The two bikes are close enough that posture preference matters more than the overall score.
Rider fit: reaching the ground
The BMW R 18 Classic has a 710 mm seat; the Harley-Davidson Street Glide Limited sits at 699 mm — a 11 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 71 cm for the BMW R 18 Classic and 70 cm for the Harley-Davidson Street Glide Limited.
That makes the Harley-Davidson Street Glide Limited the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the BMW R 18 Classic 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.
