Best for: Built for stripped-down, stylish street cruising rather than outright speed or long-distance touring.
Built for: A bare-bones, blacked-out bobber persona with a big air-cooled V-twin rumble, favoring attitude and torque over refinement or high-speed thrills.
Not ideal for: Not ideal for riders wanting sharp cornering agility, sport-level acceleration, or serious off-road or highway touring comfort.
