The Aprilia AF1 125 Sintesi Sport is a small motorcycle with a two-stroke, single cylinder engine of 124.7 cc. The engine has a Gilnisil-coated aluminum barrel and a 15.1:1 compression ratio. The bike uses liquid cooling and a 28 mm Dell’Orto carburetor for induction, and electronic ignition for starting. It has a maximum power output of 21.4 kW at 10,500 rpm and torque of 18.6 Nm at 10,000 rpm. The 6-speed transmission and chain-based final drive system serve to deliver power to the bike’s wheels. The suspension system is comprised of a telescopic fork (with a 38mm shaft) at the front and an Aprilia progressive mono-shock system (Sebach suspension) at the rear, both of which provide a wheel travel of 120 mm. Braking on this motorcycle is taken care of by a Brembo four-piston caliper system with a single floating 320 mm disc at the front and a two-piston caliper system with a single 240 mm disc at the rear. The bike has a seat height of 800 mm and mounts a 100/80-17 front tyre and a 130/70-17 rear tyre. This bike was released in 1990.
