Best for: Built as a nimble, corner-carving supermoto for tight roads, urban blasts, and playful track days rather than outright top-speed performance.
Built for: A cheeky, flickable street weapon that thrives on throttle-happy, aggressive riding through twisty and urban environments.
Not ideal for: Not a good fit for riders wanting relaxed long-distance touring, pillion comfort, or high-speed motorway cruising.
