Vehicle Information
GAS GAS EX 250F Dirt Bike (2021-2025)
The GASGAS EX 250F, available from 2021 to 2025, is a cross-country motorcycle known for its performance and versatility. This singular model, without distinct trim levels, is powered by a 249.9 cc or 250 cc single-cylinder engine. Initially launched in 2021 with WP Xact suspension and a chassis blending KTM and Husqvarna components, it saw minor refinements in 2022 and 2023. A major platform revision occurred in 2024. This model introduced an entirely new chassis featuring a double-cradle chromoly steel frame, an all-aluminum subframe, and a die-cast swingarm. Suspension was upgraded with a WP Xact closed-cartridge coil-spring fork and a new Xact shock. The engine also received updates with new bore and stroke dimensions (81.0 x 48.5 mm). For 2025, the EX 250F received further refinements to its frame, suspension, and air intake, optimizing handling and stability. FAQ:
