Engineered by Aprilia for the sport motorcycle segment, the 2026 Aprilia RS125 features a 125 cc engine configuration. In factory specification, peak output is rated at 15 HP while maximum torque reaches 11.4 Nm. With a specific output of 120 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams.
