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 & 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-liter lightweight polythene fuel tanks feature direct internal line routing from the pump to the flange, for optimal fuel flow.

HANDLING

HANDLING

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.

FORGED TRIPLE CLAMPS

Featuring a 3-way handlebar adjustment that allows riders to set-up the front-end of their bikes just the way they like it, the forged, 22mm offset triple clamps work in harmony with our WP front forks to help deliver precise handling and stability.

FRONT SUSPENSION

All GASGAS motocross models are equipped with advanced, super-lightweight 48mm WP XACT upside-down forks that are easily adjustable. Delivering progressive and consistent damping no matter how rough the track, they feature a capsulated air spring and pressurized oil chamber together with other internal damping wizardry. The end result is outstanding rider comfort and front-end confidence.

REAR SUSPENSION

Traction is what it's all about and our fully adjustable WP XACT rear shock provides the advanced damping that inspires confidence and ignites fun. Designed to work harmoniously with both frame and swingarm to offer incredible energy absorption, the shock is also matched to a linkage system with a specific geometry that further aids traction. Rebound and high/low speed compression adjustment and 300mm of travel means GASGAS motocross bikes are ready to take on the roughest tracks.

SWINGARM

Swingarm: Light, strong and featuring visible chain adjustment marks to make life at the track easier, our motocross swingarms are made using a gravity die-cast process to guarantee durability and precision

MOTOR

MOTOR

MOTOR

Big power and monstrous amounts of torque from a compact SOHC motor that weighs just 27kg, including the electric starter! The MC 450F rips but thanks to centralization being key to the motor's design, the 62 hp power unit is positioned more centrally within the frame, ensuring a positive effect on the bike's overall handling.

CYLINDER HEAD

The MC 450F cylinder head is compact, lightweight and benefits from a short profile that locates the single camshaft as close to the center of gravity as possible. Why? To significantly improve the handling. With lightweight 40mm intake and 33mm exhaust valves activated by rocker arms that are coated in a low-friction Diamond Like Carbon (DLC), the SOHC cylinder head provides both torque and precise throttle response.

CYLINDER & PISTON

Essential to the MC 450F producing strong, smooth power is the lightweight aluminum cylinder and CP bridged-box-type piston. Combined they ensure the motor pumps out an impressive 62hp while also ensuring reduced vibrations.

TRANSMISSION

Transferring power to the rear wheel, the 5-speed transmission is built tough and features motocross specific ratios. Allowing riders to easily hook the next gear and use the bike’s serious torque, the shifting fork features a low-friction coating to ensure silky smooth gear changes each and every time.

CRANKSHAFT

The MC 450F crankshaft is key to the motor delivering great traction and enhanced rideability as well as also helping give the bike its agile handling. Benefitting from long service intervals of 100 hours (who doesn't like those?) a plain big end bearing comprising of two force-fitted bearing shells that ensure maximum reliability and durability.

CRANKCASE

Our high-pressure die cast production process guarantees two things - reliability while keeping overall crankcase weight down. Designed so that the internal moving shafts and parts are carefully positioned, they ensure the best possible handling

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 450F features two-part exhaust systems that are expertly designed to deliver awesome performance at the lowest possible weight. They can also be removed without needing to take out the rear shock! Further innovation allows for a short, compact silencer that keeps sound levels down and looks up.

DDS CLUTCH

The Dampened Diaphragm Steel (DDS) clutch gives riders precise control of the awesome MC 450F. Using a single diaphragm steel pressure plate instead of traditional coil springs, together with a damping system the clutch delivers better traction and durability.

BRAKES

Fast is fun but slowing down is essential, which is why all GASGAS motocross bikes are fitted with Brembo calipers and controls. With 260mm front and 220mm rear disks, braking is easy, inspiring riders to push harder and ride faster.

BREMBO HYDRAULIC CLUTCH

No need for adjustment and a near maintenance-free operation, but the best thing about the Brembo hydraulic clutch is that it delivers a perfectly smooth action time and time again. With lever free-play automatically adjusted, the biting point and function of the clutch remain constant no matter if it's hot or cold.

INTEGRATED COOLING SYSTEM AND RADIATORS

Keeping our bikes slim means better handling, which is why the GASGAS motocross range features cooling systems that are integrated into the frames. Also allowing for improved cooling due to eliminating the need for additional hoses, together with the high-strength, lightweight radiators the complete system ensures, well, our bike stay super cool no matter how tough the conditions!

WHEELS

ENGINE MANAGEMENT SYSTEM - EMS

Super small but the best there is when it comes to processing engine data. Used to control all parameters linked to the fuel-injections system, the Keihin EMS unit also features a gear sensor that allows a tailored power delivery for each gear.

44 MM THROTTLE BODY

The MC 450F uses a 44mm Keihin throttle body with an injector 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 system ensures an immediate throttle response.

ELECTRIC START AND LI-ION BATTERY

No need to kick, kick, kick! All GASGAS 4-strokes motocross bikes are fitted with an electric starter as standard. Saving time at the start of a day when a motor's cold, or near the end of a race when the motor's hot, with the simple press of a button the MC 450F fires into life.
