BMW R 1200 RT vs Norton Motorcycles Commando 850 Interstate Mk3 ergonomics

Rider fit: reaching the ground

The BMW R 1200 RT has a 820 mm seat; the Norton Motorcycles Commando 850 Interstate Mk3 sits at 838 mm — a 18 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 82 cm for the BMW R 1200 RT and 84 cm for the Norton Motorcycles Commando 850 Interstate Mk3.

That makes the BMW R 1200 RT the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Norton Motorcycles Commando 850 Interstate Mk3 gives taller riders more legroom and a more open knee bend.
