No, the car rides flat and follows the road surfaces. It absorbs really bad sections of road with big bumps without giving you that feeling of pogo out of control. The downside is that these large bumps get damped very quickly and the vertical deceleration is felt in the seat of your pants, so although the car feels very stable, your body ends up feeling the bump more.
Repeating expansion joints and undulations on the concrete freeways around here when going 75 mph are still not being dealt with as much as I would like. The chasis is mostly taking the hit on these instead of being absorbed by the suspension. It might have something to do with the firmer dampening on the HD's, because the springs dont seem to be any stiffer than stock.
