QJ Motor SRV 550 vs Triumph Rocket 3 Storm R ergonomics

Rider fit: reaching the ground

The QJ Motor SRV 550 has a 785 mm seat; the Triumph Rocket 3 Storm R sits at 773 mm — a 12 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 QJ Motor SRV 550 and 77 cm for the Triumph Rocket 3 Storm R.

That makes the Triumph Rocket 3 Storm R the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the QJ Motor SRV 550 gives taller riders more legroom and a more open knee bend.
