Power Commander V. Full Akropovic exhaust. ASV clutch and brake levers. K & N air filter. Brand new Vortex chain and sprocket kit. Just had motor rebuilt at 2,822 miles. This bike was previously a track bike and the owner blew a head gasket. I went ahead and replaced rods, pistons, valves, seals, bearings, and put an entire new gasket kit in it. Brand new motor basically and has surpassed break in period flawlessly. Minor dent in gas tank and small hole in exhaust from being scraped on the track. Other than that this bike is phenomenal, plenty of power and rides great.
