The Aprilia RXV 550i for 2008 embodies the pursuit of perfection in off-road competition. Drawing from the expertise gained in the Enduro World Championship and invaluable insights from four-time world champion Stefan Merriman, Aprilia’s engineers have crafted a formidable machine.
Aerodynamic refinements and aggressive styling cues give the RXV a menacing presence on the track, while significant weight reduction – down to 113 kg dry – enhances agility and responsiveness. Ergonomic upgrades, including a sleek new fuel tank and revised handlebars, optimize rider comfort and control.
At its heart lies a potent, liquid-cooled four-stroke V-twin engine, delivering robust power and torque in equal measure. Mated to an advanced suspension system featuring a 45mm upside-down fork and monoshock rear unit, the RXV is poised to conquer even the toughest terrain with confidence and finesse.
