How it rides
Editorial estimate from the spec sheet - not lab tested- 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.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
