Lol the saddle bag melting should be the least of your worries. You're coating the bag and everything inside of it with cancer causing chemicals. Even if it didnt melt you'd be eating straight cancer for dinner
What, you're telling me that exhaust flavoured food might have health concerns???
I tossed everything in that bag. Not very interested in some specially seasoned salmon, sweet potato, and rice 😁
Here's the sweet potato:

After finally being able to watch the video, I'd never expect a material bag to tolerate that - it's directly in-line with the exhaust and even slightly above it.
Even if the bottom of the bag were an aluminum plate, I think that plate would simply transfer heat into the bag.
It would require something like a lower plate, an air gap, and another plate, to ensure a heat break.
Or a plate on the exhaust directing the output more horizontally for the length of the bag.
Also, sorry this happened, that's a bunch of crap from the manufacturer.
Ya when I first received them I was super skeptical. Like no matter what, these bags on any sport bike with upwards facing exhaust will be in direct line of sight from exhaust gas. Zero issues all last year but my very first grocery run this year everything went to shit.
These were purchased from a motorcycling store and made by a company who makes saddlebags for motorcycles so I put my trust in that. Evidently, I shouldn't have.
Possibly too much weight made the bags sag just enough to be in the exhaust's line of fire.
Well that sucks. I'm trying to remember where my saddlebags drape, but they're definitely not in any possible line with the exhaust vent, nor are touching. I think my actual panniers made for the bike have a metal shield that sits between the exhaust and the pannier sort of hovers over and to the side of the exhaust.
Maybe your exhaust is just super special in how much heat it throws out.
It's a stock Honda 500cc so I wouldn't consider it super special
I have an NX500 myself, to be honest I went with some hard mounts that replace the passenger grab bars and hard boxes from Ali express, even with tarrifs (I’m in the US) the total was sub $500 for two boxes and a rack. Super worth it, I put it through hell and high water and they’re great. Definitely something I’d recommend.

Done the things in your box get quite hot here on the right hand side?
Ayy the adventure version of my bike! Love the white and black combo. Those cases look awesome. Something on rails like yours is what I'll have to get if I want saddle bags. I might just look into a tail bag in the interim. Does the bottom of the right box ever get warm?
I wanna wrap it in something like baby blue personally lol. And yeah, I’d recommend the cheap ones on Aliexpress personally, it’s like a quarter of anything else price wise. It doesn’t line up perfectly but I’m a function over form person lol. And I’m sure it does but I’ll have to check next long ride, but I’ve never had issues with anything melting or anything getting too warm
Baby blue would look cool too! My bikes boring and matte black. Are the mounts from AliExpress too?
Matte black still looks great in my opinion!
And Yep! Hopefully links are allowed but these are what I got

Seeing one of the reviews did remind me you’ll need someone with a 3d printer. The plastic spacer bit the bracket came with may as well have been made from tissue paper, but after printing new spacers they’ve been rock solid for me.
Oh excellent! I have a nice 3D printer so not a problem here. Thanks for the links and info!
For sure! Keep the rubber side down amigo. The Honda 500s are phenomenal bikes, definitely sucks about the melted bag though lol.
Maybe it was misfiring today
It's a year old lol it better not be.
Misfiring generally produces lower temps as fuel isn't fully combusted.
Even then, those temps will still melt nylon that's pretty close.
I suspect the manufacturer's claims are bogus, or at least poorly written and they actually mean they can tolerate the heat radiating from the muffler, not the direct exhaust.
Anything in line of the exhaust will melt over time from the long duration of exposure.
That looks like it was sitting on the exhaust?
It wasn't when I left the grocery store 😅 but I guess it sagged over the course of the half hour ride back home.
I don't think any bag can tolerate the heat of exhaust.
When moving on the road, it gets pretty hot - even rigid bags would sag
