The Aprilia RS 660 sits low and narrow, the tank pressing lightly against your ribs as you clip your boots onto the pegs and feel the soft click of the quickshifter under your left toe. The TFT dash wakes up in clean colors, and the parallel twin coughs to life with a tidy, sharp bark. It feels like a sportbike that wants to play but will not bully you on the way to work.

Where the RS 660 stands

The Aprilia RS 660 is Aprilia’s middleweight faired sportbike, built around a 659 cc parallel-twin engine that delivers about 100 hp, depending on market tuning. It slots between the brand’s smaller 125 cc machines and the V4 superbikes, aiming at riders who want a lighter, more practical road package.

Chief technical officer Romano Albesiano has repeatedly described the RS 660 concept as “performance you can use every day”, with chassis geometry tuned for fast road riding rather than only track work. The bike’s aluminum frame, relatively relaxed clip-on position and wide, flat seat all reflect that brief, and you feel it as soon as you tip it into a city roundabout.

Engine, electronics, and feel

The 659 cc twin in the Aprilia RS 660 is derived from the brand’s larger V4 architecture, essentially using half the block with a crank and head designed for torque in the mid-range. It revs freely, but the important sensation is the clean drive from 4,000 rpm upward, where the bike pulls out of tight corners without needing race-level gear juggling.

Aprilia fits a full ride-by-wire system with multiple riding modes, traction control, engine braking adjustment, and an up-down quickshifter on most RS 660 trims. These systems let you soften the bike for wet commutes or sharpen it for canyon runs, and the transitions between modes feel smooth and self-assured rather than abrupt.

Comfort and daily usability

On the move, the Aprilia RS 660 feels light in the hands. The steering responds quickly but not nervously, and the suspension manages rough urban asphalt without punishing the rider. You notice how the front end tracks through broken tarmac, the fork filtering chatter rather than sending every edge straight to your palms.

The seat padding is firm but not harsh, allowing a couple of hours of riding before you start shifting your weight. Combined with a relatively modest seat height, the RS 660 is approachable for many riders who might be intimidated by taller adventure bikes or pure track machines.

Design, finish, and equipment

Visually, the Aprilia RS 660 carries a slim nose with split LED headlights and winglet-like side panels that tie it to the brand’s racing identity. Paint schemes often mix bold color blocks with clean logos, giving the bike a self-assured look without turning it into a rolling billboard.

Build quality feels consistent with the mid to upper price bracket: body panels fit tightly, switchgear clicks positively, and the TFT display presents information clearly in sunlight. Some owners report minor irritations like fiddly mirror adjustments or modest under-seat storage, but these are typical of faired sportbikes rather than specific flaws.

Pricing and market position

Depending on market and trim, the Aprilia RS 660 usually sits near the upper end of the middleweight segment on price, reflecting its electronics package and brand positioning. In Europe, list prices tend to cluster well above entry-level twins, closer to premium Japanese and European rivals.

This pricing strategy positions the RS 660 as a step-up bike for riders who have moved beyond basic commuters and want more character without committing to litre-bike insurance and running costs. It also creates space below Aprilia’s Tuono 660 and larger RSV4 line, keeping the portfolio ladder tidy.

Strengths and weaknesses

Among its strengths, the Aprilia RS 660 offers a convincing balance of power, weight, and technology in a package that still feels manageable. The electronics suite and engine character support both spirited weekend use and calmer weekday riding, which is exactly what many real-world riders look for.

On the downside, dealer coverage is thinner than some Japanese brands in several markets, which can mean longer trips for service or test rides. There are also reports of occasional software quirks on early models, though later updates appear to have addressed most of these issues.

Stock and broader context

Piaggio & C. SpA uses the Aprilia RS 660 as part of its strategy to hold a meaningful space in the mid-size motorcycle market alongside its scooters and heritage brands. Overall, this helps keep attention on the broader group, even if the core financial story still revolves around volumes from Vespa, Piaggio scooters, and Moto Guzzi. The company’s shares trade primarily on Borsa Italiana in Milan under the symbol PIA, giving investors a direct line into the mix of sportbikes, commuters, and light commercial vehicles that define the group.
