with negligible damage. Do you think that Base Naruto would take that kick right to his jaw and still be alive? Or relatively uninjured? The kick was strong enough to cause some damage to the cliff after throwing Naruto back a few meters. The main thing to pay attention to, is that B has physical strength surpassing Ay, and he used his partial Bijuu transformation yet he still got thrown back with Naruto. That's how much force was in the kick.

Base Naruto obviously can't do that.
-KCM lets Naruto survive Tenpenchii (at the cost of the mode), and it lets him tank Madara's Katon. Base Naruto would be dead.

and SM together? What? :lol.
Oh wait, he's using RSM as he lacks pigmentation and his skin isn't glowing. RSM Naruto tanked Sasuke's Chidori at the valley of the end, and yes it hit him as he was tossed back. No damage.
