How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It's designed primarily as an economical commuter and light sport-styled runabout rather than a genuine performance machine.
- Built for
- Expect modest, unhurried performance from the 125cc air-cooled twin, with the drum rear brake and simple suspension reflecting its budget-friendly, old-school engineering.
- Not ideal for
- This bike is not suited to riders wanting highway touring comfort, high-speed capability, or serious off-road ambition.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
