How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a dedicated enduro and trail bike, it excels at technical off-road riding, motocross-style tracks, and rugged terrain rather than pavement cruising.
- Built for
- Light, nimble, and torquey, this air-cooled single feels raw and mechanical, delivering direct feedback and confidence-inspiring agility over rough ground.
- Not ideal for
- This is not the right choice for riders seeking highway comfort, high top speed, passenger touring, or a low, easy-reach seat height.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
