The 2015 Sportster 1200 Custom we tested had a few goodies from the H-D1 factory custom shop  from its mini-apes and paint scheme to ABS.
ECUnleashed is offering its Performance Reflash for Harley-Davidson Sporster 1200s the company claims will “unleash up to 6-10% more power.”

ECUnleashed Performance Reflash enhances the experience in every ride by offering more power by eliminating factory restrictions, optimizing fuel, ignition & throttle mapping, increasing rev limit, and removing the top speed limiter. This is achieved while delivering better response and control through eliminating the factory fuel cut-off and optimizing the off throttle deceleration mapping. This reduces engine braking and delivers smoother, more predictable on/off throttle transitions.
