How long do you ride before becoming tired?
Waiting on the OP to answer before I chime in.
Looks like I'm being called out.
Fine.
I find the stock seat on the 1300 to be adequate, if not superior, and that's my main focus for weak points. I've had numbness in my throttle wrist for years, and I have used the ThrottleMeister (discontinued, sadly) with great success in the past... wrist rests, not so much. I actually have sourced a used TM here in our very own For Sale basement, but haven't installed it yet.
(It's important to leave some things undone, so
@Obo will have something to remind me about.
) I will swap my left hand to the throttle side for very short durations when on the interstate (where the numbness typically occurs), as unwise as we know that to be. And yes, I have bumped the engine cutoff switch a handful of times. Not a ride-stopper.
Don't see a Russell DL saddle in my near future, that would most likely be da bomb. I've never owned one, but there are more affordable saddles that would provide a noticeable improvement, as well. I just stand up, when shifting positions still leaves my bum uncomfortable after a few hundred miles.
The McCruise is likewise inviting me, but that can wait, since my as-yet-unseen 1250 GSA has cruise included on it.
I've come within 50 miles of a SaddleSore on the 1300, but I have a couple / three SS1Ks already, and even though I had 3 or 4 hours left, I was tired and didn't feel like I needed another. Got lazy, actually - now I wish I had put in another hour and a half; would have had an easy cert. I rationalized, telling myself I didn't have to prove anything to anyone.
That said, I am well aware that many in the riding community view endurance rides with disdain, or even disgust. I recognize that I'll never be riding my best after 20-plus hours in the saddle. But it doesn't have to be a recipe for tragic results, either.
Now to the question at hand... 400 miles is usually easy, but heat makes it harder for me in the South, as well as my mindset; i.e., did I start out with a plan to do a long day? What is the destination? Is this for fun or for work? Will I be riding through rain? So many questions to answer the question, so I'll say for clarity and authoritatively -- it all depends.
I don't have any physical issues like arthritis, neck or back surgery, bad hips or knees... so I can ride without undue issues, if I'm rested and especially if it's somewhere I want to go.
So there ya have my "answer", which in characteristic fashion is not much of an answer at all.
Primarily, I just wanted to learn what some of you would say. I know some here are older than me, and have had joint issues and spinal / cervical issues.
Thanks to those who have shared about this here.
