I've run a 32mm front bar for 2 yrs now. It has minumal effect on the on the ride. The FX3 works the same. Cornering however is flatter than ever if you can imagine that. It does introduce a small amount more of understeer, which allows you to compensate with the throttle. I like it very much. The whole theory of sway bars is to improve handling without adversely affecting ride.
