Yeah, the Valk trunks seem to be crazy high [$500-$800] but it matches the styling lines of our bikes. Most of the trunks or topboxes seem to be made for Harley, matching their ugly sharp edged/angular saddlebags instead of our nice curving lines.
The other part of top boxes that concerns me is the hinge modification required to get the saddlebags open with a big trunk in the way. I'd rather move the trunk rearward or, better yet, have a narrow trunk that allows the saddlebags to open normally.
Currently, my crazy thought is taking two aftermarket saddlebags, mounting them together.
But for now, I'll just make do with my soft bag sitting on my trunk bracket.
