Best for: This is a supermoto-style machine built for playful, aggressive street and light off-road riding rather than long-distance travel or outright top speed.
Built for: It has the character of a nimble, high-strung supermoto hooligan bike, eager to wheelie, stoppie, and carve tight corners rather than cruise smoothly.
Not ideal for: It is not a good fit for riders wanting a comfortable highway tourer, a passenger-friendly bike, or a low-maintenance four-stroke commuter.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
