How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a sporty naked streetfighter, it's meant for spirited road riding, commuting with character, and weekend backroad fun rather than long-distance touring or racing.
- Built for
- The V2 engine and short exhaust give it a distinctive, torquey, slightly rough-and-ready personality that rewards riders who enjoy mechanical charisma over refined smoothness.
- Not ideal for
- It's not a good fit for off-road riders, those seeking cutting-edge performance, or riders wanting a comfortable long-haul touring platform with wind protection and luggage capacity.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
