That is quite a small motor. I would imagine the current drawn is very low. Probably under half an amp so I would not worry about suppression until you notice any interference.
A standard set of capacitors across the terminals would probably be in the PicoFarad range.

Hope this helps

My experience with small motors is that a 0.1uF ceramic disc capacitor across the two motor terminals generally fixes any RF problems.
