The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Triumph Bonneville T120 Ace has a 785 mm seat; the Triumph Street Cup sits at 780 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 79 cm for the Triumph Bonneville T120 Ace and 78 cm for the Triumph Street Cup.
That makes the Triumph Street Cup the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Triumph Bonneville T120 Ace gives taller riders more legroom and a more open knee bend. Load your own height and inseam into the simulator to see exactly how each one fits you.
