The motor that does it all! It doesn't matter if you short shift or hang onto every gear, the revitalized MC 250 motor, now with added fuel injection, separates this bike ever further from the competition with it's delivery of usable torque down low and high-revving peak power up top. And it's those who ride wide open that will benefit the most from the counter balancer shaft inside the motor as it keeps vibration to an absolute minimum.
CYLINDER AND PISTON
One of the biggest changes for 2024 is the introduction of elctronic fuel injection on the MC 250. And with this new tech, the traditional 2-stroke power valve is replaced with an innovative electronic exhaust control system. Now, the lateral exhaust ports opens slightly faster than the main exhaust port to deliver strong power and maximum reliability.
Delivering quality, durability, and reliability, the 5-speed transmission by PANKL Racing Systems is built tough, and ensures easy and accurate gear shifting no matter how gnarly the conditions. The lever is cleverly designed to prevent dirt build-up, which is particularly effective when the ruts get deep and the dirt gets sticky!
The magic at the heart of the motor and its low weight means one thing - it revs fast! It's also perfectly balanced for minimal vibration and positioned to have the least amount of effect on overall handling.
Making sure the weight of the MC 250 is kept to a minimum, the thin and strong crankcases are made using a high-pressure die cast process. Inside, the motor internals are positioned to centralize mass, which leads to next level rideability.
Designed and developed to be slim using an innovative manufacturing process, the exhaust system complies with FIM sound regulations, looks awesome, and most importantly, delivers the very best performance! The header pipe is shaped for maximum ground clearance and is fitted to a muffler that features a clever internal construction to keep noise to a minimum without sacrificing power.
Inside the MC 250 motor you'll find a robust and super reliable Damped Diaphragm Steel (DDS) clutch housed inside a CNC machined steel basket. This style of clutch does away with traditional coil springs and instead, there's a single diaphragm steel pressure plate and a damping system which helps get the power to the ground.
Fast is fun but slowing down is essential, which is why all GASGAS motocross bikes are fitted with high quality Braktec calipers and controls. With a 260mm front disk and a 220mm rear disk, both featuring a GASGAS specific design, braking performance is certainly impressive, which inspires riders to push harder, ride faster, and brake later using the redesigned lever.
No need for adjustment and offering a near maintenance-free operation, the best thing about the Braktec hydraulic clutch is that it provides consistent action. With free-play at the redesigned lever automatically adjusted, the biting point and function of the clutch remain constant no matter whether the motor is started from cold or used during the heat of a battle.
Keeping the motor cool are a set of strong aluminum radiators, which channel the air through them in the most effective way possible. A large centre tube within the frame is used to reduce the number of hoses needed and ensures a consistent flow of coolant around the engine - just what you need when you're in the heat of a battle!
Built to take a beating, our wheels are ready to play rough. No matter how heavy the landing or how rough the track is, the silver, CNC machined hubs, lightweight spokes, and high-strength EXCEL rims deliver maximum strength for complete peace of mind.
One of the only components carried over from the outgoing generation of GASGAS motocross bikes are the Maxxis MaxxCross MX-ST tires. Need to know why? It's simple. They perform so well on a wide variety of terrain and they're super-durable too. After all, who likes changing tires?
ENGINE MANAGEMENT SYSTEM - EMS
Small, light, and fast at processing data - just what you need from an engine management system! The Vitesco Technologies component is the best in the business and includes a rollover sensor that cuts the ignition during big crashes, as well as feeding information to the hour meter.
MAP SELECT SWITCH
Installing the Map Select Switch from the GASGAS Technical Accessories range really makes the MC 250 sing! It offers a choice of two maps, and they're both awesome. The first - Map 1 - delivers classic, ripping 250cc 2-stroke power, which all riders know and love. But with the second map activated - Map 2 - throttle response is even sharper and more explosive! Perfect for those who ride sand tracks on a regular basis.
The MC 250 uses a 39mm Keihin throttle body with its injectors positioned to ensure the most efficient flow of fuel mixture into the combustion chamber. But what's most important to all riders is the fact that the direct cable mounting design ensures instant throttle response.
The best invention since the wheel! With an electric starter fitted, this GASGAS starts super easily every single time you hit that start button. And to simplify things further and save space on the bars, the engine stop button is located in the same housing as the start button. Using a Li-Ion battery, which weighs approx. 1kg less than a conventional lead battery, you get the convenience of electric starting while the overall bike weight is kept to a minimum. It's a win, win for everyone!
