How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Designed primarily as an urban commuter and playful street bike with supermoto styling rather than a genuine performance or off-road machine.
- Built for
- A nimble, upright, tall-stanced small-bore machine that rewards flickable low-speed handling and city maneuverability over outright speed.
- Not ideal for
- Not a good fit for riders wanting sustained highway touring, two-up comfort, or serious off-road capability given its limited power and street-biased suspension travel.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
