The dimension I posted is the width across the bags, mounted. Yeah, they might squish a bit, but shipping companies will probably take a maximum dimension.
My mounts (without bags) are ~18", Mistral canisters ~23", bar-end weights ~29"
Ahh yes, the width of the "other stuff" ... I forgot that. I meant to say to remove the bags only and box 'em up and mail 'em, leave the mounts on the bike, but no matter. Not that much wider with the bags on.
Last bike I shipped, the truck/trailer opened up and it was FULL of huge Harley's. Little Goose with Teknos isn't near that in width.
