New GasGas MC 450F model details, with links to new and used dealer listings and latest GasGas deals

Power when you need it, fun when you want it! The world championship-winning MC 450F delivers smooth, strong performance, whether you're flowing through tracks or launching into the next jump. Thanks to plenty of electronic wizardry, all that power stays super rideable, so you're going fast without even thinking about it. The updated chassis from 2025 rolls into 2026 unchanged, keeping the same confident handling, stability, and comfort that riders love. What's new is the look: bold black graphic details and elements add a fresh twist to the unmistakable GASGAS red for a clean, modern style that stands out on any track.

GRAPHICS
Black graphic details bring a bold twist to the signature GASGAS red, with a clean white logo that pops right off the dark background. Other blacked-out parts like the seat cover, handlebar, and rims dial up the style to really set things off. Thanks to durable IML technology, the graphics are built into the bodywork to keep your GASGAS looking sharp, ride after ride.

BODYWORK
Proudly red, with sharp black details! Incredibly ergonomic with large contact surfaces to help you grip the bike with your legs, the smooth profile bodywork encourages riders to effortlessly move around on the bike and ride with a perfect technique. There's also a super grippy seat cover, now in black, to keep you sat exactly where you need to be when you get on the gas!

HANDLEBARS
Get on the gas and hold on tight! Not too tight though as nobody likes arm pump... But to make sure the ride is comfortable, black NEKEN handlebars are clamped into optimized bar mounts (they're more resistant to twisting if you should hit the deck), with lock-on style, medium compound ODI grips fitted to create a comfy set-up to suit all riders.

AIRBOX
Less time working on bikes means more time riding bikes, which is precisely why you'll love the straightforward, no tools and no-nonsense filter mounting system. With a stronger one-piece design for the air intake, maximum airflow is guaranteed, and you know what that means... maximum power! Like before, accessing the air filter to inspect or replace it couldn't be easier. Simply pop the left side panel off and you'll be inside the airbox in no time.

FUEL TANK
The fuel tank sits neatly inside the vibrant red bodywork and a beefie rubber tank support underneath helps hold it firmly in place while protecting the frame from wear. With an integrated fuel pump inside the tank, long motos around deep sand tracks aren't a problem for this GASGAS!

FOOTPEGS
Bigger is better when it comes to footpegs. That's precisely why they not only have a large surface area for maximum grip, but we've also made them less likely to catch on the edges of deep ruts, which mean no loss to forward momentum. The pegs are also light and prevent mud from building up. So, no matter how gnarly the track gets, you'll stay in complete control.

FRAME
The current frame hits the sweet spot between razor-sharp handling and just the right amount of flex. Lightweight motor mounts dial in the feel without messing with straight-line stability, and smart material tweaks, like a slimmed-down upper shock mount and reduced wall thickness up front, save 300g. Developed with the GASGAS Factory Racing crew, it's a setup that stays planted and lets you push harder in every turn with a big smile in your face.

SUBFRAME
The all-aluminium subframe is light, strong, and works as one with the mainframe by helping to centralizing mass and contributing massively to the bike's outstanding handling characteristics.

TRIPLE CLAMPS
Forged aluminum triple clamps offer just the right amount of calculated flex thanks to a more forgiving steering stem. The triple clamps align the fork tubes perfectly for a smooth action, which improves front wheel feedback and leads to predictable handling on any track and any terrain. The adjustable bar mounts with the slightly larger contact area against the handlebars reduce the chance of the bars twisting. A glass bead blasted finish means the triple clamps always look as good as new.

WP FORKS
Our GASGAS motocross models come with a 48mm, split air WP XACT fork with model specific set ups to ensure the best performance. Continuing to be easily adjustable by hand on the outside, on the inside, a capsulated air spring and pressurized oil chamber take care of delivering consistent damping. By using an air spring, a customized set-up can be created easily as this bike includes an air pump to adjust the pressure. And, for those who like to go big on the jumps, a hydrostop in the forks help maintain forward momentum by taking the sting out of every heavy landing.

WP SHOCK
With no less than 300mm of travel, the WP XACT rear shock effortlessly absorbs even the biggest bumps. While the shock remains the same, it continues to deliver top-tier performance, thanks to years of development and feedback from the MXGP circuit. The settings are fine-tuned to work perfectly with the frame, offering optimal damping straight from the showroom floor. And adjusting your set-up? It's still quick and easy with simple hand adjustments, giving you full control to dial it in.

SWINGARM
Cast from one piece of aluminum, the swingarm on this GASGAS certainly looks the business! A strong chain slider ensures durability and keeps the chain running smooth for long time. At the rear of the swingarm you'll find a chain guide with a rounded profile to help it glide over the ground as you lay the bike over through deeply rutted turns. Finally, clear chain adjustment markings ensure quick and easy maintenance.

MOTOR
Big power on tap! The MC 450F delivers monstrous amounts of torque and peak power from its compact SOHC motor. And as Jorge Prado proved in 2023, we don't need to tell you that the MC 450F absolutely rips! But thanks to a little engineering wizardry and by being perfectly positioned inside the frame, the motor centralizes mass for superior handling. In short, this bike rides and handles like a dream.

CYLINDER HEAD
There's a lot packed into this SOHC cylinder head! Designed to be light and compact, it sure delivers the best on-track performance. The intake ports are engineered to pump up the horsepower numbers while a fine-punched cam chain is used for maximum reliability.

CYLINDER & PISTON
Essential to the MC 450F producing strong, smooth power is the lightweight aluminum cylinder and CP bridged-box-type piston. By bumping up the compression ratio to 13.1:1, our engineers have improved performance with the motor now pumping out an impressive peak power that will water your eyes!

TRANSMISSION
Built by PANKL Racing Systems, you just know that the 5-speed transmission is going to be good! A perfectly engineered shift shaft reduces the force you'll need to change gears, both up and down the box, for silky smooth shifting at all times. Plus, there's a sensor on the shift drum which, together with the engine management system, activates an engine map tailored for each gear. Pretty clever, right?

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 90 hours, a plain big end bearing comprising two force-fitted bearing shells to ensure maximum reliability and durability.

CRANKCASE
The protective housing keeping all the internal components safe and secure! Designed to centralize every internal part, the crankcases themselves are thin yet strong and lightweight thanks to being made using a high-pressure casting process.

EXHAUST SYSTEM
Put simply, the exhaust system is designed to deliver the very best performance at the lowest possible weight! Wrapping neatly around the motor, the two-piece header pipe feeds into a short and compact aluminum silencer. Updates to the exuast and airbox for 2026 keep the sound levels well within the latest AMA and FIM regulations.

DIAPHRAGM STEEL (DDS) CLUTCH
Inside the MC 450F 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.

HYDRAULIC BRAKES
Fast is fun but slowing down is essential, which is why all GASGAS dirt bikes are fitted with high quality BRAKTEC calipers and controls. Speaking of controls, the rear brake pedal is extra strong to prevent it from getting bent out of shape in a crash or catching the ground when you're railing through a deep rut. When you combine those BRAKTEC calipers with GASGAS specific brake discs, 260mm up front and 220mm at the rear, the end result is amazing braking performance. This all means that all riders can stay on the gas longer and brake later into corners. And we all know what that leads to... faster lap times!

HYDRAULIC CLUTCH
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.

RADIATORS
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! Plus, a new cooling radiator closure makes operation easier, allowing for quicker and smoother maintenance when needed.

WHEELS
Now in sleek black and 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.

TIRES
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 Keihin component is the best in the business and engages each gear's engine map, includes a rollover sensor that cuts the ignition during big crashes, and feeds information to the hour meter. Plus, if you install a Map Select Switch (available from your local GASGAS dealer as a Technical Accessory), it instantly synchronizes for plug and play simplicity and gives your bike Launch Control, Traction Control, the Quickshifter function and a two engine maps for customised power.

MAP SELECT SWITCH
Readily available as a Technical Accessory, the easy to install Map Select Switch really makes this GASGAS come alive! Offering plug and play simplicity, once fitted you'll enjoy multiple benefits. There's Launch Control for perfect starts, every time. Traction Control for hardpack and slippery conditions. And a Quickshifter function that allows full gas upshifting. Oh, and there's also a choice of two engine maps. Map 1 (Mellow) delivers predictable power for all kinds of tracks and is suited to just about all riders. But with Map 2 (Aggressive) engaged, hold on tight, things will get wild!

CONNECTIVITY UNIT OFFROAD (CUO) & GPS SENSOR
For our 4-stroke motocross models, GASGAS is stoked to put engine tuning into the rider's hands. All you need to do is download our new GASGAS+ app, pair your device with the Connectivity Unit Offroad (CUO) and the GPS sensor that you can buy as a Technical Accessory, then with a few quick taps, you can access all the app's features.Within the GASGAS+ app there are three main sections - ENGINE, SUSPENSION, and RIDER. The ENGINE feature allows you to customize and control the power delivery based on your style or the track conditions while the SUSPENSION feature offers recommended settings for different types of circuits. Multiple set-ups, for both the engine and suspension can also be saved for future reference. Finally, the RIDER feature is where your lap times are recorded along with the ability to analyze everything about how your bike is running.

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 STARTER
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!
