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.
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.
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.
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.
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.
WP SHOCK
With no less than 300mm of travel, the WP XACT rear shock soaks up the biggest of bumps with ease. For 2025, the performance of the shock is taken up a notch thanks to the new, lower friction seals in the linkage and a smaller diameter linkage bolt, to reduce a little weight. Both revisions were put to the test in MXGP, so you know they'll make a difference. Because of the new frame, the shock's settings have been revised to deliver the best damping straight from the showroom floor. However, creating a customized set-up remains super simple as adjustments can still be made quickly by hand.
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.
CRANKSHAFT
Up and down, round and round... life's tough being a 350F crankshaft! So it's a good job that the spinning heart of the MC 350F motor is super durable with service intervals of 90 hours. Not only designed for maximum performance, the crankshaft is positioned to help centralize oscillating masses, which creates a super agile and lightweight feel to the bike while riding.
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 that keeps the sound levels well within the FIM regulations.
DIAPHRAGM STEEL (DS) 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.
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.
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.
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!
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!
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!
