Aprilia AF1 125
Aprilia's first purpose-built sportbike homologated for the 125 cc GP class. Its chromoly steel trellis frame, single-cylinder two-stroke engine with rotary disc valve, and aggressive fairing inspired by the GP machines of Loris Reggiani made the AF1 the most desirable 125 in Europe.
