  Aprilia的2衝125擁有悠久的歷史,至今仍未停產,在2011年,Aprilia推出4衝版的RS4 125,外型啟發自同廠的旗艦跑車RS4V。車廠為了慶祝庇亞基(Max Biaggi)在2010年奪得首個WSBK世界冠軍,2011年追加推出擁有相同的意大利航空公司拉花RS4 125。

雖然庇亞基(Max Biaggi)在2011年奪冠的美夢落空了,但今年WSBK的表現卻氣勢如虹,完成超過一半賽季後,以248,5分排在榜首位置,比BMW車隊的同鄉米蘭迪(MARCO MELANDRI)高40分。庇亞基(Max Biaggi)能否保持優勢仍是未知之數,但車廠已急不及待追加2012 WSBK意大利國旗拉花RS4 125 。

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.
