In 1992, the Italian motorcycle manufacturer released the Aprilia RS 125 Extrema, an entry-level, small-displacement sports motorcycle, perfect for young riders starting the two-wheeler journey.
The bike featured an angular tail section, a swept front fairing, a square headlight unit, three-spoke aluminum wheels, air scoops carved on the upper front middle fairing, an electric or kick starter on the left side, and analog gauges.
The bike was built around an aluminum frame with a 40 mm inverted telescopic fork on the front, offering 120 mm of travel, and a single shock absorber on the rear, providing 120 mm wheel travel.
The braking performance was controlled by a single 320 mm disc on the front wheel tied to a four-piston caliper and a 240 mm disc bolted to the rear wheel squeezed by a dual-piston caliper.
As for the Power figures, the 1992 Aprilia RS 125 Extrema had installed a 124cc two-stroke single-cylinder liquid-cooled engine that delivered an output power of 34 hp with a peak force at 11,000 rpm and 24 Nm (18 lb-ft) torque at 9,000 rpm.
