Aprillia RS4 50

Aprillia RS4 50

Aprilia offers the innovative Aprilia Quick Shift system, a sophisticated technical solution derived directly from its big sister, the RSV4 APRC.

Aprilia introduces two brand new small engine super sport bikes intended for young bikers and the fruit of extraordinary technical and sport experience which has brought the brand from Noale to be the most victorious Italian and European manufacturer of motorcycle brands active in world competitions.

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.
