Yes, the one on the right 'looks' really wide partly because it is so short, the B17 "S" model.
It's actually 177mm wide, - too narrow for my sit bones. And the non-S model is 170mm.
The B68 as I said is 210mm wide and is the only saddle that actually fits my sit bones width-wise so I'm not riding literally on the saddle edges with my bones.
