Two Stroke Models
The first incarnation of the Gilera Runner was a 50cc that was released in 1997 in Europe, but was restricted to 28 mph (45 km/h) to comply with European law. 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 Runner Purejet 50 was released in 2003 with lower emissions. The 50cc is the only two stroke in the current Gilera Runner line up with two versions available; Runner 50 SP and Runner Simoncelli 50 SP.
In 1998, the 125cc 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 litre petrol tank and battery stowed near the spark plug and a rear drum brake. The SP has 12 litre petrol tank, the battery is stowed under the seat and it has a rear disc brake.
In 1999, the FXR 180cc was introduced with a top speed of around 85 mph (137 km/h) and was by far the fastest of the Runners including the new generation 200cc four strokes. It was noted for its high performance and great handling. Unfortunately it has a high fuel consumption.

Famous quotes containing the words stroke and/or models:
“The five kings count the dead but do not soften
The crusted wound nor stroke the brow;
A hand rules pity as a hand rules heaven;
Hands have no tears to flow.”
—Dylan Thomas (1914–1953)
“Friends broaden our horizons. They serve as new models with whom we can identify. They allow us to be ourselves—and accept us that way. They enhance our self-esteem because they think we’re okay, because we matter to them. And because they matter to us—for various reasons, at various levels of intensity—they enrich the quality of our emotional life.”
—Judith Viorst (20th century)
