Capacity of the seat structure?

528 Views 7 Replies 5 Participants Last post by  Wavshrdr
Wondering if anyone has seen any specs on how much weight you can put on there?

Imagining and extension with a hardcase mount. Soft storage for the LWing seems wrong. I just don't want to always have 2 bags and all my gear. Probably fine with the tank bag though it is starting to show wear on the plastic covers.

Would really just rather have a hard case past pillion seat with the option to add a soft bag on the pillon seat. Figure I need and extension but not sure if I need supports down to the passenger pegs or if the seat mast can handle that level of weight and leverage.

Specifically curious what you thing Ben. Thanks again.

I’ve run bags of all types with my seat and there’s not an issue. The seat frame is cast aluminum and is designed as a cantilever to the subframe - it’s quite sturdy. Consider that the seat can easily hold two adults and not have an issue - adding hard/soft bags will not hurt it. In most cases, when it comes to load, it’s always best to engineer for MORE than what the average user would do.

You have up to 400lbs to play with on the seat - more than enough for a typical rider, gear, and luggage.

Sure In was thinking leverage though. Assume a mechanical extension on that frame or behind the passenger seat. At 40-50lbs of frame, case and stuff. Just becomes a long structure and that point.

There is literally know way of knowing that without a spec, a model for FEA analysis, or actually breaking one to find out. So other than the spec giving, you're not going to find anything most likely. You can make some assumptions on mounting center point, and 400lbs at senter of seat, and use that to calculate a torque limit. But my guess is unless.youre putting an 8ft extension on, 400lb is fine at any reasonable loading.
I think every bike I have owned has said very similar max loads. ~400lbs max capacity rider/passenger and luggage. From my KLR 650 401lbs to my 2004 Vulcan 2000 412lbs. Even my 3 Wheeled Spyder RTS claimed to only support 440lbs.
Yeah totally. I was just wonder if I had some build an attachment to the seat mast to add a top box if I would need it to attach to the rear pegs to not take the weight of it, the box, and the cargo off the capacity. I guess it also changes the balance of the bike rearward.
Easy enough to play it safe and run a small strap to add extra support.
