How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built primarily for light trail riding, commuting on rough roads, and general low-speed utility rather than speed or long-distance comfort.
- Built for
- A simple, low-powered air-cooled single that favors mechanical simplicity, easy maintenance, and off-road capability over refinement or outright performance.
- Not ideal for
- Not suitable for riders wanting highway touring speeds, sustained high-speed stability, or a plush, long-distance comfort experience.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
