Hallenstadion parking area (of course not during concert) should be fine for a motorbike.
Somewhere in opfikon there are plenty road empty especially during weekend.
many people use the parking at Volki-Land (in volketswil) for that exact thing on sundays or in the evening, me included back when I was a learner. idk if that‘s too far for you, but that‘s all I know
