GasGas ’ dirt bike lineup has grown since 2021 and continues to do so in 2025 with the addition of two models to its full-size motocross bike lineup. The fun Austrian brand now offers an MC 150 for those who want a little more oomph than a 125cc two-stroke as well as an MC 300 to suit the desires of power-hungry two-stroke MX riders far and wide. The MC 125 and MC 250 bring the premix-burning model count to four, and the four-stroke trio of the MC 250F , MC 350F , and MC 450F are familiar models in the range too.
GasGas’ entire full-size motocross bike lineup features a reworked double-cradle chromoly steel frame to provide more chassis flex. GasGas All seven models feature an updated double-cradle chromoly steel frame for improved chassis flex characteristics, cutout engine mounts, and a revised swingarm and chain slider for better durability and wear of the chain. Shock linkage has been updated for optimized stiffness with different seals and a smaller-diameter bolt for weight savings. The WP Xact AER 48mm fork and WP Xact shock on each machine houses updated settings to match the reworked frame and shock linkage.
The MC 150 is a new model to GasGas’ lineup in 2025. GasGas Further shared changes include an air intake sleeve and snorkel that are now a one-piece design to prevent deformation, and an updated rear brake caliper that’s said to be more robust. Also, a new rubber piece is applied to the frame where the fuel tank sits to hold it in place better and keep the frame protected. Fresh graphics with more black than white helps distinguish the MY25 red Austrian MX bikes from the 2021–2024 models.
Suspension settings on all of the fun Austrian brand’s full-size motocrossers have been changed to match the updated frame. GasGas The seven MY25 GasGas full-size motocross bikes will land in dealerships beginning this month. Suggested retail prices and full spec sheets for them are listed below.
