Bigger contact patch? I’m going to have to say no on that one. In fact, your contact patch increases as you lean over. And it’s not about stability, it’s about being able to carry more speed through a corner by effectively increasing the lean angle of the bike/rider combination (by lowering the center of mass relative to the corner center) beyond what you could otherwise do because you’d be dragging hard parts. Not something for public roads. Others (who are most likely well beyond the speed limit) may disagree.
