I would not recommend scooter. All scooters on island in rentals are chinese made and breaking very often.
Just made East Maui ride today on sportster. Not best bike for that ride ... but we survived.
I researched a lot. Talk to my local friends. Made bunch of calls. ... no luck Harleys and scooters only.
