Motorola loves to lock down their devices tight! This makes developing Roms and Mods for their devices a difficult task, but that isn't keeping developers "Dhacker29" or "Hashcode" away from these devices. In fact they have just released their build of AOKP JB MR1.1 to several devices. Those devices include the Droid RAZR, Droid4, Droid3, and the trusty Droid Bionic. The latest release is KEXEC based so you will be able to flash this over any stock system! Hashcode and Dhacker have worked together to get the KEXEC working nicely. You will need to install this using SafeStrap 3.11 or higher. If you are not familiar with SafeStrap you can check out Hashcode's How To SafeStrap Post.
AOKP is a great rom and it is great to see it on these devices. Android Open Kang Project is based on Android 4.2.2 and includes Rom Control which is filled with enough customization options to keep you busy customizing your device for at least an hour. You get options like custom carrier logo, battery, clock, nav bar options, lockscreen options, power menu settings, new navigation ring settings, quick settings tiles options, and more! Not to mention this is a buttery smooth Rom with tons of tweaks for performance and improved battery life. Check out the source links below for the downloads.
