Electronics

• 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 traction control, quickshift and two engine maps for customized power.
• MAP SELECT SWITCH: Unlock all the potential of your GASGAS dirt bike with the optional Map Select Switch. Designed for maximum control, it features two purpose-built maps, along with traction control and a quickshifter. Fine-tune your power delivery for various terrain, and experience seamless upshifts from second gear upwards. A must-have GASGAS Technical Accessory for everybody wanting to go full gas.
• THROTTLE BODY: The EX 450 F 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. The frame is 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 centralizing 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 GASGAS cross country bike is built with 48mm WP XACT closed cartridge forks for 2024. Easily adjustable by hand on the outside, on the inside, the latest technology prevents foaming for consistent performance, bump after bump. Progressive fork action, thanks to the springs and pressurized oil chamber, is guaranteed while a hydrostop helps you maintain forward momentum by taking the sting out of heavy landings.
• 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 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. Clear chain adjustment markings ensure quick and easy maintenance.

Motor

• MOTOR: Big power on tap! The EX 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 EX 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 EX 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 six-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 EX 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.
• DS CLUTCH: Inside the EX 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 dirt 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.
• INTEGRATED COOLING SYSTEM AND 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 cross country bikes are the Dunlop 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 9.0 L fuel tank is bigger by half a liter 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!
