Aprilia RS 660

The sleek and sporty RS660 carves out an identity of its own, apparent in its sharp twin LED headlamps and the DRL with integrated turn indicators, that seamlessly merge with the creases on the front fairing. The side fairing looks equally arresting with its cuts and creases, while the exposed aluminium frame stands exposed in a typical Aprilia sort of way. The new Aprilia RS 660's new Euro5 compliant, 659cc, parallel-twin engine is derived from the Aprilia RSV4's V4 engine. This twin-cylinder engine has a 270-degree firing order and produces 100hp at 10,500rpm and 67Nm at 8,500rpm.
