Z650 2025 vs GSX-8S 2024

If straight-line speed is your priority, the GSX-8S takes the lead. With 15 HP more than the Z650, it offers a more spirited ride that will be noticeable on highway overtakes or track days. When it comes to agility, the Z650 has a clear advantage. Weighing in 14kg less than the GSX-8S, 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 Z650. Its seat height is 20mm lower than the GSX-8S, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: While both are capable, the gsx8 offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
