I have an 1199 and I prefer using my Sequence shirt, which has a wide velcro attached kidney belt, instead of a jacket, even though the jacket has better abrasion resistance. The main reason is that in the tuck it helps support my abdominal muscles, lessening fatigue, and my back feels much better after a long ride. If you are not wearing a kidney belt, especially a wide one, I think you are missing out on a very useful piece of kit for your ride. Having it integral with your jacket or body armor is a big plus. Good tank grips, as well as a tank spacer, are also a great idea to help hold you in the saddle and reduce your back and abdominal stress.
