"I wish he still had the motorcycle"
He no longer has the motorcycle, but I wish he did. I'm not sure what verb tense I should use for tener.
"Deseo que él todavía tiene la motocicleta."
Is this right?
Deseo or espero are considered verbs of emotion or volition. The require that the verb in the subordinated clause be conjugated in the subjunctive mood.
"Deseo que él todavía tuviera la motocicleta.

Tener in the preterite, I think because as you've said that he had the motorbike but doesn't any more. The preterite is used to describe a completed accion/event.
Qfreed is correct. You would use the subjunctive....I think it would be past subjunctive- correct me once more if I'm wrong?
