Moto E Root 5.1

[JapeMoto]

Hello guys,

I hear about root for android 5.0, which does not need unlock bootloader. It exploits a vulnerability.
Is there anything for 5.1 and fits Moto E xt1021 ?
I needs root privileges only for app to transfer all applications into card SD.
Whether after all I have to unlock bootloader ? :'(
Do you know some automatically root for moto E xt1021 5.1lollipop ?

I know that I should look on google, but unfortunately poorly know English.
Thanks for the help.
