Got the Progressive lowering kit with the 412 shocks installed on "Vicious" the other day. Following are the after shots.

The ride is not bad at all. In fact, the vibrations usually felt in the seat are absent. Sitting up straighter causes the shock of the hard bumps to be transmitted right into the spine however... handling does not seem to be better or worse to me.

Riding two up on the lowest shock setting did not cause any bottoming out. I run about 190lbs and Erin is a lot less than that!

Above you can see the lean "Vicious" still has on it's side stand.

Love the look of the fat tire unabated by the license plate hanging down over it. The lower sitting rear end makes it look even fatter.

Had to remove the fork bag as it used to occasionally rub the front fender and now it would definitely be rubbing it. You can see the left over fork travel capabilities here as well. Check out the light covers.
