The 2023 Aprilia RS 660 Is An Intense Middleweight Sportbike

Aprilia is back again with their 660 cc lineup of motorcycles, including the RS 660 sportbike. Aprilia hasn’t highlighted any updates for the 2023 model year. However, a new model package is available to replace last year’s limited edition model.

As with the other 660 bikes among Aprilia’s lineup, the RS 660 utilizes a 659cc parallel-twin engine which makes 100 hp and just under 50 lb-ft of torque. Weighing in at a meagre 403 lb curb weight, we can see why this bike is considered such a track weapon.

The RS sits with a seat height of 32.3 inches, making it an extremely approachable bike for a lot of riders. Both the Kayaba front forks and the rear shock are rebound and preload adjustable, which is sure to make personalizing the bike a dream.

The Italian-built motorcycle features a state-of-the-art APRC system which makes riding this little monster so much easier. The APRC comes equipped with things like traction control and wheelie control, as well as a full suite of riding modes. A quickshifter is also standard.

The brand-new Extrema model is only available in a unique “checkered flag” livery. It also comes with an Sc Project exhaust and some carbon goodies, which Aprilia says has helped to drop the bike by over six pounds.

The standard model is offered in three colourways, Tribute (which is red, white, and purple), Racing Black, and Acid Gold.

The 2023 Aprilia RS 660 starts at $11,499 USD/ $13,995 CAD

2023 Aprilia RS 660 / 660 Extrema Features

RS 660 Limited Edition

The RS 660 celebrated its first significant competitive milestone with a special edition featuring a Stars and Stripes livery, enlarged top fairing, single-seat tail fairing and reverse quick shift gears. The result is a very special memento of all the victories in the 2021 Twins Cup, the prestigious American championship for midweight twin-cylinder motorcycles and considered the leading motorbike series in the States.


The RS 660’s clear-cut styling matches definitive performance

Aprilia RS 660 is immediately recognisable and rewrites the rule book for dynamic, modern sports bikes. Fundamentally innovate, purposeful and sophisticated, the new gem from Aprilia is endowed with a triple headlight and lines that speak the language of Aprilia sports bikes that have come before it – bikes which have made history while consistently winning over owners, racers and testers across the world…



When they got off the bike, the two journalists asked the same question: “When could I come back for another ride?“.

And you, how much do you want to get on an Aprilia RS 660?


Originally developed for use in racing then fine-tuned for the road, the APRC system is an advanced electronic control solution. It is a total package designed to ensure safety on roads and improved performance on the track.

The RS 660 boasts the latest APRC (Aprilia Performance Ride Control) package of electronic controls. This advanced inertial six-axis navigation system uses internal gyroscopes and acceleration sensors to understand the engine’s status as it relates to the road in real time and provide instant adjustments to help improve performance and safety.
