Aprilia RS4 125 GP Replica

Symbol of Aprilia’s sport DNA, RS 125 Replica GP has been profoundly revamped to celebrate twenty-five years of success.

Aprilia RS 125 Replica GP is still the point of reference for sport bikes dedicated to younger riders, a concentrate of content and style, ready for the best performance on the road and on the track.

Born out of racing, aggressive, capable of expressing dynamic character and light weight in a personal and recognisable style, RS 125 Replica GP highlights Aprilia’s passion for sport with a concentrate of technological refinements worthy of a true Superbike. Exclusive ergonomics of a true super sport bike, sleek fairing, aluminium frame, a generous engine and the best components and technical features.

Technological beating heart

The beating heart of the Aprilia RS 125 Replica GP is a modern and technological 125 cc single-cylinder, 4-Stroke, 4-Valve electronic injection engine with liquid cooling: reliable on the road and powerful on the track, it has particularly refined technologies such as double overhead camshaft timing (DOHC). With ultra-modern conception and design, lightweight and compact, it has allowed development of a refined chassis. Its power, optimally calibrated, guarantees responsiveness even at low revs. Vibrations are reduced to the minimum by a balancing countershaft. Euro 4 approved, it guarantees environmentally-friendly top performance.

The 2017 MY RS 125 is installation-ready for Quick Shift, the innovative gear shifting system that Aprilia has used and perfected on tracks all over the world. Just like with its big sister, the RSV4, the electronic system manages torque interruption for the engaged gear change, how far the throttle is open and the engine revs, allowing the rider to upshift while holding the throttle open and without using the clutch.

The exhaust, which is unmistakably racing inspired, is completely integrated within the lower part of the fairing. A solution with a strong aesthetic impact that effects the dynamic performance of the vehicle, based on the centralisation of the masses.

Unique ergonomics, benchmark chassis

The general ergonomics of the Aprilia RS 125 Replica GP are designed for the track. No other 125 can convey a racing character like the eighth-litre from Noale. The riding position on the RS 125 Replica GP is unique: the semi-handlebars, forward-mounted lower than the steering yoke and the set-back footpegs, along with the saddle-fuel tank assembly, ensure a true super sport riding position without compromise.

The solid upside-down fork and the rear suspension with racing-derived monoshock secured to the asymmetrical swingarm ensure performance, top level safety and comfort. The split 6-spoke design of the wheels emphasizes the purposeful character of the RS 125 Replica GP. A configuration that is once again merit of racing experience that ensures light weight and speed going into corners. The braking system uses a four-piston radial calliper on the front wheel, assisted by Bosch single-channel ABS, that grips a 300 mm diameter steel disc. The rear mounts a single-piston calliper that grips a 220 mm disc and has a tone wheel to guarantee anti roll over protection. Maximum performance and safety at every braking point. The license plate mount and turn indicators can be easily removed for track use.

Compact and ultra-lightweight, the new instrument cluster provides all the functions of true racing instrumentation: from the analogue Rev. counter to the multifunction digital display with handlebar controls for the speedometer, trip master, battery voltage, time and stopwatch with memory for 20 laps, cooling circuit temperature indicator and fuel reserve indicator, OBD warning light and ABS fault warning light. The AMP ECU that enables connectivity between the bike and your smartphone is also available as an accessory.
