Getting a '13 CCT this week and am concerned with accessories. Do the Victory 2" pullback handle bars make a significant change in riding posture? Does anyone have an opinion concerning the CCT flip windshield? Are the Kicker Premium speakers a good upgrade? Does the HID headlight make a difference in night vision? Does the Victory Sena Bluetooth communication headset work well? Is the Stage 1 exhaust worth the price? Thanks, any and all feedback is greatly appreciated.
