How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for supermoto-style thrills: flicking through tight corners and urban streets with sharp, aggressive handling rather than covering long distances in comfort.
- Built for
- A raw, mechanical, and characterful machine with big single-cylinder vibration and torque pulses that reward a rider who enjoys visceral, unfiltered feedback.
- Not ideal for
- Not a good fit for riders seeking plush comfort, pillion-friendly ergonomics, or a relaxed long-distance touring experience.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
