Can I ride a scooter (pasola) from Las Terrenas to Las Galeras?

After staying in Las Terrenas for 10 years, we started to think about exploring the eastern tip of the peninsula, Las Galeras. Our next question is: Is riding a scooter (pasola), a moped, from Las Terrenas to Samana a good idea? Specifically, we were thinking about taking highway number 7 from Las Terrenas to Sanchez and then number 5 from Sanchez to Las Galeras.
