Sports bikes are fun because they are fast. There is nothing faster on asphalt than a combination of a sports bike and a race track. In the real world, however, there are speed limits, traffic lights and drivers who cannot see motorcycles. Maybe you also want to enjoy the landscape in 4D during a trip and choose to ride a motorcycle. For all these use cases outside a race track, sports bikes are terrible. They are tight, do not steer well at low speeds, have a fuel tank that is ridiculously small and is generally a pain in the neck (and back).
There is a new generation of sports bikes that have now launched on the market that take into account the fact that sports bikes are also used on the street. They are not as aggressive as a traditional bike, but will still succeed in offering a lot of fun on the strange track day. One of the best in that is the bike we are talking about here in detail. Let’s tell you why this sports bike delivers both raw performance and daily usability.
To give you the most up -to -date and accurate information, the data used to collect this article from Aprilia Motorcycles and other authoritative sources come.
The Aprilia RS 660 is the sports bike that delivers both rough performance and daily usability
Price: $ 11,749
Aprilia is a well -known name in the racing world of the road, which has long been a participant in the highest echelons of motorcycle races. The sports bikes are unparalleled – there is the 220 hp RSV4 on one side and the beautiful RS 457 on the other. Both products offer things that are unique to the class. The RS 660 is located in the middle of the two, and it also continues the tradition of the Aprilia sports bike. It has speed in kicking, but Aprilia has put some effort into making it somewhat usable every day, despite its focus on being fast. That is why the RS660 is the sports bike that delivers both raw performance and daily usability.
Why we chose the Aprilia RS 660
Two-cylinder engine, four-cylinder power
APRC Electronics Suite
Lightweight
Looks fantastic
Aprilia RS 660 Engine: A Work of Art
Output: 105 hp
It is said that the RS 660 engine is being built from half the RSV4 engine. Based on the specific output, we tend to believe it. This 659 cc parallel twin engine with a 270-degree crank generates 105 hp. For context, the Ninja 650, another middleweight sports bike (albeit a focused on usability), 67 hp of 649 cc. Even if you choose the inline four-cylinder middle weights, such as the CBR650R E-link, it makes 94 horses. The only middle weights that surpassed the capacity of the RS660 are the Old-school no-compromise Supersport 600S with their screaming inline four engines, or middle weights with considerably more displacement.

Aprilia Tames This output with a by-wire throttle and a six-axle Imu linked to his famous APRC Electronics Suite. So you get the most extensive function set in the segment in this regard.

Aprilia RS 660 Chassis: Beauty and Brains
Aluminum frame, adjustable bewing
This is perhaps the most advanced chassis in the middleweight segment, and not just because of the electronics. The RS 660 uses an aluminum Twin-Spar frame in the beginning and adds an aluminum swingern bridge. This is a good large bicycle-shed bridge, none of your lazy cash register section, and it has a movable pivot point that is on the motorcycle carter, not the frame, to save weight. If you bring this to the race track, that adjustable pivot point will be essential to fight squat and extension and to improve the trust of the rider.

KYB offers the suspension that is adjustable for input tax and rebound at both ends. Traveling floats around five-inch mark. The brakes are items from Topplank from Brembo: On the front there are double 320 mm floating slices with radially mounted Monobloc brake claws. At the back there is a smaller disk, but the caliper is a fixed, not a floating, for better feeling and feedback. Metal braided hoses and a Brembo -radial main cylinder round the set of brake components. Here too, the APRC -suite functions such as curves offers ABS with three different cards and rear wheel lift limit.
Aprilia RS 660 Functions
Great function set for daily use or a track day
The party trick of Aprilia RS 660 is the APRC -suite. There is only one other middleweight sports bike that offers things such as launch control, but the level of adjustment, such as the ABS intervention and motor cards, is unique for the Aprilia. There is also the movable Pivot point -it might not be useful on home -working traffic, but on the circuit it will come a world of difference from a corner.
Aprilia RS660 Remarkable functions
5-inch TFT color display
Bluetooth -Connectivity with navigation
MotoGP style wings
Six -axis imu
Cruise control
APRC Electronics Suite
Launch check
3-level bends ABS
Aluminum Twin Spar Frame
Aluminum swingern bridge with movable pivot point
The usual characteristics are also present: a five-inch TFT color display gives the rider access to the many parameters of the APRC suite. Moreover, the Bluetooth has connectivity and navigation. In combination with the cruise control, the RS 660 could also work as a tour bike for short trips. Oh, and we did not mention the MotoGP style of wings that have debuted on the RS 660 of 2025. This is important because Aprilia has been one of the leaders in aerodynamics in MotoGP.
It is confronted with competition from people like Yamaha, Ducati, CFMoto and Triumph
A lot can be taken out here. The RS 660 is located in the middle of the middleweight Sportbike segment. The cheaper are usually more practical, such as the Kawasaki Ninja 650 ($ 7,399) that we have mentioned earlier. Another practical option is the Honda CBR650R e-link ($ 9,899), but it is not what one would call sporty. There are also the Supersport 600 cc inline fours, of whom the King is the Kawasaki Ninja ZX-6R ABS ($ 12,399), but it is not practically something that it knows about. The Yamaha YZF-R7 ($ 9.199) is just like the Aprilia, but has fallen en masse on both strength and electronics, and therefore a lower price.
Aprilia RS660 versus Rivals
Aprilia RS 660 | Yamaha YZF-R9 | Duck Panigent V2 | CFMoto 675SS | Triumph Daytona 660 | |
Price | $ 11,749 | $ 12,499 | $ 12,370 | $ 7,999 | $ 9,195 |
Engine | 270-degree parallel twins | CP3 Crossplane Inline Three | 90-degree V-twin | Inline Three cylinder | Inline Three cylinder |
Displacement | 659 CC | 889 CC | 890 cc | 675 cc | 660 cc |
Current | 105 hp @ 10,400 rpm | 117.5 hp @ 10,000 rpm | 120 hp @ 10,750 rpm | 95 hp @ 11,000 rpm | 95 hp @ 11.250 rpm |
Couple | 51.6 LB-FT @ 8,400 rpm | 68.6 LB-FT @ 7,000 rpm | 69 LB-FT @ 8,250 rpm | 51.6 LB-FT @ 8,250 rpm | 50.9 LB-FT @ 8,250 rpm |
Pavement weight | 403 pounds (wet) | 430 pounds (wet) | 395 pounds (wet) | 429 pounds (wet) | 443 pounds (wet) |
That brings us to the true contenders. There is some tough competition here. At the bottom of the list is the Suzuki GSX-8R. It has decent execution, but to be honest it is a faster Ninja 650. Then there is the Triumph Daytona 660, which looks exactly like the Aprilia, but with a screaming three -cylinder engine. If you want more sportiness, there is the CFMoto 675SS with its incredible price of $ 8,000.
But the king of the three-cylinder middleweight sports bikes is without a doubt the Yamaha YZF-R9. It offers more power and just as many functions (including launch control and MotoGP wings) as the Aprilia for just $ 700 more. And for less than the YAM, the Basic Ducati Panigale V2, a Premium Italian middleweight sports bike that combines practical, lightweight, a two -cylinder engine and sportiness with an amazing electronics suite. That sounds very famous …
