If straight-line speed is your priority, the SV650X takes the lead. With 28 HP more than the Z400, it offers a more spirited ride that will be noticeable on highway overtakes or track days. When it comes to agility, the Z400 has a clear advantage. Weighing in 33kg less than the SV650X, it will feel significantly easier to handle in low-speed traffic, parking maneuvers, and twisty corners. Bottom Line: While both are capable, the sv650 offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
