Melted my saddlebag today while doing groceries (lemmy.ca)

Ya that's brown rice falling out. These bags were supposedly designed for sport bikes with upright facing exhausts and apparently are specially lined to be heat resistant and able to sit in front of the exhaust.

Came home from a grocery run to find that my frozen salmon fillets were fully thawed, my sweet potatoes transformed into baked potatoes, my cinnamon sticks became charcoal, and my rice bag melted 🙃

I've done groceries maybe a dozen times with these bags without issue but I guess the bag got a little too close to the exhaust. I spent all day today scraping dried molten plastic off my exhaust pipes and trying to pull rice out of my exhaust baffles (only got 2 grains out 😣).

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.

    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.

    Done the things in your box get quite hot here on the right hand side?

    If it does I haven’t noticed it. I just took a 3 hour ride and popped the box off no problem, unless it cooled within the few minutes. I did also have wet clothes in that bag during the ride and they’re still wet, so if there’s any extra heat hitting it it’s a negligible amount.

    Maybe it was misfiring today

    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.
