Designing a motorcycle that genuinely works as both a sport bike and a long-distance tourer is as hard as it sounds. Increase the comfort, and you often add bulk. Chase the performance, and the tractability suffers. Try to include everything, and the price tag can spiral well past the point of reason. For decades, manufacturers have approached this problem by doubling down on one side of the equation or the other, producing bikes that are either impressively fast or genuinely comfortable — rarely both, and almost never at a sensible price. Too many premium touring machines solve the problem by simply getting bigger, heavier, and more expensive. The result can be impressive, but also a little exhausting in the real world. That's why the Yamaha tourer in context dominates in this space.
