Despite what many will and have said, if done right, lowering your ride with proper suspension can give great results. Remember the Ultra Classic Low and Ultra Low from a few years back? They used the H-D profile low shocks front and rear (1" lower all around).

I'm a bit height challenged and wanted to get "flat-footed" on my King. I have 12" shocks in back and a lowering kit up front. The 12" rear shocks have a 3 1/4" travel and with proper sag, will sit about 11 1/4" when sitting on the bike. I don't carve canyon roads, but I enjoy the twisties as much as anybody and have no issues. The rear shocks I have are by Ohlins and are a great set of shocks for me.

I've also had my seat modified to get and extra 1 1/2" lower as well. That combo gets me flat-footed with a slight knee bend.

 

I guess I need to make a video,LOL
