How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- A street-biased supermoto built for punchy, playful riding through urban streets and twisty backroads with occasional light off-road use.
- Built for
- Nimble, single-cylinder torquey character that rewards aggressive, flickable riding rather than outright top-speed pursuits.
- Not ideal for
- Not ideal for riders seeking long-distance touring comfort, high-speed stability, or a low, easy-reach seat height.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
