backrest removal problem

[RussRushX2]

I'm trying to remove the passenger back of my 2018 XL883N.
Nuts are heavily corroded, too stubborn they wouldn't even budge with penetrating oil and wrenches.
I'm thinking the rear suspension will give me more room to work.
Anyone got tips?

I've been there, those corroded nuts are brutal. Try heating them gently with a torch, then hit em with more penetrating oil

As @Merlin21 said, hit it with a torch and get the breaker bar, it's a winning combination
