Mileage check - Need help!

Bought a brand new GT, been about 350 kms total, 20 days old. Filled the tank up to the brim, reset the trip A odo to do a mileage check, it’s showing 134 kms run with one bar blinking which is reserve. Have only ridden it in the city, not gone above 4K rpm as want to make sure I ride as per all the suggested parameters Shouldn’t the bike be giving 17-18 kmpl mileage or is this as expected? New to the RE club, and new to the world of motorcycling Let me know your two cents RE fam!
