Well yes, I mean he's embedded his body with lightning and only the yellow fash or people that are as fast ir faster than KCM Naruto whom is faster than lightning, can outspeed him so I mean
plus when sasuke was bout to hit itachi with kirin,he said something like he was gonna attack with an attack similar to itachis,thats too fast to evade,meaning almost lightning fast,and raikage dodged amaterasu,meaning his speed is up there
