Vehicle Information
GAS GAS EX 350F Dirt Bike (2021-2025)
The GAS GAS EX 350F, offered from 2021 to 2025, is a prominent cross-country race bike known for its balanced performance. This off-road motorcycle consistently features a single-cylinder, liquid-cooled, DOHC 350cc engine, delivering impressive torque and over-rev capabilities suitable for demanding terrains. Throughout these years, it maintained a single trim level, focusing on its core mission as a competitive off-road machine. While the core engine remained consistent, the 2021-2025 period saw continuous refinements. The 2025 model year, in particular, marks a significant new generation for the EX 350F. Key updates include an all-new chromoly steel frame with enhanced flex characteristics, revised suspension settings featuring a WP Xact coil-spring fork, and a new Pankl Racing Systems six-speed transmission. These changes, alongside new engine mounts and chassis components, aim to further optimize performance and durability. Earlier years saw updates to suspension settings, electronics, and compression ratios. Q: How do I ensure I'm selecting the correct parts for my GAS GAS EX 350F?
