How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A dual-sport trail/enduro machine built for exploring dirt roads, light off-road trails and cheap commuting, not highway mile-crunching.
- Built for
- Playful, frugal and adventurous little thumper. Rev-happy 155cc single that thrives on trails, dirt tracks and darting through traffic.
- Not ideal for
- Not for highway touring, two-up trips or speed seekers; the modest power, small tank and firm seat make long fast rides tiresome.
