Monster SP 2024 vs 990 Duke 2026

If straight-line speed is your priority, the 990 Duke takes the lead. With 10 HP more than the Monster SP, 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 4kg 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 990 Duke. Its seat height is 15mm lower than the Monster SP, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: It's a close call. Choose the monster if you prefer its specific styling and ergonomics, or the 990duke if you want the alternative brand character.
