look in the progressive tech section on thier website. I think no matter what size you order (12" or 12.5") the max compression on the 440's is 10.38". Don't hold me to that, but I know progressive has the info so that you can check your bike and see if it will bottom out.
I put 12.5s on mine and the only issue I had was the top of the shock hitting the belt guard when it compressed, I ended up getting spacers that are thicker than the ones you get with the shocks and all is well, never bottomed out the bike. Of course it could have had something to do with my fat arse having them set to soft.
