| Aprilia's profilation of this bike |
| 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. |
