How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a road-focused supermoto, this bike is meant for flicking through tight city streets and attacking twisty backroads rather than long-distance cruising or serious off-road work.
- Built for
- It suits a playful, corner-hungry rider who values sharp steering, sporty street handling, and a punchy single-cylinder engine over outright top speed or plush comfort.
- Not ideal for
- It is not a good match for riders seeking a relaxed touring companion, heavy passenger carrying capability, or a highly capable off-road adventure machine.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
