I have the 2017 Indian Roadmaster and I have extreme upper back pain from leaning too far forward. I have installed the drivers back rest and had the dealership install the 2"inch pull back handlebars and still have back pain. I have also tried the Helibars on my 2016 Roadmaster (traded in for 2017 RM) and returned them because there was no additional pullback from their bars compared to Indians pull back bars, although you could adjust the angle of your hand/wrist with the Helibars. Other things I have tried is putting a longer bolt in the drivers seat rest that pushes you more forward. I can get a little closer to the handlebars, but then I have a sore back and sore butt, because you are almost sitting on the horn of the saddle. I am 5'6" and from my armpit to my longest finger I measure only 23". I had the back problem in 2015 when I bought my first motorcycle which was a 2003 Kawasaki Vulcan 800. After riding for a long distance I discovered my back would hurt. I researched my back problem and came to the conclusion I needed risers for my handlebars. I purchased 7 inch riser with 2" pullback and after the installation the pain went completely away. Well, with the Roadmaster I cannot put risers on because of the batwing fairing. The 2 inch pullback handlebars do not put the handlebars close enough to me and they need to a be a little higher also. I wanted to see if the mini-apes would help with the back pain, so I test drove one at Indian Motorcycle of PCB. Although the mini-apes put the handlebars higher up, they widened the grip which forced me to lean forward once again. Didn't like the fact that the mini-apes put my hands in the air stream and not behind the batwing fairing, but if it relieved the back pain it would not have been an issue, but it didn't. I would like to know if anyone had figured out a way to alleviate upper back pain for someone of short stature.
