Aprilia RS 125 R osso Fluo (2008)

The wait is finally over for US enthusiasts, as Aprilia’s stunning RS 125 R osso Fluo makes its long-awaited debut in the American market. But don’t expect to ride it on public roads – due to EPA emission standards, this track-only marvel will be strictly reserved for closed-course events.

But what a track-day companion it promises to be! The liquid-cooled, 125cc Rotax engine is a masterpiece of two-stroke engineering, delivering its power via a 28mm DellOrto carburetor and reed valve intake. And with a sleek exhaust system, razor-sharp magnesium triple clamp, polished frame, and multi-spoke wheels, the RS 125 R osso Fluo is as visually stunning as it is agile.

Throw in an ultra-light dry weight of just 280 pounds, courtesy of its rigid GP-inspired aluminum frame and suspension setup featuring a 40mm inverted fork and hydraulic rear shock, and you have the perfect recipe for a thrilling track-day experience. Whether navigating twisty circuits or pushing the limits on the straights, the RS 125 R osso Fluo is sure to leave riders grinning from ear to ear – and begging for more!
