Rider Profile

Best For	This restricted-power variant of the RS 660 is well suited to newer licence holders or those on power-capped licences who still want sharp sportbike handling.
Purpose	It's built primarily for spirited cornering and sporty road riding rather than outright top-end speed, thanks to the detuned 46.9 HP twin in a lightweight chassis.
Rider Fit	The low, compact chassis and moderate seat height make it accessible, though the sporty riding position still puts noticeable weight on the wrists during long stints.
Character	Agile, light, and eager to change direction, this bike rewards smooth inputs and flowing cornering lines more than brute acceleration.
Not Ideal For	It's not the right choice for riders wanting high-speed highway overtakes, long-distance touring comfort, or any kind of off-road capability.

Units

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 820mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2026 Aprilia RS 660 35KW, with a cramped knee angle of around 70 degrees and a forward-leaning riding position.

Data quality: measured. Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
