2023 Aprilia RS 660 Extrema

2023 Aprilia RS 660 Extrema sits at the top of the RS 660 range, positioned as the sharpened, track-focused version of Aprilia's middleweight sportbike rather than a bigger-displacement machine. This is a bike built for riders who want the RS 660's usable, revvy parallel-twin character but with a chassis and electronics package tuned toward canyon roads and track days rather than commuting. It rewards a rider who wants to carry corner speed and use the rev range, not lug around at low RPM, and it feels compact and eager rather than intimidating the way a liter-class superbike can. Day to day, it's the kind of machine you can ride hard on a Sunday and still trust getting you home afterward.

The 2023 model carried over without significant mechanical changes from the prior year, buyers comparing it to a 2022 example should focus on mileage, service history, and condition rather than spec differences. No recalls apply specifically to the 2023 Extrema.

Expect buyers who already ride sport bikes and want something more focused without stepping up to a full liter-class machine, often trading down from a heavier sportbike for something lighter and easier to exploit on real roads.
