Peugeot Speedfight 4 50 4T ac

The Peugeot Speedfight saga is one of the historical references among 50 cc sport scooters in Europe. Since its appearance in 1997, it has been characterized by an aggressive aesthetic, a robust cycle part and an agile behavior in the city. Throughout its generations, the model has evolved technically while maintaining its sporty approach for everyday use.

The Peugeot Speedfight 4 50 4T (AC), produced since 2015 and now adapted to Euro 5 standards, is the most balanced choice for the urban environment.
