2012 Aprilia RS4 125 - This has got to be one for the youth of the world wanting to ride a sportsbike - Aprilia is updating the 50 and 125 cc versions of its Aprilia RS4 for 2012. More attention is being paid to the technology equipping these smaller sportsbikes for young riders as racing culture and its associated technology starts to feature across the range.
2012 Aprilia RS4 125 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 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 2012 Aprilia RS4 125 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 2012 Aprilia RS4 125 main frame is of a twin-spar aluminum design with a 41mm inverted fork up front and a shock absorber out back mounted directly to the swingarm. Braking components consist of a solo 300mm disc and a four-piston radial mount caliper up front and a 218mm disc and single-piston caliper rearward. The RS4 rolls on 17-inch six-spoke wheels with tubeless tires.
The design of the fairings and tank, the unique looks of the front end, with the headlights suspended over the gaping air intakes, and the spectacular tapered tail fairing are identical to their counterparts on V4 1000 cc supersports model that set new standards in terms of style and technical content for the superbike segment.
Extensive aerodynamic studies have minimised surface areas without compromising wind protection, and the fairings showcase the superlative mechanicals of the 2012 Aprilia RS4 50 and 2012 Aprilia RS4 125 rather than conceal them. As a result, the frame and engine are not hidden away but proudly flaunted as fundamental elements of the design of Aprilia’s new small supersports models. With the triple headlight, the Aprilia RS4 bikes have a decidedly aggressive look that lends a unique character to the entire front end. The LED taillight merges stunningly into the ultra-compact tail fairing and offers excellent luminosity.
