Dr. Jekill & Mr. Hyde proudly presents the LUX for the Harley-Davidson Nightster. The Nightster is the next evolution from the legendary Sportster models. Driven by the Revolution Max 975-engine, this water-cooled V-Twin should not be underestimated. Be the first to hit the road when the light turns green and see your fellow riders in the rear-view mirror. Now you can also be sure to be heard with the LUX, the newest electronically adjustable exhaust from Dr. Jekill & Mr. Hyde.
