Question about an extremely slight wobble

Slight wobble showed up, only appeared around 30mph, and only with a passenger. no wobble discernable at all without a passenger, or faster or slower.

is this a symptom of something I should be concerned about? and if so, what should I be checking?

2019 Husqvarna svarpilen 401 (same engine, nearby the same frame as KTM 390).

thanks y'all!
