Z650RS 2025 vs Speed 400 2024

If straight-line speed is your priority, the Z650RS takes the lead. With 28 HP more than the Speed 400, it offers a more spirited ride that will be noticeable on highway overtakes or track days. When it comes to agility, the Speed 400 has a clear advantage. Weighing in 17kg less than the Z650RS, it will feel significantly easier to handle in low-speed traffic, parking maneuvers, and twisty corners. Riders with a shorter inseam should lean towards the Speed 400. Its seat height is 30mm lower than the Z650RS, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: While both are capable, the z650rs offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
