The bike soon

Created to celebrate the success of Bulega Sport Production championship in 1989, except for successful coloring, Sports AF1 AF1 is practically identical to the 1989 Summary. The only notable difference 'represented by a colored plastic shell (removable by turning a screw) that covers the passenger seat. Interestingly, the AF1 Sport and 'the only Aprilia Sport Production racing thought to have mount a 34mm carburetor fact, from 1992 versions marketed to race in the SP will necessarily fit a 28mm.
