Doing research, looking at the new Sporter customs, since they now have a stiffer frame and rubber isolation on the engine so they don't vibrate like the 2003 and earlier sports. Plus they have the bigger tanks and look great. This will be my first bike and I want to know if anyone has owned the sports and is there a big difference between the power of the 1200 or the 883. Also if I got an 883 I understand you can increase the power with a 1200 kit? What does that cost?
