V speeds depend on many things. Weight, flap setting, runway length, density altitude, obstacles. A loaded 321 on a 3 hour flight has extremely high V speeds. 170 plus knots is very common. I haven't flown a 737-900 but I would guess their V speeds are high as well, but maybe not that high.
I am not sure I ever saw 145 knots for Vr on a 321. Maybe a ferry flight.
