Peugeot Speedfight 1 50cc LC 2t - complete data sheet
The Peugeot Speedfight 50cc represents one of the most successful chapters in the history of European sport scooters. Originally launched in 1997, it quickly became a cultural phenomenon among young people, competing directly with iconic models such as the Yamaha Aerox and Aprilia SR 50. With an aggressive, race-inspired design and a revolutionary chassis for its time, the Speedfight 1 laid the foundation for a saga that has sold more than 600,000 units worldwide.
The liquid-cooled (LC) version, produced between 1997 and 1999, stands out for its high-performance 2-stroke single-cylinder engine. Its angular bodywork with dual front optics and sharp lines set the aesthetic trend of the late 1990s. Thanks to its balance between weight and power, it conquered key markets such as Spain, Germany and the United Kingdom, becoming the scooter of choice for those seeking urban mobility with a true sporty character.

Speedfight 1 50cc → Liquid-Cooled (LC) vs. Air-Cooled (AC)
At the launch of the Speedfight 1, Peugeot offered two 2-stroke engine configurations that defined the scooter's character. Although they shared much of their aesthetics, the LC (Liquid Cooled) version was positioned as the high-performance variant versus the AC (Air Cooled) version for the following reasons:
- Power and Speed: The liquid-cooled engine allows for a more aggressive cylinder configuration, resulting in more standard power and a higher top speed than the air-cooled version.
- Thermal Stability: Thanks to the front radiator and coolant circuit, the LC version maintains a constant operating temperature. This avoids the loss of performance (fading) that AC engines suffer when they heat up on long journeys or under sporty driving.
- Superior Braking: A key difference in the chassis is that the Speedfight 1 LC is equipped with a rear disc brake as standard, while the AC version uses a conventional drum, with the liquid version offering much more powerful and precise braking.
- Tuningcapability: For tuning enthusiasts, the LC engine is the ideal base. By better managing heat, it allows 70cc cylinder kits and racing exhausts to be installed more reliably than on air-cooled engines.
- Recommended Use: While the Speedfight AC is an excellent choice for short urban commutes and more economical maintenance, the Speedfight 1 LC is the choice for those looking for sportier handling and maximum mechanical potential.
