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.
Every weekend, all over the world, Aprilia bikes take to the track, from international venues to local races, holding high the honour of Italian and European motorcycling, supporting the biker's desire to race and cultivating young riders destined to enter the world championship scene.
Aprilia has always drawn from this wealth of success and technical skills for mass production – both in the philosophy which inspires the product and the aesthetics which are often taken from the racing bike – establishing itself from the start as an absolute leader in the 50 and 125 super sport segment, categories in which the Noale brand has introduced timeless innovative concepts and solutions and dictating trends which would be followed by all of its competitors.
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.
