The Aprilia RS 660 Extrema embodies the pinnacle of sport bike performance, blending razor-sharp handling with exhilarating power.
Built on the success of the best-selling RS 660 in Europe, the Extrema takes the cake as the sportiest and lightest variant yet. At just 166 kg curb weight, this marvel of engineering boasts a remarkable weight-to-power ratio of 100 HP – an unprecedented feat in its class. The star of the show is undoubtedly the SC Project exhaust system with carbon silencer positioned on the right side, shaving precious pounds from the overall weight.
As you settle into the cockpit, the Extrema’s new standard equipment reveals itself: a black anodized aluminum silencer bracket allowing for passenger foot peg removal, a revised front mudguard, and a sleek belly pan with innovative design. The result is an unbridled riding experience that seamlessly merges track prowess with everyday usability.
This is not just a motorcycle – it’s the culmination of Aprilia’s ingenuity in crafting a machine that defies categorization.
