you have gotten some wonderful buys on the 440's and 418's best i remember - person does need to be careful though - twice now on ebay I've seen 440's listed because that was what is on the box - but what was in the box was really 412's - after some convince'n via pictures and descriptions I got them both to relist the shocks as 412's.
back to original question there are down sides to shocks longer than 11-11.5" shocks - like the beltguard rubs, the kickstand is too short, oil level sight glass is incorrect unless you raise the front because you have changed the angle of the crankcase - all can be dealt with but just understand the whole picture before you go after long shocks
sorry forgot about an important one - you may also cut down on the range of the bike - as you lift the rear you also angle up the rear of the fuel tank - this causes fuel to move to the front of the tank and uncovers the reserve tube before the tank is empty.
