What is Lambroken?
1.
Lambretta scooter that will run just fine on your own about town, but will soft seize, break a cable or have some other debilitating problem the moment you either ride with a group of Vespa scooters or get an inconvenient distance out of town.
Vepsa Rider A "What happened to the Mod?"
Vespa Rider B "His Lambroken couldn't make it, so we left him."
Vespa Rider A "You couldn't bring him two-up?"
Vespa Rider B "He said he'd rather push his Lambretta than ride a Vespa, so we decided to let him do just that."
