I trimmed down the weight in my pack last year based off what I know other riders carry. Still stuff my large burandt bag full, plus the dash compartment and a handlebar bag
I carry less tools now, only a few fairly universal tools to help limp stuff out. Crescents, pliers, screwdrivers. Plus zip ties, pull tape, and gorilla tape.
I carry lots of gloves. 2 light pairs and 2 heavy pairs. I swap my gloves out a lot depending on temp or conditions.
Usually have 3 or 4 spare goggles with me too but this year I'm going to get one set with quick-change lenses so I can just carry spare lenses instead of entire goggle sets.
I keep a basic first aid kit, which I had to use for the first time last year.
Foldable saw, which I use a lot...
Bivvy, Firestarters, lighter, matches. My dad carries more survival supplies and my wife has a big bag of protein bars she keeps in her tunnel bag for emergency food.
Probably a few other things I forgot.
Now... my Father-in-law down in Colorado carries a lot. Like, A LOT. He has this huge waterproof bag full of stuff, honestly probably 60-70lbs, full of over-the top survival gear. You'd think he's packing to go out in the Alaskan bush for a week. I've seen him strap snowshoes on top too. His shovel is a big Murdoch's grain shovel. He also has one of those powder jacks strapped to the side of his tunnel, and you need it to get that damn thing out of a hole.
