Best for
Built as a nimble, street-biased supermoto for flicking through city traffic and carving tight, twisty backroads rather than covering long distances or going off-road.
Built for
A playful, flickable little street hooligan that rewards aggressive cornering lines and quick direction changes over outright speed.
Not ideal for
Not a good fit for riders wanting highway touring comfort, serious off-road capability, or strong outright acceleration.

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