How much heavier will the Yamaha Seca be than its dry weight?
Do not treat dry weight as curb weight. Adding the listed fuel capacity alone produces roughly 539.5 lb (244.7 kg); the true ready-to-ride figure can still differ because dry-weight definitions vary.
What is the Yamaha Seca full-tank weight estimate?
Using the listed dry weight plus the calculated fuel mass, the estimated weight with a full tank is 539.5 lb (244.7 kg). That still may not equal official curb weight because dry-weight definitions can exclude other fluids or equipment.

Is the Yamaha Seca easy to move around by hand?
Yes, the mass is substantial enough to matter at walking speed. Parking direction, slope and secure footing become important because recovering the bike from a lean takes more effort.
Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition.
