The first high performance narrow V four cylinder engine in the world; the most revolutionary engine ever made by Aprilia is incomparable thanks to its unique "total electronics" package, its incredible lightness and super compact size, reaches a new stage in evolution. The engine has been updated and improved with particular attention paid to reducing internal friction and increasing casing ventilation. The exhaust system too has been remodeled to provide maximum performance working in combination with a finely tuned electronic management system. This brings the maximum power of the 65° V4 to 184 CV with torque now arriving at 117 Nm. The 3 distinct mappings (Track, Sport and Road), were matched to the new power and torque specifications of the V4 to provide even fuller and in-depth power output at any engine speed.
