These are 7.5"x14.5"x17.5" 20mm (I think) cans on my wife's Versys mounted on a SW-Motech Evo-rack with the Happy Trails pucks:
She has dropped the bike loaded and unloaded numerous times with the ammo cans mounted. The ammo boxes are incredible sturdy, almost indestructible. The SW-Motech racks actually bent at one of her get-offs and the ammo cans had just scratches and a very small ding. Biggest drawback is there weight: a whopping 20 lbs each! Aluminium boxes the same size weigh in at about 11 or 12 lbs I think
but cost a lot more.
To shed weight i started redesigning the boxes and ended up cutting off about 6 lbs:
Ended up with this:
Added hinges in the back and lockable, keyed-alike draw latches.
They just need some final touches and a satin-black paint job and they are ready to go. Once they are painted they will look the part.
Just started converting a set for my Terra. I think 14 lbs each is a manageable weight for some sturdy sidecases?
Outfitting ones bike with luggage is a very personal thing. I really don't want to spend/don't have $1000 ore more on a luggage system for my hobby.
