Procedure

Download mfastboot-v2 extract its content and use that for unlocking Bootloader

Unlock your bootloader From Here

TIPs:

Unlocking bootloader will wipe your device, Backup your photos, music, contacts using applications in play store or whichvere method you prefer

The motorola site tells us to download the android SDK, You can skip that big download and use the fastboot in step 1

Follow the further steps given on motorola's site, After clicking on Request an Unlock Key, You will get an email which will consist guideline to proceed further!

Clicking on Request an Unlock Key is the point where you lose your warranty

Download The TWRP recovery from here(thread) or here(Goo.im) rename it recovery-twrp.img and move it in the same folder as of step 1

Download The SuperSU from here(thread) or here(chainfire.eu)() and copy it into the root of your internal memory!

Connect your phone to PC and Reboot to bootloader by pressing VolumeDown+Power button for about 6-7 seconds.

Go to the directory in step 1, Do Shift+RightClick in empty space in the folder without selecting anything, Select Open a command window here.

Run following command

fastboot boot recovery-twrp.img

If facing errors refer to TIP No. 2 and 3

[*]Now touch doesn't work in recovery straight away, so wait 60 seconds without touching the phone, The phone screen will go blank.

[*]Press power button and do swipe to unlock to get your touch working again!

As Motorola released source code for the kernel, [MENTION=4584140]cybojenix[/MENTION] has fixed the touch issue, you can skip to step 10 directly!

Select Install, scroll down and find the SuperSU Zip downloaded in step 4.

Swipe to confirm, wait untill the flash is complete and then select reboot, to boot into your phone which is rooted now

Check your app drawer, There should be SuperSU installed. Congratulations you are rooted!

TIPS:

Downloading things from the thread link is a better option as the hotlinks may get outdated, Thread links will not!

If you want to install twrp rather then just booting into it for once, you can use following command to flash it permanently

fastboot flash recovery recovery-twrp.img

If stuck on Boot Logo of Motorola (blue M), [MENTION=5084935]JerryGoyal[/MENTION] has provided a Thread Here to solve the problem using CWM instead of TWRP.

According to the method you can download CWM and Rename it to recovery-cwm.img in place of TWRP in step 3. Execute other steps the same

And in step 7 Replace the given code with

fastboot flash recovery recovery-cwm.img

In CWM Touch doesn't Work to scroll Use Volume Buttons and Use Power Button to select the choice

in Step 10 you would select Install from sdcard

If you do something wrong and stuck somewhere, The stock firmwares are available for restoring.
