Top Speed of Aprilia Rs 660

Alberto Beggio founded the Italian motorcycle Aprilia RS (RennSport)after world war two, and now Piaggio Group owns it. It is one of the lightest and slimmest bikes to ride, even though it weighs 403 lb and gives a smooth road experience. The design is fantastic and comfortable for sitting; you can proudly call it a sports bike. Even if you are short in height, you can easily sit on the bike without stretching out your body, and the ride quality is excellent.

They offer exciting color schemes like Apex Black, Lava Red, and Acid Gold. There are many qualities of the ride, but there are some shortcomings, also. You may face difficulty while turning around, also but you can face oil leakage even after three weeks of buying. That bike is perfect for beginners as it has comfortable sitting, smooth ride, ABS, and traction control.

What is the Top speed of the Aprilia RS 660?

The top speed of the Aprilia RS 660 is around 142 mph(230 kph). This bike produces 67 Nm @ 8500 rpm of torque and has a power of 100 PS @ 10500 rpm. Knowing that this bike weighs 403 lbs, its top speed is exceptional. Aprilia RS 660 comes with a 6-speed transmission gearbox, making the ride smooth and comfortable on different terrains.

Aprilia Provides A Great Riding Experience

One of the best things about the ride is the unforgettable sitting experience, which is quite comfortable. The low seat is a plus point for every passenger, especially for short people or if you have a painful body and can’t stretch all your body. It has a seat height of 815 mm(32 0 in). The seat of the Aprilia RS 660 is quite similar to the Honda Grom. However, the latter is shorter in height.

The pegs are lower; the knees are closer, are the body is slim. While standing on the pegs, your shoe won’t slip as it has high gripping power. The perfectly balanced saddle, footpegs, and handlebars distribute the body weight equally.

Engine

Although the Aprilia RS 660’s 100 horsepower may not surpass the Yamah R6’s Top speed on a straight road, it compensates for it with its exceptional midrange torque, making it capable of holding off the super sports for a considerable amount of time post-apex. The engine performance is not crazy but exhilarating, with a vast power spread and a distinct V-twin-like roar. There is ample low-end torque, offering a gear choice for each turn.

The rider can let it lug and ride the torque wave off the apex or rev it out and make it howl, thanks to the engine’s flexibility and forgiving nature. While the sound and vibrations may vary depending on the RPM, the Aprilia’s 659 cc twin engine produces consistent acceleration throughout the entire rev range until it reaches the rev limiter at 11,500 RPM.

Furthermore, the standard quick shifter enhances the Aprilia’s track prowess, while the slipper clutch controls back torque during hard braking, maintaining stability while entering corners. These top-of-the-line features can be fully utilized and enjoyed on the track.

Suspension & Handing

Aprilia equipped the RS with an adjustable suspension made by KYB for the fork and shock. They also adjusted the bike to make it perform better on the track, such as increasing the spring preload and moving the forks up in the triple clamp.

They also replaced the standard tires with Pirelli Diablo Superbike slicks for better grip. The bike was lightweight and easy to handle, and the suspension worked well with the bike’s power and weight. Although it could have been better for hard braking and aggressive cornering, the bike didn’t feel unstable when pushed hard on the track.

Brakes

Aprilia R6 Brakes

Aprilia equipped the RS 660 with powerful brakes, but Chuckwalla track’s layout needed to allow testing them to their maximum potential. Nonetheless, the brakes are strong enough to lift the rear wheel and provide enough feedback to comfortably brake to the lean angle.

The initial bite on the brakes is not as strong, which is more noticeable on the track where inputs are quick and forceful. Upgrading to more aggressive brake pads like the Galfer HH pucks could improve this, but it may require further tuning of the fork. Overall, the RS’s brake system is impressive and well-matched to the suspension setup. The bike also features front-only ABS for track use, making it suitable for all-out track riding.

Electronics

One of the RS 660’s standout features is its advanced electronics package, which includes a large TFT dash with a lap timer, ABS informed by an IMU and a bi-directional quick-shifter. However, the digital tachometer is challenging to read at a glance compared to an analog setup. The bike’s TC is adjustable on the fly, but it was unnecessary, with the Pirelli slicks providing excellent grip.

The dash occasionally displayed a warning indicating the ATC was disabled. Still, since it was a pre-production bike with a new Magnetti Marelli ECU, Aprilia stated a fix was already in the works. Despite some minor teething issues, the bike’s advanced electronics are impressive.

Final Thoughts

The RS 660 is a competent and versatile bike that any rider can enjoy, whether a novice or an experienced road racer. Personally, riding the bike was an exhilarating experience not only because of how well it performed but also because I was able to utilize its capabilities thoroughly. In comparison, I’m not doing justice to the performance of a 600 or 1000-cc bike.

While it’s true that the Aprilia may have a lower performance threshold than a Yamaha YZF-R6, its slightly lower power output is much easier to access and use. A novice track-day rider would be faster on the RS 660 than on a 600. Moreover, the RS 660 is an excellent street bike that can be used when you’re not on track.
