Aprilia Rs 660
The Aprilia RS 660 was introduced in 2020 as a production model after debuting as a concept at EICMA 2018, marking Aprilia's return to the middleweight supersport segment. It uses a newly developed 659cc parallel-twin engine derived from the RSV4's front cylinder bank, blending accessible performance with advanced electronics typically found on superbikes. The RS 660 quickly gained acclaim for its sharp handling, lightweight chassis, and premium feature set, revitalizing interest in the middleweight class and spawning sibling models like the Tuono 660.

What Buyers Should Know
Parallel Twin Engine
The RS 660 uses a 659cc parallel-twin derived from Aprilia's RSV4 superbike, giving it genuine performance DNA. It produces 100hp at a lightweight 169kg wet weight, making it exceptional for its class.
Watch the Throttle Body
Some early 2021-2022 models reported throttle body calibration issues causing rough idle and hesitation, often resolved via a dealer ECU update. Always verify the software version is current before buying used.
Strong Resale Value
The RS 660 holds its value notably well due to limited production numbers and high demand relative to supply. Used examples often sell within 10-15% of original MSRP even after 2-3 years.
