Vehicle Information
GAS GAS EX 450F Dirt Bike (2021-2024)
The GAS GAS EX 450F is a robust cross-country motorcycle, powered by a 449.9 cc single-cylinder engine. From 2021 to 2024, this model was offered as a single version, without special editions or distinct sub-trims, the "EX" designation differentiating it from GasGas's Enduro (EC) and Motocross (MC) lines. The 2021 to 2023 models maintained a largely similar mechanical architecture, featuring a 62 hp engine. However, 2024 brought a major overhaul. The engine was lightened and compacted, the chromoly steel chassis was completely redesigned with a new subframe and swingarm, the front suspension transitioned from an air fork to a coil-spring fork, and the braking system adopted Braktec components. The bodywork was also entirely redesigned for improved ergonomics. Q: Is this product compatible with my GAS GAS EX 450F?
A: To ensure perfect compatibility, please use the year and edition selector at the top of this page.
