How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built primarily for mixed on- and off-road adventure riding, with real dirt capability rather than just cosmetic ADV styling.
- Built for
- A lightweight, single-cylinder adventure bike that rewards playful, momentum-based riding over outright speed, feeling nimble on trails and eager to change direction.
- Not ideal for
- Not the right choice for riders seeking high-speed touring comfort, large-capacity torque, or a plush ride for two-up long-distance travel.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
