Best for: Built for long-haul two-up touring in maximum comfort, hauling gear in its trunk and top box across highways and open roads.
Built for: A rolling luxury lounge - stable, planted, torque-rich and unhurried, delivering effortless mile-munching with no need to balance or put a foot down.
Not ideal for: Not for anyone chasing agility, canyon carving, track days, tight city filtering, or off-road use; it steers like a car, not a motorcycle.
