Z400 2023 vs Z500 2026

If straight-line speed is your priority, the Z500 takes the lead. With 6 HP more than the Z400, it offers a more spirited ride that will be noticeable on highway overtakes or track days. Both bikes share a similar footprint on the scale, with only a negligible 1kg difference between them, so handling characteristics will depend more on center-of-gravity than raw weight. Bottom Line: While both are capable, the z500 offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
