Thank you for the response.

By the way, the meaning of 
motor_vehicle=no + motor_car=yes is an all encompassing restriction for vehicles (including bicycles, HGVs, trucks and buses) except cars, not just motorcycles.

If you're specifically restrictict just "2W" vehicles, the tag is actually motorcycle=no.
