The Sportster's Evolution engine, first in 883cc and later in 1200cc form, was only one of the improvements to this model since H-D's separation from AMF.

Floating disk brakes, fully adjustable suspension, and alloy wheels made the Sportster a real sportbike. But some owners wanted even more canyon-carving power. From the Sportster, and sharing many of its components, came the Buell sportbike.

Our products work on both to enhance performance. Super Port Flow will eliminate detonation and add a LOT of power. A blueprinted Keihin carb and low-restriction air filter will complete the breathing improvements to your engine.

If that isn't enough, add Dual Plugging for maximum power. Put it together with our Dual Coil Ignition Kit and practice keeping your front wheel on the pavement.
