Best for: Built primarily for spirited canyon carving and track days, with razor-sharp handling as its main selling point over outright straight-line power.
Built for: A revvy, precise, and eager middleweight that rewards riders who like to work the gearbox and chase the tach needle through corners.
Not ideal for: Not a good fit for new riders, anyone prioritizing all-day comfort, or those planning to load it up with luggage and a passenger for long-distance touring.
