Vehicle Information
GAS GAS EX 250 Dirt Bike (2022-2025)
The GAS GAS EX 250 series (2022-2025) offers high-performance cross-country motorcycles designed for off-road enthusiasts. This range includes two distinct models: the EX 250 with a two-stroke engine and the EX 250F with a four-stroke engine. These vehicles are known for their agility and robustness, providing a dynamic riding experience across various terrains. Significant developments occurred during this period. The EX 250 two-stroke saw its fuel injection system transition from TPI (Transfer Port Injection) to TBI (Throttle Body Injection) in 2024, a year in which it was completely redesigned. The 2025 model then received chassis, suspension updates, and a new Pankl transmission. The EX 250F four-stroke also underwent a major overhaul in 2024, featuring a new engine based on the KTM 250 XC-F powerplant and an updated chassis. The 2025 model continued this trend with further frame and suspension enhancements. Q: How can I ensure parts fit my GAS GAS EX 250?
