Built with world championship winning pedigree, our awesome MC 450F is, well, awesome! This exceptional dirt bike delivers some serious performance, but thanks to plenty of high-level electronic wizardry, the power is put to the ground in a super rideable way. Put simply, you'll be going fast without realizing. An updated frame for 2025 takes the riding experience to new levels by offering more stability when approaching turns while new suspension settings, a redesigned air intake, bigger footpegs, and a stronger rear brake pedal round out the changes for 2025. One thing that stays the same is the unmistakable, all-red bodywork for a classic, GASGAS look.
GRAPHICS
All-new graphics spice things up for 2025 with the GASGAS logo emblazoned in black rather than white for a fresh twist. Still red, still durable, and still eye-catching, the distinctive design is applied using IML technology. This means they're applied within the bodywork so your GASGAS will stay looking super fresh for a long, long time, even if you ride in gnarly conditions week after week.
BODYWORK
All red, front to back! 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, in red of course, 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, NEKEN handlebars are clamped into redesigned 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 in 2025, 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.
FRAME
So much testing and development went into designing and building the frame last year, but our engineers have worked on refining things even further! Thanks to brand new, lighter, motor mounts, the flex characteristics of the frame are improved without any sacrifice to straight-line stability. Around the upper shock mount a little material has been removed while the wall thickness at the front of the frame is also slightly reduced, saving 300g. With all these revisions, which were tested by Red Bull GASGAS Factory Racing in MXGP, the bike is now much more settled through every corner.
SUBFRAME
The all-aluminium subframe is light, strong, and works as one with the new frame by helping to centralize 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
Updated frames for every GASGAS motocross model in 2025 means new settings for the 48mm, split air WP XACT forks. 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.
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?
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 now considerably stronger 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 disks, 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!
WHEELS
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.
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 2025 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.
