Lots of people complain of this, but frankly when was the last time you had a flat. I know I'm probably jinxing myself now but I've been riding my DR, my wife her DR, my Scrambler, and now the Tiger for almost 10 years and the only time I'm changing a tube is at tire change time. I still carry spare tubes, irons etc. but have yet to need them. I just don't worry about it anymore.
