If you look up various people mtors you can find their KV ratings. My old LRP X11 7.5t was a 4600kv motor, the current X12 7.5t is 4700kv. So I figured the Mamba 4700kv was close to 7.5t
However the Losi 6.5t is a 4880kv motor, so it show that different manufacturers have wildly different kV ratings.
As a rough guide though
7.5t is 4000-5000kv
6.5t is 5000-6000kv
5.5t is 6000-7000kv
But this is very rough. Generally Losi motors have rather low kV's, Novaks very high.
