Best for: Built as a muscular power-cruiser, it delivers brutal straight-line acceleration and effortless overtaking rather than nimble cornering ability.
Built for: The Rocket III Roadster has a dominant, torque-drenched personality that rewards relaxed, throttle-driven riding over aggressive lean-angle attacks.
Not ideal for: This is not the right bike for new riders, tight urban commuting, or anyone seeking a light, flickable machine for twisty backroads.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
