From the facebook event page:

Motorcycle Mondays is on the move in 2023. Our new home is an old favorite, O’Donovan’s Pub at 2100 W Irving Park Road in Chicago. On August 7th, we salute the Motorcycles from Italy. Ride-In on a Italian Motorcycle from 6pm – 9pm and receive a FREE Motorcycle Mondays Jacket Patch. The BEST bike takes home the Motorcycle of the Month Trophy! See You There!

So they didn’t expressly invite scooters, but hey… what’s more Italian than a Vespa? All are welcome, but they’ll probably ask non-italian bikes to park down the street. They might ask ALL scooters to park down the street. We might win awards, or we might end up in a street fight. We’ll see!
