Features
High-Performance 449.9cc SOHC Engine

The compact liquid-cooled 449.9cc four-stroke engine delivers impressive peak power while maintaining smooth, controllable performance throughout the rev range. A lightweight aluminium cylinder and CP bridged box-type piston combine with a high 13.1:1 compression ratio to produce exceptional acceleration and broad, usable torque. The compact SOHC cylinder head helps reduce engine weight while improving mass centralisation for agile handling.

Lightweight Chromium-Molybdenum Steel Frame

Built around a central double-cradle 25CrMo4 chromium-molybdenum steel frame, the MC 450F offers the ideal balance of stability, rider feedback, and agility. Optimised flex characteristics improve cornering precision and traction, while the lightweight aluminium subframe contributes to balanced handling and race-ready durability.

WP XACT Suspension

Premium WP XACT 48 mm AER air forks work together with a fully adjustable WP XACT rear shock to deliver exceptional suspension performance. The race-developed package provides excellent bump absorption, predictable handling, and maximum traction while allowing riders to quickly tailor settings for changing track conditions.

Advanced Electronic Fuel Injection

A 44 mm Keihin throttle body provides immediate throttle response and highly accurate fuel delivery. The advanced engine management system continuously optimises performance, while individual gear mapping helps maximise traction and power delivery throughout every lap.

Five-Speed Racing Transmission

Manufactured by PANKL Racing Systems, the five-speed gearbox has been engineered for fast, precise shifting under race conditions. A redesigned shift shaft reduces shift effort while a gear position sensor allows the engine management system to optimise performance for every gear.

DDS Hydraulic Clutch

The Damped Diaphragm Steel (DDS) clutch features a single diaphragm spring and is housed within a CNC-machined steel basket. Operated by a Braktec hydraulic system, it delivers a light lever feel, consistent engagement, and virtually maintenance-free operation with automatic wear compensation.

Powerful Race Braking System

Hydraulic disc brakes provide strong, progressive stopping power with excellent feel under all riding conditions. Combined with redesigned brake controls and high-quality brake discs, the braking package gives riders the confidence to brake later and maintain greater control entering corners.

Rider-Focused Ergonomics

Slim bodywork, a flat seat profile, and carefully positioned rider contact points allow unrestricted movement around the motorcycle. The ergonomic layout encourages aggressive riding while reducing fatigue, making it easier to stay in control during long motos and demanding race conditions.

Premium Competition Components

The MC 450F comes equipped with premium race-ready components including Neken aluminium handlebars, black lightweight wheels, Maxxis MaxxCross MX-ST tyres, high-strength hubs, and durable aluminium controls. Every component has been selected to maximise durability, performance, and rider confidence.

Signature GASGAS Styling

Finished in GASGAS's signature all-red bodywork with bold black graphics, the MC 450F reflects the appearance of the brand's factory motocross machines. Slim body panels and race-inspired styling not only create an aggressive look but also improve rider mobility throughout every lap.
