I'm running 11.5 in the rear and stock height in the front, only because the mechanic wants $350 to install the progressive springs and lowering kit sitting in my garage and I don't feel like tackling it just yet.
Anyway.
The bike feels a little different, but you get used to it very quickly. It's a little more difficult to be aggressive in corners, but that's fine because with the 11.5's on the back you don't want to be, things start hitting the pavement in a hurry if you get froggy.
I have forwards on mine (because I'm not a midget), and I think the Max looks great slammed. Pull the bars back a little bit and you're in cruiser land, albeit toting a giant can of whup-ass. Just dial yourself back a bit in the woolies.
