First bike I had with lowers was a '96 Ultra Glide. Liked them so much, I decided to try them on my '05 Electra Glide Classic, Took them off the next day and unless it starts snowing or raining every day here I have absolutely no intention of ever going back to them. Why? Because of the heat build up. I'm in Hawaii and quite often ride with shorts and slippers. The lowers change the way air circulates around the engine, not too noticeable at highway speeds but shear misery in traffic or at slower speeds. Even with jeans on the heat build up was really uncomfortable to ride in. All the lowers seemed to do anyways was slow down the rate my legs got wet at when it rained.
