How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's built as a small-displacement sport-styled commuter rather than a genuine performance machine, despite its racing-inspired name and fairings.
- Built for
- It has sporty styling with a windscreen and disc brakes front and rear, but the 50cc air-cooled engine limits it to modest, gentle performance.
- Not ideal for
- It is not suitable for highway travel, long-distance touring, carrying a passenger comfortably, or anyone seeking real speed or power.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
