Engine architecture and displacement
390 Duke lists 373 cc, 43 hp and 37 Nm; Ninja 500 lists 451 cc, 51.3 hp and 42.6 Nm. Output figures are compared on paper only; gearing and test methods are not normalized here.

City maneuverability
For city-use planning, the recorded differences are price, curb weight, seat height, tank size and braking equipment. 390 Duke is lighter on paper, while 390 Duke has the lower observed starting price. Those facts can inform a choice without claiming one motorcycle is universally easier in traffic.
Longer-ride considerations
Ninja 500 has the larger published fuel tank. Tank size, published economy and ground clearance can help trip planning, but MotoIndex does not infer long-distance comfort from specifications alone.
