The Speedster Swepts create a deep rumble that improves the sound but keeps the noise down. The sweeping lines follow the curved shapes of the motorcycle for a great look. Like all Cobra Speedsters, the Swepts include the Cobra PowerPort for increased low and mid-range power. They are equipped with full length 2.5-inch heatshields which wrap around 222 degrees and cover the 1.75-inch headpipes. Of course they also have the Cobra Limited Lifetime Warranty.
