Aprilia RS4 50 Replica (2015)

The Aprilia RS4 50 Replica is a miniature marvel, inspired by the championship-winning RSV4 SBK 2014 and featuring a sleek silver livery adorned with Marco Melandri’s iconic number ’33’. The bike’s aggressive stance is further accentuated by its LED taillight and “Racing” integrated design. Underpinned by Aprilia’s extensive competition experience, the RS4 50 Replica boasts a robust die-cast aluminum frame with cross-ribbing reinforcement.

The heart of this diminutive dynamo is a potent single-cylinder two-stroke motor, delivering a thrilling ride experience with its valve induction and separate lubrication system. With its six-speed gearbox and liquid-cooled design, the RS4 50 Replica offers an exhilarating blend of power and agility.
