How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It is built primarily for enduro trails, technical off-road riding, and casual dirt exploration rather than speed or long-distance road travel.
- Built for
- It has a playful, nimble, momentum-based riding character typical of small-displacement air-cooled enduros, rewarding smooth throttle and body-english over raw power.
- Not ideal for
- This is not the right bike for riders wanting highway speeds, passenger comfort, or long-distance touring capability.
