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 behaviour. 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 new, fine-punched cam chain further improves the reliability that this bike's known for.
CYLINDER AND 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.
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 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.
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 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!
