Best for: Built as a street-focused naked hooligan bike, it excels at spirited backroad blasts and canyon carving rather than long-distance cruising.
Built for: Raw, characterful, and aggressive, it delivers strong Ducati V-twin torque, sharp handling from its trellis frame, and an emotive desmodromic engine note.
Not ideal for: This is not the right bike for new riders seeking a gentle first bike or for anyone wanting genuine long-haul touring comfort or off-road capability.

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