How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- This is a purpose-built 1980s enduro machine designed for trails, motocross-style tracks, and rough terrain rather than paved commuting.
- Built for
- A raw, buzzy two-stroke single with an old-school enduro character that rewards momentum, throttle finesse, and a willingness to get dirty.
- Not ideal for
- Not a good fit for riders wanting a comfortable, stable highway tourer or a modern rider seeking strong braking performance and passenger accommodation.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
