If straight-line speed is your priority, the Street Triple 765 RS takes the lead. With 7 HP more than the 990 Duke, 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 990 Duke. Its seat height is 11mm lower than the Street Triple 765 RS, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: It's a close call. Choose the 990duke if you prefer its specific styling and ergonomics, or the street-triple765 if you want the alternative brand character.
