Best for: Built for sharp, playful cornering and sporty commuting rather than outright speed, thanks to its featherweight chassis and small-capacity engine.
Built for: A miniature GP-styled sportbike that rewards revving the engine hard and flicking through corners rather than relying on raw power.
Not ideal for: Not suited to riders wanting strong highway overtaking power, long-distance touring comfort, or two-up riding.
