If you give some strain relief to the connector by providing extra cable looped towards the motor and zip-tied, that should be a reliable fix for you.
Imagine though if you did solder the wire and the motor then failed, now not only do you have to replace the motor, but also the cable.

I did FTC in 2009 and noticed that even with a zip tie holding the wires onto the motor, the connectors are incredibly loose (they came that way) and tend to fall off. Pinching them a little smaller and using a strain relief would work though. Soldering works too (you can desolder of the motor fails). Just a matter of preference.
