If straight-line speed is your priority, the GSX-8S takes the lead. With 10 HP more than the SV650X, 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. Riders with a shorter inseam should lean towards the SV650X. 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.
