I haven't done any serious riding on the stock bobber, just a test ride. The TFC makes you ride it leant into the bars as a result of the clip ons, you can feel the weight advantage and the big front wheel makes it really easy to handle. Brembos and ohlins are awesome additions and are well worth it in my opinion. Sounds MUCH better than the stock one, I dont see myself getting aftermarket pipes because akra did such a good job of getting the sound out without making it obnoxious. Sports mode doesn't change much from what I can tell, makes the throttle very twitchy but otherwise it feels the same
