2017
The 2017 Aprilia RS4 125 Replica carved its niche as a highly desirable small-displacement sportbike, inheriting the racing DNA of its larger RSV4 siblings. This model continued Aprilia's tradition of offering premium 125cc machines, appealing to younger riders or those seeking a lightweight, agile sportbike experience. In a competitive segment, it went head-to-head with rivals like the Yamaha YZF-R125 and the KTM RC 125, distinguishing itself with its unmistakable Italian styling and genuine race-replica feel.
At the heart of the RS4 125 Replica was a potent 124.8 ccm (7.62 cubic inches) single-cylinder, four-stroke engine.

Torque figures were equally impressive for a 125, reaching 10.9 Nm (1.1 kgf-m or 8.0 ft.lbs) at 8250 RPM, ensuring responsive acceleration through the gears. With a generous fuel capacity of 14.50 litres (3.83 US gallons), the RS4 125 offered a respectable range for daily commutes or weekend excursions.
Riding the RS4 125 Replica was an experience crafted around sportbike principles. Its track-focused ergonomics, characterized by clip-on handlebars and rearset pegs, placed the rider in an aggressive, aerodynamic posture. This setup, combined with a seat height of 820 mm (32.3 inches) (at its lowest setting, if adjustable), provided excellent feedback and control, making it a joy to lean into corners. The lightweight chassis and responsive suspension further contributed to its agile handling, allowing riders to confidently navigate twisty roads or even a track day.
