When it comes to building high-performance 2-stroke dirt bikes, GASGAS sure knows a thing or two! So, for model year 2025, our super-popular MC 85 has undergone a complete overhaul – maximizing power from the motor while introducing an all-new frame and new WP XACT shock, to deliver confidence-inspiring handling and better stability. Not one component on the bike was overlooked by our engineers during the development process of this new generation model. The end result? A super-fun dirt bike that’s easy to ride fast for guaranteed good times!

• GASGAS comes out swinging with an all-new generation MC 85!
• New frame, all-red bodywork, and an updated motor headline the improvements

For youngsters aged between 11 and 15 years old, we know there are a few options out there when it comes to moving up to the 85 class. But at the top of everyone’s list, thanks to a long list of serious updates for 2025, should be the awesome MC 85!

The new generation model has been developed with serious input from a global team of young test riders, with their feedback allowing our highly skilled team of engineers to build what may well be the best production 85cc motocross bike ever made! And just like before, there are two options to choose from with the MC 85 – one with 17”/14” wheels for smaller riders and another with 19”/16” wheels for those kids who grow just that little bit quicker!

The main objective for everyone involved in building the new MC 85 was to make it much easier to ride and control, compared to the outgoing model. There’s an all-new frame that maximizes stability and creates a lighter feel through the turns. A new WP XACT shock for better traction when getting on the gas. A new, lighter swingarm, and new footpegs, too. But wait up, that’s not everything…

Our already awesome MC 85 motor wasn’t overlooked when it came to developing this new bike! Top-end performance was already super impressive for an 85cc dirt bike, so the focus was put on squeezing out more low to mid-range power and boosting torque. And with a new cylinder head, ignition, exhaust, spark plug, and settings inside the KEIHIN carburetor, in addition to the revised airbox for increased airflow, we can safely say it is mission accomplished. Then, to make sure the MC 85 runs at the perfect temperature at all times for maximum power, new radiators, made by PANKL, keep the motor running cool.

And, on top of all that, the motor is repositioned in the frame to help balance the bike out even more. Plus, there’s new, all-red bodywork and new graphics to match the big bikes. The side panels are now even slimmer than before too, so kids can move around much more easily to emulate their GASGAS Factory Racing heroes!

Overall, the new MC 85 is designed to look just like our full size bikes, which lets kids do their thing on a scaled down version of what they can expect to ride when they get a bit older. Trust us, little rippers from around the world are going to love everything about the 2025 GASGAS MC 85. The post-ride smiles will tell you everything you need to know about how good it really is!

Technical Highlights
New frame – All-new for 2025 to improve cornering and stability, especially when getting on the gas out of turns. Frame protectors keep it looking fresh, too.
New WP XACT shock – A new mounting point on the frame and slight reduction in travel creates a more balanced and planted feel for improved traction and control.
Updated motor – A new cylinder head, ignition, spark plug, and carburetor settings boost low to mid-range power and torque.
New exhaust system – Designed in line with the motor updates for maximum performance.

New bodywork and graphics – Mirroring the full size bikes for a sweet new look with slimmer side panels improving control.
New shift drum – Finished with a new coating for strength and smoother shifting.
New swingarm – Lighter in weight by 300g and positioned a little more level than before thanks to the shorter shock and new frame. This leads to a lower back end for easier movement on the bike.
New footpegs – Redesigned to prevent mud from building up for total control in all conditions.
New radiators – Made by PANKL so you just know they’re up to the job of keeping the motor cool!
Redesigned airbox – With improved airflow for maximum performance.
Hour meter – Records time spent on the bike to help you keep on top of routine servicing

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.
