Best for: Designed for nimble urban riding, learner-friendly commuting, and playful short trips on tight, twisty roads rather than sustained high-speed travel.
Built for: A flickable, street-legal supermoto with sharp handling, road-biased 17-inch wheels, and just enough power to feel engaging without being intimidating.
Not ideal for: Not a good fit for riders wanting sustained motorway speeds, long-distance touring comfort, two-up riding, or serious off-road capability.
