My Shad 50l will hold 2 full face helmets w/o problems but some things will Not fit due to shape differences. Shad currently makes the Yamaha “factory” box’s. I use my topbox all the time but I am very aware of any weight added to it because of the broken subframe I had.
I will also say that adding a “stiffy” kit will not prevent a broken subframe but will keep the broken piece’s from littering the highway behind you. I will also add that in my opinion adding the Yamaha heavy aluminum rack, the givi sr357 or the Shad tubular rack is not a 100% garantee either, it is really just a very poor design.
That said, I will say that only the Yamaha heavy aluminum rack, the givi sr 357 orthe Shad tube rack are the only things that give you any chance of not breaking the subframe. I used the “stiffy kit” that I had installed when my subframe broke as the base for additional support that I heavily modified in addition to the Yamaha aluminum rack. I will add that if your top case flops or shakes around it is at risk of breaking the subframe due to the vibration transmitted to the subframe through the unsupported tab on the topframe that hangs out in the wind and everything pretty much attach’s To.

But add the givi sr357, the. Shad tube rack or The Yamaha heavy aluminum rack and the chances of breaking your subframe are then pretty slim but you still need to be aware of any weight added. My top box does not move or flop at all now but I still adhere to the 10/11 lb max load even though with the mods I added it would probably allow me to ride in it w/o breaking things. Just be aware that it is a frail design.
One thing I would add is that my neighbors 2017 Harley Ultra Limited’s top box has a very large “10lbs max weight” inside of it although it’s big enough to carry 2 cases of beer along with ice and a drain in the bottom neatly Routed to not make a mess. Has anyone heard of a Harley breaking a subframe ? My buddies 2015 r1200rs beemer has the same warning.
