Aprilia RS 125 (2021)

Aprilia RS 125 (2021)

The Aprilia RS 125 embodies the Italian marque’s passion for outstanding performance, marrying aggressive styling with finely-tuned engine and cutting-edge technology.

Its lightweight yet robust aluminium frame, a world-first design by the Aprilia Racing Team, sets the tone for exceptional handling and stability on both road and track. The chassis is completed by an upside-down fork and single shock secured to the asymmetrical swingarm, delivering outstanding ride dynamics.

At its heart lies a 4-valve, liquid-cooled single cylinder with revamped thermodynamics, producing a robust torque curve with maximum power reached at lower revs for reduced fuel consumption. Euro 5-compliant, this engine promises exceptional performance without environmental compromise.

The riding position is designed to be truly sporty, with no compromises taken – the foot pegs are carefully positioned to avoid fatigue, and the handlebar placed for total control, complete with raised clip-ons for greater comfort.
