MC 85 19/16

The 2025 GasGas MC 250 combines two-stroke performance with modern refinement, delivering a ride that’s both thrilling and confidence-inspiring. Its updated, more flexible frame retains rock-solid straight-line stability while offering improved agility through corners, resulting in a machine that reacts with precision yet feels planted. Rider ergonomics have been refined with grippy contact surfaces and in-mould bodywork that invites movement and control, making every trail or track session feel seamless and engaging. This bike brings out the best in riders, whether pushing for race pace or enjoying a spirited weekend ride.​​

 Re-engineered Engine & Weight Balance Underneath, a performance-tuned 84.9 cc two-stroke motor benefits from significant updates including a new cylinder head, refined ignition, revised carburettor settings, and an upgraded exhaust system—resulting in stronger low-and mid-range torque without sacrificing rev-happy top-end delivery. The motor housing has been rotated back by three degrees compared to previous iterations, enhancing weight distribution and delivering notably improved balance. Overall, the engine is now lighter by approximately 120 g, directly contributing to sharper handling and a more exhilarating ride.
Supreme Suspension & Handling GasGas has elevated ride quality with updated suspension and chassis geometry. A new WP XACT rear shock, mounted in a revised position, provides enhanced traction and a more planted feel, while the 19/16 wheel configuration improves ground clearance and overall stability. The denser, lighter swingarm is trimmed by 300 g and sits flatter thanks to the updated shock length, helping young riders shift their weight intuitively. Adjustable WP XACT 43 mm USD forks paired with revised steering geometry refine corner articulation and control, fostering a handling package that feels sophisticated and confidence-inspiring.
Racer-Grade Finishing Touches & Practical Upgrades This youth motocross model includes thoughtful racing-level embellishments: redesigned footpegs shed mud more effectively, a lighter shift drum ensures smoother shifts, and high-capacity radiators by a renowned specialist keep the engine cool under intense use. The updated airbox promotes improved airflow, and a convenient hour meter supports maintenance tracking. Ergonomic touches like tapered handlebars, scaled-down fuel tank, and self-cleaning gear selector enhance rideability and usability. Every feature reinforces confidence, durability, and a keen-to-ride personality, making the MC 85 19/16 a true performance bike for junior racers.
