Remember that these scooters are driven hard and not a lot of money for repairs. We drove 70K into the countryside and one scooter had mechanical troubles. We limped it back Varadero and it died. Don't get stranded!
I got stung by a bee outside of Caderas, so be aware of that.
Finally, don't get drunk and ride. I have seen a few people at the airport with road rashes and wounds from crashing.
