If straight-line speed is your priority, the Z900 takes the lead. With 30 HP more than the GSX-S950, 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 2kg difference between them, so handling characteristics will depend more on center-of-gravity than raw weight. Bottom Line: While both are capable, the z900 offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
