The Gilera Runner is a scooter manufactured by Italian company Piaggio under the Gilera brand, designed by Luciano Marabese of Marabese Design Srl. It is noted for its unusual style, high performance and good handling. The Runner was initially only available with two stroke engines with 125 cc and 180 cc four stroke versions arriving in 2001 and the larger two stroke versions phased out. The model range was revised in 2005 with an all new model introduced in 2009. All 50 cc Runner models were restricted to 28 mph (45 km/h) to comply with European law. The 125, 180 and 200cc models were not restricted.

The first incarnation of the Gilera Runner was a 50cc that was released in 1997 in Europe. The 50cc model went through a number of revisions; in 1998, a rear disc brake was added with the Gilera Runner 50DD (Double Disc). The colour scheme was also revised with the release of the Runner 50SP. The direct injection Runner Purejet 50 was released in 2003 with lower emissions.

In 1998, the 125 cc (7.6 cu in) FX Runner was introduced which had the same styling as the 50cc. In 1999, the SP model was released. The biggest difference between the FX (FXR) and the SP is the FX had a 9 l (2.0 imp gal; 2.4 US gal) petrol tank and battery stowed near the spark plug and a rear drum brake. The SP has a 12 l (2.6 imp gal; 3.2 US gal) petrol tank, the battery is stowed under the seat and it has a rear disc brake.

In 1999, the FXR 180 cc (11 cu in) was introduced and was by far the fastest of the Runners including the new generation 200 cc (12 cu in) four strokes. It was noted for its high performance and great handling. Unfortunately it has a high fuel consumption.
