2009 BMW R 1200 GS

The RS 660 takes fun and performance levels up another notch with a selection of new racing elements designed to reduce weight and enhance its dynamic qualities.

PERFORMANCE

Among the key latest features is the SC Project exhaust, which combines with a new carbon lower fairing designed especially for this model, along with the front mudguard, also in carbon. And the result? A reduction of an impressive 6.6 lbs compared to the classic Aprilia RS 660. Less weight means more riding fun!

DESIGN

The Aprilia RS 660 raises the bar yet again. After reinventing the medium-cylinder sports category, the Extrema version shakes things up once more, injecting another healthy dose of sports personality into the mix with an exclusive chequered flag livery and single seat cowl.

TECHNOLOGY

The Aprilia RS 660 Extrema also ups the ante when it comes to technology, courtesy of reverse gear software, a great element if you’re not only concerned about aesthetics, but are also looking for a true Racing bike set-up.
