Bottoming out suspension
I ride a 2003 chopper and have never had a problem with it bottoming out, even two-up. However, I do find that the suspension doesn't work well above 70mph. It just doesn't recover quickly enough and it starts bouncing around. Now, I rarely ride above that speed anyway, but it would be nice if it smoothed out like most bikes to allow faster top speeds, particularly on open roads. My last bike was a lowered HD softail custom that had been heavily modified and, even it rode much better than my BDM. You're riding a hotrod after all so you can't expect a smooth ride. Like they say, "you can be cool, or comfortable." Sounds like you've made your choice.
