Electronics

• ENGINE MANAGEMENT SYSTEM - EMS: Small, light, and fast at processing data - just what you need from an engine management system! The Vitesco Technologies component is the best in the business and includes a rollover sensor that cuts the ignition during big crashes, as well as feeding information to the hour meter.
• 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 delivers predictable power for all kinds of tracks and is suited to just about all riders. But with Map 2 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.
• HAPPY BUTTON: 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!

Handling

• FRAME: A generation bike is nothing without a frame, right? Taking the best traits from the old frame, which if you didn't know combined razor-sharp cornering with confidence-inspiring straight line stability, our engineering wizards have made it even better! They've improved the anti-squat behavior for maximum traction when exiting corners. Throughout the frame, the wall thickness has been revised in certain areas to improve rider feedback and energy absorption. Finished with a red powder coating and grippy guards to prevent wear, which provide a little extra grip for your boots too.
• SUBFRAME: The all-aluminum subframe is light, strong, and works as one with the frame by helping to centralize mass and contributing massively to the bike's outstanding handling characteristics.
• FORGED 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 smoother action, which improves front wheel feedback and leads to predictable handling on any track and any terrain. There are adjustable bar mounts with a slightly larger contact area against the handlebars so if you crash, there's less chance of twisting the bars. A glass bead blasted finish means the triple clamps always look as good as new, too.
• WP FORKS: Every full size GASGAS motocross model is equipped with improved 48mm WP XACT forks for 2024. Easily adjustable by hand on the outside, on the inside, they feature revised settings that specifically work with the frame. Progressive fork action is retained thanks to the capsulated air spring and pressurized oil chamber while a hydrostop takes the sting out of heavy landings and helps to maintain forward momentum.
• WP SHOCK: Soaking up the bumps with ease, the redesigned WP XACT rear shock is shorter and lighter than the old version but still offers 300mm of travel. Inside there's been some technical changes with a piston improving initial comfort and helping to stay up a little higher in the stroke, especially when under hard acceleration. And just like the WP forks, the WP shock is adjustable by hand so it's quick and easy to dial things in should you need to.
• SWINGARM: Cast from one piece of aluminum, lower in weight than the old one, and slightly stiffer, the swingarm on this GASGAS is as good as it gets! There's also a much more durable chain slider and the guide is much more rounded to help prevent catching the ground as you lay the bike over through deeply rutted turns. The swingarm is complete with a 22mm rear wheel axle to complement the refined flex characteristics of the entire chassis. Finally, clear chain adjustment markings ensure quick and easy maintenance.

Motor

• MOTOR: Big power on tap! The MC 450F motor delivers monstrous amounts of torque from its compact SOHC motor, which our engineers have reduced in weight for 2024. We don't need to tell you that the MC 450F absolutely rips but thanks to a little engineering wizardry, and a slight tilt backwards in the frame, the motor further centralizes mass in addition to significantly improving anti-squat behavior. In short, this bike handles like a dream.
• CYLINDER HEAD: There's a lot packed into this SOHC cylinder head! Redesigned to be lighter and more compact, it sure helps to deliver the best on-track performance possible. The intake ports have been revised to pump up the horsepower numbers while a fine-punched cam chain further improves the reliability that this bike's known for.
• 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: Transferring power to the rear wheel, the redesigned 5-speed transmission is built by Pankl so you know it's going to be good! With an updated shift shaft reducing the force needed to change gears, shifting up and down the box, which features revised gear ratios, is silky smooth. 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 that keeps all internal components safe and secure! Redesigned to centralize all internal parts, the crankcases 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 that keeps the sound levels well within the FIM regulations.
• 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.

Parts

• HYDRAULIC BRAKES: Fast is fun but slowing down is essential, which is why all GASGAS motocross bikes are fitted with high quality Braktec calipers and controls. With a 260mm front disk and a 220mm rear disk, both featuring a GASGAS specific design, braking performance is certainly impressive, which inspires riders to push harder, ride faster, and brake later using the redesigned lever.
• 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 center 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.
• 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?

Style

• BODYWORK: All red and fully redesigned from front to back, the sleek bodywork is incredibly ergonomic with larger contact surfaces and an improved rider triangle that further enhances control. The rad shrouds are shaped to help you grip the bike more as you get on the gas with a super grippy seat cover keeping you firmly in place.
• HANDLEBARS: Get on the gas and hold on tight! Not too tight though as nobody likes arm pump... But to make sure you stay comfortable, Neken handlebars are clamped into redesigned bar mounts (which are less 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 most 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. Allowing quick and easy filter changes, the airbox is designed with precisely positioned inlet ducts to direct the flow of air towards the Twin Air filter to create maximum horsepower.
• FUEL TANK: The fuel tank is slightly bigger when compared to the outgoing generation, but it's still just as sleek. With an integrated fuel pump allowing the tank to be emptied further before refueling is needed, long motos around sand tracks are definitely not a problem for this GASGAS!
• FOOTPEGS: Bigger is better when it comes to footpegs, which is why on the models there's a bigger platform for better control. Plus, thanks to a mounting design, they're further inward on the frame, which makes them less prone to catching the edge of deep ruts or jump take offs, for those who like to scrub!
