GASGAS Adds Two High-Revving 2-Strokes to 2025 Motocross Line-Up!

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

• New and improved GASGAS dirt bikes revealed for 2025
• Huge choice of models means there’s something for everyone
• Available in dealers from July onwards

Riders ask, GASGAS delivers! That’s right 2-stroke fans, GASGAS has introduced an MC 150 and an MC 300 to its motocross line-up! By expanding the offering, GASGAS really does now have a bike for everyone – from beginner to pro and every rider in between. The little MC 150 uses the foundations of the super-popular MC 125 but takes power – and more importantly – torque to a crazy new level for such a small capacity dirt bike.

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

Removing a little material around the upper shock mount and reducing thickness at the front end of the frame has resulted in the new motocross range shedding some weight for 2025 – 300 grams in total. These revisions significantly improve handling – especially when entering corners – without sacrificing any straight-line stability. New engine 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 suspension linkage now uses new, lower friction SKF seals to allow the WP Suspension rear shock to perform at its best, with a smaller linkage bolt reducing weight and playing a part in delivering the refined flex characteristics from the updated chassis.

Technical Highlights
