2011 Aprilia RS4 125
Aprilia's small supersports bikes have been completely revised. Two models dedicated for young enthusiasts who want their first experience in the motorcycling world to be with a proper bike. Aprilia RS4 marked a milestone in the evolution of the 125 cc motorcycle. For the first time ever, the sportiest bike available for 16 year olds was a 4-stroke. For the youngest riders of all, the Aprilia RS 50 embodies all of Aprilia's technology in a genuine racing replica in just 50 cc. Aprilia has always been the undisputed leader in the 50 and 125 cc supersports segment, pioneering innovative concepts and solutions and setting trends for its rivals to follow. Aprilia RS 50 and Aprilia RS4 125 take the concept of the sports bike for novice riders who want to enter the motorcycling world with a proper bike to new levels of technological sophistication. The Aprilia RS4 125 is the natural successor and most advanced evolution to date of the Aprilia RS 125, the bike that has dominated the 125 cc sports class for years, which set the benchmark for the one-eighth litre sports segment and which is still today the most highly sought after machine among riders competing in the Sport Production category. Aprilia RS4 125 introduces the highly advanced, all-new 4 stroke powerplant to the sports segment, while adopting styling and technical solutions inherited from the RSV4, the superbike that led Aprilia to victory in the WSBK 2010 championship.
With the new RS 50 and RS4 125, Aprilia confirms its global leadership in the small capacity sports bike segment, creating models that exceed the expectations of even the most discerning rider. The sophisticated chassis architecture of the Aprilia RS 50 and RS4 125 is complemented by state of the art engines. The single cylinder 50 cc unit developed by Aprilia for the RS 50 is a water cooled two-stroke with reed valve induction. The lubrication uses a separate mixing system with a variable capacity volumetric pump. The six speed gearbox lets the rider make full use of the performance of this class beating engine. The Aprilia RS4 is powered by an all new 125 cc water cooled 4 stroke single cylinder engine with four valves and electronic engine boasting a sophisticated double overhead camshaft (DOHC) valve timing system. This state of the art engine produces the maximum power output permitted for the class with a smooth, linear delivery and ecologically - as it meets even the strictest emissions regulations in effect. With a six speed gearbox allowing the rider to make full use of the power available in all conditions, the Aprilia RS4 offers unbeatable performance in its class not just in terms of absolute power at high engine speeds, but also in terms of usable power band, minimised vibration and outstanding mechanical reliability. The product of a cutting edge design, the new single cylinder 125 cc unit features dry sump lubrication making it extremely light and compact, allowing Aprilia's engineers to develop a class beating chassis layout.
