We put the Aprilia RS 660 Factory through its paces: real 240 km/h top speed testing, Öhlins suspension performance, ergonomics for tall riders, pros, cons, and pricing.

Priced at €14,100, equipped with race-spec Öhlins suspension, and sporting MotoGP-derived aerodynamic wings. But how does Noale's middleweight sportbike actually perform when pushed to its absolute limits? Here is what our real-world test revealed.
The Speed Test: Beyond the 230 km/h Threshold
The question haunting every sportbike enthusiast is always the same: can a 659 cc twin-cylinder engine truly challenge traditional middleweight sports bikes?
The answer lies in Aprilia's extensive aerodynamic development. The new winglets integrated into the fairings aren't just for show at the local coffee shop; they actively reduce drag while providing high-speed stability:
At an actual 230 km/h (143 mph): The RS 660 Factory reaches this speed with surprising fluidity, accompanied by lightning-fast gear changes from the electronic quickshifter.
At a true top speed of 240 km/h (149 mph): The GPS-verified top speed (officially claimed by Aprilia) requires a long straightaway and a rider completely tucked onto the fuel tank.
While speedometer readings hover close to 250 km/h, the most impressive takeaway isn't the number itself—it's the complete absence of handlebar weave or front-end float, thanks to front aerodynamic downforce and the 43 mm Öhlins NIX30 fork.
Magic in the Twisties: Mind the Rider Ergonomics
The true strength of the RS 660 Factory lies in its aluminum chassis and a wet weight of just 183 kg (403 lbs). During quick direction changes, the bike feels like a much smaller displacement machine due to its agile and precise nature.
However, there is a crucial ergonomic factor to evaluate before buying:
Riders between 170 and 175 cm (5'7" – 5'9"): The setup is spot-on. The clip-on handlebars offer just the right amount of weight on the front end to feel feedback without killing your wrists after 30 minutes.
Riders over 180 cm (5'11"): The compact proportions become obvious. Knee bend angles become pronounced, and the stock windscreen offers limited wind protection during high-speed highway transfers.
3 Key Strengths (and 1 Limit to Keep in Mind)
1. The 105 HP Euro 5+ Engine Feels Punchier
The upgrade to new 52 mm throttle bodies adds 5 extra horsepower and delivers even cleaner throttle response, completely eliminating low-RPM snatchiness.
2. Öhlins Suspension Delivers a True Quality Leap
The €14,100 price tag is instantly forgiven at the first hard braking point: the supportive front fork and STX 46 rear shock allow you to trail-brake deep into corners with rock-solid confidence.
3. Fuel Economy That Won't Scare You Off
At a brisk pace on winding roads, you can easily achieve 18 km/L (42.3 mpg), a figure that climbs above 22 km/L (51.7 mpg) during relaxed touring.
The Single Real Limit: Top-End Pull on Endless Straights
When tested on fast, open circuits against four-cylinder engines or 1,000 cc superbikes, the physics of a middleweight displacement resurface and the RS 660 has to yield ground. Its ideal terrain remains technical twisty tracks and mountain passes.
In Summary: Road Test Report Card
Öhlins Suspension (Score: 9.5/10): Professional-grade and track-ready out of the box, virtually eliminating pitch and load transfers.
Electronics & APRC Suite (Score: 9/10): Best-in-class package featuring Cornering ABS and fully customizable engine maps.
105 HP Engine (Score: 8.5/10): Extremely punchy in the mid-range with exceptionally smooth power delivery.
Long-Distance Comfort (Score: 7/10): Sporty ergonomics; excellent for the supersport category, but tiring on long highway stints.
