The Aprilia RS4 50 Replica is a sporty compact bike that draws inspiration from its bigger displacement brothers that dominate the race tracks. Therefore, the Aprilia RS4 50 Replica, features a lot of lines and shapes borrowed from the Aprilia RSV4 Factory super sports bike.

Jump on board and you’ll be greeted by an analogue/digital multifunction dashboard inspired by that of the RSV4, with analogue rev counter and LCD Screen for all other information. For enhanced practicality, the motorcycle features a removable shell which transforms it from a two-seater into a single-seater.

Power comes from Aprilia’s single cylinder, two stroke, 49,9 cc liquid cooled engine which is mated to a six speed transmission.

The bike is priced at € 4.080.

For young potential champions

The Aprilia RS50 Replica caters for the more precocious bikers, those tired of parking their bicycle in the garage next to father’s or older brother’s motorbike, who recognise the bike from the noise of the exhaust, who stay glued to the TV to watch the duels until the last pull away between the great champions of motorcycling. For them the first real motorcycle can only be an Aprilia, the most racing of all 50cc’s: the RS4 50 Replica.

A race replica in 50cc
Also the small Aprilia RS4 50 Replica, as its bigger 125 sister, recalls - both in the livery as well as in the importance of the shapes - the appearance of the Aprilia RSV4 Factory super sports bike, starting from its extremely sport-like fairing. As for its bigger sisters, also the RS4 50 Replica shares the racing livery, with the front profiles of the sides embellished with the colours of the Italian flag and stickers of the technical sponsors, Eni and Dell’Orto. The removable shell transforms it from a two-seater into a single-seater, like a true racing bike.

Everything under control
Also the RS50 Replica has an analogue/digital multifunction dashboard inspired by that of the RSV4, with analogue rev counter and LCD Screen for all other information, from the speedometer to information on the parameters of its generous 50cc engine,

A place for everything.
An extremely refined feature of the RS4 Replica is the passenger seat. The transformation from a two-seater to a single-seater takes place without the complicated removal of screws but only via a quick release/attachment button that allows the passenger seat to be replaced with the tail cover (available as accessory) in seconds. Under the saddle, moreover, there is space for a practical storage compartment, the largest in the category.

The 50 2stroke engine: Little pest
The 50cc single cylinder engine developed by Aprilia for the RS4 50 is a two-stroke, liquid cooled engine with reed intake valve. Lubrication is with separate mixing with variable displacement volumetric pump. The six-speed gearbox makes the most of the performance of an engine at the top of its class, a little pest ready to face any challenge.

World championship frame
The frame is undoubtedly the flagship of the RS4 project: created based on the exceptional experience acquired by Aprilia in the WSBK and in the 125 and 250 classes of the MotoGP, it adopts die-cast beams in aluminium alloy with cross-ribbing reinforcement. A lightweight structure, able to offer a high torsional rigidity and which stands out for its avant-garde design.

Curbs any excesses and absorbs everything
Also the front suspension is high level with a robust 41 mm upside-down front fork with black anodised sheaths and 110 mm stroke, while at the rear is a single shock absorber directly fixed to the asymmetric swingarm. The RS4 50 Replica has the same powerful braking system as the 125 sister, at the front a 300 mm diameter steel disc with four-piston radial caliper, supported at the rear by a 220 mm disc with single-piston caliper. The 17” rims mount 100/80 tyres at the front and 130/70 tyres at the rear.
