The RS4 125 – the first Aprilia sport bike in this engine class with a 4-stroke engine – and the RS4 50 allow young enthusiasts to take advantage of the maximum levels of technological innovation, chassis efficiency, active safety and component quality. They belong – not only from a styling point of view – to the same range of extremely high performance Italian motorcycles in which the Aprilia RSV4 stands out, the extraordinary bike which conquered two world titles in the 2010 Superbike season.
APRILIA SPORT BIKES: WINNING DNAIn its short history, Aprilia has earned 48 world titles (37 in Moto GP, 2 in Superbike, 9 in off-road competition) and hundreds of championship races, to become the most victorious Italian and European brand in just a short period of history in Moto GP.
It is precisely in the youngest classes of Moto GP that Aprilia established itself as a true "school of champions". On Aprilia 250 and 125 bikes in the RS series (RS, RSV, RSW and RSA) riders such as Biaggi, Rossi, Melandri, Stoner, Lorenzo rode to their first great triumphs.
From 1993 until today, more than 100,000 Aprilia RS 125 two stroke bikes have been manufactured and sold in more than 30 countries around the world.
