Vehicle Information
GAS GAS EC 450 Dirt Bike (2003-2024)
The GAS GAS EC 450 is an iconic enduro motorcycle produced from 2003 to 2024. It is renowned for its off-road performance, powered by a liquid-cooled, four-stroke, single-cylinder engine of approximately 449cc, delivering around 50 horsepower. Over the years, the series has undergone several significant evolutions. Initially launched in 2003 as the EC 450 FSE, it was the brand's first fuel-injected four-stroke enduro. It then evolved into the EC 450 FSR (2008-2009) with visual modifications, followed by the EC 450 (2010-2013), which introduced special editions like the "Cervantes Replica." Between 2014 and 2017, the EC 450F, Racing, and Raid models incorporated Yamaha or Husqvarna-based engines, with specific versions for rally racing. After a period where information on the EC 450 model is more limited (2018-2023), the EC 450F was reintroduced and updated in 2024 under the Pierer Mobility Group, featuring a new chassis and a tilted engine for improved mass centralization.
