Best for: Designed as a lightweight sport-styled commuter and learner bike rather than an outright performance machine.
Built for: A nimble, sharp-handling small sportbike that rewards revving the little single and flicking it through corners rather than relying on outright power.
Not ideal for: Not suitable for riders wanting real highway speed, long-distance touring comfort, or off-road capability.
