Vespa T5 wobble

I just got a 10 year old Vespa T5 150 in great condition. Runs great, but there is a recurrent disconcerting wobble at low speeds (25 - 35 mph) that is actually kind of scary. I am a relative novice scooter rider but have ridden other scooters (Stella, Honda) that do not do this at all. Any ideas about what might be causing this and what can be done about it?
