Tuono 660 Factory 2023 vs Monster SP 2024

If straight-line speed is your priority, the Monster SP takes the lead. With 16 HP more than the Tuono 660 Factory, 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 3kg 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 Tuono 660 Factory. Its seat height is 20mm lower than the Monster SP, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: While both are capable, the monster offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
