We use Honda Lead 110cc. They look like this:
The Honda Lead 110cc is great for people who are used to riding larger motorbikes as well as scooter fans. Perfect for zipping around Rio de Janeiro Zona Sul streets but also for a short trip to Barra, Prainha or even to Vista Chinesa or Floresta da Tijuca. Really comfortable for two friends or two lovers.
Please note: To rent a Scooter 125cc the driver must be at least 21 years old, hold a current motorcycle license for a minimum 3 years, or be licensed to ride a 125cc in their home country.
