Model Description


MC 250 2022

When a light, agile chassis is wrapped around a compact and incredibly powerful 2-stroke 250 cc engine, get ready for some serious, high-revving fun. The new MC 250 delivers everything 2-stroke lovers need to race or play and, most importantly, enjoy a dirt-ripping, heart-pumping ride — and of course Brembo brakes are always there to bring your heartrate back down when needed.
 
BODYWORK
Red with a splash of white. That’s the way we like it! The bodywork fitted to all GASGAS motocross bikes not only reflects our vibrant, Spanish personality but also ensures complete harmony between rider and bike. Considered ergonomics allow unrestricted movement while our flat, high-grip seat profile delivers comfort and control in all conditions.
 
AIRBOX
Less time working on bikes means more time riding bikes, which is exactly why you’ll love the straightforward, no tools needed filter mounting system on all GASGAS motocross bikes. Allowing quick and easy filter changes, the airbox is designed with precisely positioned inlet ducts that ensure maximum airflow and protection of the Twin Air filter. 
 
HANDLEBARS, GRIPS AND THROTTLE ASSEMBLY
Hold on, it’s important! We fit all GASGAS motocross bikes with quality Neken tapered handlebars, guaranteeing comfort and control thanks to optimal pressure points on rider’s hands. The left side ODI grip doesn’t require gluing, while on the right, the vulcanized grip features an innovative integrated throttle mechanism. With easy to adjust free-play, by changing a cam, the progression of the throttle can also be altered.
 
FUEL TANK
We like to keep our fuel tanks simple and robust, that’s why we opted for a threaded filler cap that provides a tight and reliable seal and positioned the external fuel line to make sure it’s less exposed and susceptible to damage. The black 7-litre lightweight polythene fuel tanks feature direct internal line routing from the pump to the flange, for optimal fuel flow.
 
FRAME
The technology in our frames ensures riders enjoy playful handling and an energetic feeling on any motocross tracks. Underneath the red powder coating there’s a lightweight chromium molybdenum steel, hydro-formed, laser-cut and robot-welded chassis that’s built to perform. Designed to be rigid where it needs to be rigid and to flex where flex is needed, it provides exceptional rider feedback, energy absorption and straight-line stability.
 
SUBFRAME
With a short and compact profile all GASGAS motocross subframes are made from lightweight aluminum. The profile helps centralize mass while also keeping weight down.
 
MOTOR
The MC 250 is powered by a compact 2-stroke motor with a counter-balancer shaft for smooth, high-revving power. Delivering lots of torque, our power unit makes the bike super easy to use but also highly competitive – thanks to innovations like a twin-valve controlled power valve. Designed to centralize all internal moving parts, the motor also plays a huge role in the bike’s agile handling.
 
CYLINDER AND PISTON
The MC 250’s cylinder has a bore of 66.4 mm and is fitted with a twin-valve power valve system to churn out serious power across the rev range. The exhaust port is machined for precise power valve function, providing excellent overall power delivery. A lightweight piston keeps the motor turning freely for playful, quick-revving fun. 
 
CARBURETTOR
A 38mm flat slide Mikuni TMX carburetor ensures our 2-stroke screamer receives a constant supply of fuel, filling the motor with energy and giving riders smooth and controllable power across the full rev range.
 
TRANSMISSION
Delivering quality, durability and reliability, the 5-speed transmission by PANKL Racing Systems is built tough, and does ensure easy and accurate gear shifting no matter how tough the conditions. The lever features an innovative tip design that prevents dirt build-up when ruts get deep and the dirt get sticky!
 
CRANKSHAFT
The magic at the heart of the motor! Made to be as light as possible and balanced perfectly to reduce unwanted vibrations, the 72mm stroke crankshaft is positioned to ensure it has little effect on handling while allowing the 250cc motor to produce it’s high-revving fun.
 
CRANKCASE
Key to keeping the weight of the MC 250 to a minimum, the motor’s thin and strong crankcases are made from a high-pressure die cast process. Allowing motor internals to be positioned closer together, the compact design allows for improved centralization of masses while ensuring the highest levels of rideability. A durable kickstart intermediate gear ensures exceptional starting reliability.
 
EXHAUST SYSTEM
Our exhaust systems are key to the power delivery of all GASGAS motocross bikes. Developed to be slim using an innovative 3D process, they comply with FIM sound regulations, look great and most importantly deliver the very best performance. The MC 250 header pipe offers optimal geometry, performance and ground clearance and is fitted to a muffler that features an advanced internal construction for excellent noise damping.
 
DDS CLUTCH
The MC 250 features a Dampened Diaphragm Steel (DDS) clutch, which is robust, super reliable and contributes to the compact design of the engine. Featuring a single diaphragm steel pressure plate instead of traditional coil springs, it also has a clutch basket CNC machined from a single piece of steel.
