The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The Beta Motor 390 RS Special Edition has a 950 mm seat; the Yamaha TT600RE sits at 945 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 95 cm for the Beta Motor 390 RS Special Edition and 95 cm for the Yamaha TT600RE.
That makes the Yamaha TT600RE the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Beta Motor 390 RS Special Edition 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.
