabilities rather than merely managing them.
The Aprilia RS 660 Delivers Superbike Excitement In A Usable Package
Starting MSRP: $11,849
The Italian motorcycle in context is the Aprilia RS 660. Unveiled in 2020 as Aprilia’s fresh approach to sport bike performance, it bridged the gap between entry-level machines and flagship superbikes. The RS 660 was designed to prove that a sport bike does not need a liter-class engine to feel special. It blended Aprilia’s racing pedigree and was developed to deliver an engaging experience on public roads as well as on the track.
For 2026, the standard Aprilia RS 660 starts at $11,849 before destination charges and taxes, while the track-focused RS 660 Factory is priced at $14,149. Its racing credentials are more than just marketing language, with Aprilia positioning the RS 660 as a benchmark for lightweight, high-performance motorcycles. MotoGP-inspired winglets, a sharp all-LED front end, and sculpted bodywork give it an unmistakable road presence, but its real appeal lies in how accessible it feels on the road.
A 659cc Parallel-Twin That Delivers Performance Where Riders Actually Use It
Powering the Aprilia RS 660 is a 659cc, liquid-cooled, parallel-twin engine with a 270-degree crankshaft layout, derived from the front bank of the legendary RSV4’s mill. It produces 105 horsepower at 10,400 RPM and 51.6 pound-feet of torque at 8,400 RPM, paired with a six-speed manual gearbox. These are serious numbers for a middleweight sport bike under 700cc, but what matters more is how the engine delivers them. There’s enough low- and mid-range pull for confident overtakes and brisk roll-on acceleration, while still encouraging riders to work through the gears when the road opens up. Ride-by-wire, slipper clutch, and quickshifter contribute to a more controlled riding experience.
The engine also serves as a structural component, working with the twin-spar aluminum frame to create a compact, rigid, lightweight chassis setup. This integration helps the RS 660 feel planted at high speeds. For riders seeking a sport bike for weekday commutes and spirited weekend rides, the RS 660’s powertrain strikes a remarkably effective balance.
Sporty Ergonomics And Lightweight Chassis Make Every Corner More Engaging
The Aprilia RS 660’s greatest advantage over a superbike is its sense of scale. With a curb weight of just 403 pounds, it is almost 40 pounds lighter than a regular superbike. So it should feel nimble through tight corners and manageable at low speeds. Additionally, the ergonomics strike a similarly intelligent balance between track readiness and everyday comfort. Its seat-handlebar-footpeg relationship keeps the rider engaged during spirited cornering while remaining comfortable on longer rides. Meanwhile, suspension consists of a 41mm KYB inverted front fork and a rear monoshock, both adjustable for preload and rebound damping. Braking hardware is equally serious. It uses dual 320mm front discs with radial-mounted Brembo calipers, paired with a 220mm rear disc.
Premium Electronics Bring Flagship Features To A Middleweight
Unlike some middleweight motorcycles that skimp on rider aids, the RS 660 features the advanced APRC (Aprilia Performance Ride Control) suite, directly inherited from flagship superbikes. Driven by a six-axis IMU, the electronics package includes multiple engine maps, cornering ABS, traction control, wheelie control, engine brake control, launch control, cruise control, and a bi-directional quickshifter. The RS 660 also gets five riding modes divided between Road (Commute, Dynamic, Individual) and Race (Challenge, Time Attack) categories. A five-inch color TFT display and backlit controls make the technology easy to navigate.
The Aprilia RS 660 Makes More Sense Than A Superbike For Most Riders
For most riders, the Aprilia RS 660 makes a stronger case than a superbike because it delivers the essential ingredients of sport riding in a package that remains usable every day. It is fast enough to feel special, light enough to inspire confidence through corners, and comfortable enough for real-world rides. Starting at $11,849, it also undercuts many flagship performance motorcycles while offering technology that would have been unthinkable in this class until recently.
Against its direct middleweight rivals, its strengths become even clearer. The Triumph Daytona 660 offers a distinctive three-cylinder engine producing around 95 horsepower and a lower starting MSRP of $9,395, making it an appealing value-oriented alternative. The Yamaha YZF-R7 and Honda CBR650R are capable, more road-biased middleweights, but neither matches the Aprilia’s combination of performance, electronics, and race-bred chassis hardware. The RS 660 may not be the fastest on paper, but its balance of performance, agility, and everyday usability makes it one of the most compelling choices in the class.
