The Aprilia SL1000 Falco (also known as "Aprilia SL Mille PA"), is a sports motorcycle powered by a liquid-cooled 996 cc 60° V-twin engine, manufactured from 1999 to 2003 by Aprilia in Noale, Italy. The Falco's 118 hp (88 kW) engine was a detuned version of the 128 hp (95 kW) RSV Mille engine, whereby dual exhausts and remapped fuel injection cropped the peak power slightly but bolstered bottom and mid-range.
The Falco has a half-fairing, a twin-beam alloy frame, 53 mm USD forks from Showa (& later Marzocchi) and twin Brembo 320 mm semi-floating front brake discs. The clutch had a device, activated by inlet manifold vacuum, that simulated a slipper cluth.The Falco was not as radical as the "race-replica' Mille nor really a sports-tourer (such as their own Aprilia Futura), but was instead a very sporty roadster, competing in the market against the Honda VTR1000, the Suzuki TL 1000S and the Ducati ST4.Although the Falco proved a reliable and powerful sports bike, sales were disappointing and production ceased in 2003, with sales continuing into 2004.
