Best for: Built for flickable, playful riding through tight urban streets and twisty backroads rather than outright speed.
Built for: A nimble, tall-stanced street enduro-styled motard that rewards aggressive lean angles and quick direction changes over straight-line power.
Not ideal for: Not suited for riders wanting sustained highway speeds, long-distance comfort, or carrying a passenger any real distance.
