n 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.[3]
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.[3] It was noted for its high performance however handling was poor and fuel consumption high.[1]
