Does MZ scooter have a 150cc model? From what I've seen there's only a MZ 125, correct me if I'm wrong.

Scooters are definately not as durable compare to the cub-chai due to the fact of the auto gearbox. You don't whack it as the repairs will prove costly, use sparingly with a gentle concept & follow the maintainence schedule to minimise costly repairs to the gearbox.

MZ125 is okay for the occational runaround as it's lighter & easily maneuverable compared to the other scooters, off course a bit tight with passenger.
