2025 Gasgas MC 300


One year on from launching an all-new generation of motocross and cross-country bikes, GASGAS is spicing things up again with a revitalised line-up that includes two new 2-stroke models for 2025 (Australia only). Existing bikes across both ranges now feature revised frames, motor mounts, swingarms, suspension settings, and linkages to ensure each one is even more fun to ride.

Gas Gas has introduced an MC 150 and an MC 300 to their motocross line-up. The little MC 150 uses the foundations of their super-popular MC 125 but takes power, and more importantly, torque, to a crazy new level for such a small-capacity dirt bike.

And the same can be said for the MC 300, which is based on their versatile MC 250. Offering up plenty of power, it’ll be the super useable torque curve that 2-stroke fanatics worldwide are going to love most about the MC 300. Both bikes are built using the same high-quality components you’ll find on all Gas Gas motocross and cross-country models for 2025. Such as the revised frame design…

The Gas Gas engineers have removed a little material around the upper shock mount as well as reducing the thickness of the frame at the front. In addition to saving 300g, what’s more important is that these revisions were made to significantly improve handling, especially when entering corners, without sacrificing any straight-line stability. New motor mounts further refine the frame’s flex characteristics with revised suspension settings introduced to complement the chassis changes and help elevate the riding experience.

A stronger air intake sleeve prevents flex to maintain maximum airflow. At the rear of each bike, the swingarm is updated to enhance the durability of the chain slider, which is made from a more hard-wearing material to boost longevity. The linkage is now put together with new, lower-friction SKF seals to help the WP rear shock perform just that little bit better. Plus, there’s also a smaller linkage bolt to reduce weight and play a part in delivering the refined flex characteristics from the updated chassis.

Every cross-country model features all of the revisions above in addition to being assembled with a sprinkling of components exclusive to the range. An 18” rear wheel is wrapped with a DUNLOP AT81 tyre that’s paired with a DUNLOP MX33 tyre on the front, there’s a handy side stand, and for the 4-strokes, there’s a new PANKL transmission with ratios developed specifically for cross country style riding.

You’ll find the motocross range in authorised dealerships in Australia and New Zealand from August 2024, and the cross-country line-up from October 2024. Please note that the MC 150 and MC 300 motocross models will not be available in New Zealand.
