Yeah, I've had the geometry on mine pretty aggressive- lowered GSXR front, Ohlins rear at full length, and JHS shorter dogbones- and the only time it flapped was when I'd messed up the suspension settings. I did get that one big lock-to-lock slapper but that was a combination of terrible suspension setup (I'd given it far too much rebound damping) and ridign a bit too hard on a very bumpy road- the rear shock started packing, and kicked off a big front/rear wobble, which in turn weighted and unweighted the front wheel. Not nice- but it took a lot of work to get the suspension that bad
