Features & Benefits

HANDLING

FRAME

If you're going to race in the woods, you need to be tough! We build our frames to be tough using lightweight, laser-cut chromium molybdenum steel, which is robot welded for complete accuracy. We also ensure riders have complete confidence crossing tree roots and rocks thanks to specifically engineered flex. Together with proven geometry, our frames deliver playful handling and the very best stability and are finished with a durable, red powder coating.

SUBFRAME

With a short and compact profile all GASGAS cross country subframes are made from lightweight aluminum. The profile helps centralize mass while also keeping weight down.

FORGED TRIPLE CLAMPS

Our triple clamps offer 4-way handlebar adjustment, which ensures riders of all sizes can accurately set the handlebars to best suit their needs. Featuring a 22mm offset the forged triple claps also ensure maximum stiffness for precise handling and front suspension action.

WP FORKS

Set-up for woods competition, all GASGAS cross country bikes comes fitted with 48mm WP XACT front forks with AER technology, providing incredible front-end damping for complete rider control. Firm enough to consistently handle high-speed bumps while also supple enough to ensure outstanding comfort across rough, broken edged terrain, they feature easy access clicker dials for quick adjustments and perfect rider set-up. Effective internal wizardry ensures consistent damping no matter how rough the terrain.

WP SHOCK

Matched to the linkage system fitted to all GASGAS cross country bikes, the WP XACT rear shock deliver 300mm of rear wheel travel to ensure awesome handling, the very best traction and maximum fun in the woods. With specific internal settings giving riders complete confidence across a wide-range of offroad terrains, in offering full rebound and high/low-speed compression adjustability the shock can easily be fine-tuned to meet the needs of beginners and seasoned racers alike.

SWINGARM

Exceptional strength at the lowest possible weight, and with visible chain adjuster marks to make chain adjustment quick and accurate. Our hollow, die-cast swingarms deliver durability and precision.

Features & Benefits

MOTOR

Make no mistake about it, the EX 450F rips! But thanks to centralization being key to the compact SOHC motor's design, the 62hp power unit is positioned more centrally within the frame, ensuring a positive effect on the bike's overall handling. It weighs just 27.3kg, including the electric starter!

CYLINDER HEAD AND BALANCER SHAFT

The EX 450F cylinder head is compact, lightweight and benefits from a short profile that locates the single camshaft as close to the center of gravity as possible. Why? To significantly improve the handling. With lightweight 40mm intake and 33mm exhaust valves activated by rocker arms coated in a low-friction Diamond Like Coating (DLC), the SOHC cylinder head produces both torque and precise throttle response.

CYLINDER & PISTON

Essential to the EX 450F producing strong, smooth power is the lightweight aluminum cylinder and CP bridged-box-type piston, which only weighs 320g. Combined they ensure the motor pumps out an impressive 62hp while also helping to reduce vibrations.

Transmission

The 5-speed transmission fitted inside the EX 450F motor ensures smooth and precise shifting and is designed to be extremely light and durable while delivering maximum power from the engine to the rear wheel. The shifting fork has a low-friction coating for smoother gear changes while the gear lever is designed to prevent dirt build-up and ensure perfect gear selection in all conditions

CRANKSHAFT

The EX 450F crankshaft is key to the motor delivering great traction and enhanced rideability. It also helps give the bike its agile handling. Benefitting from long service intervals of 100 hours (who doesn’t like those?) a plain big end bearing comprising of two force-fitted bearing shells that ensure maximum reliability and durability.

CRANKCASE

Our high-pressure die cast production process guarantees two things - reliability while keeping overall crankcase weight down. Designed so that the internal moving shafts and parts are carefully positioned, the EX 450F offers best possible handling.

EXHAUST SYSTEM

Ensuring cross country specific power, our EX exhaust systems are designed to deliver the highest possible quality. The EX 250F, EX 350F and EX 450F exhaust systems are designed using an innovative 3D hydroforming process to ensure the best performance and lowest weight as well as a 2-part header pipe, which allows it to be removed without having to take out the rear shock. Further innovation allows for a short, compact silencer that doesn't increase noise levels.

DDS CLUTCH

Controlling the awesome power of the EX 450F is key! That's why the bike features a lightweight Dampened Diaphragm Steel (DSS) clutch. Using a single diaphragm steel pressure plate instead of traditional coil springs, together with a damping system the clutch delivers better traction and durability allow riders to have full and complete control.

HYDRAULIC BRAKES

Fast is fun but slowing down is essential, which is why all GASGAS motocross bikes are fitted with high quality calipers and controls. With 260mm front and 220mm rear disks, braking is easy, inspiring riders to push harder and ride faster.
* The illustrated vehicles may vary in selected details from country to country and feature either Braktec or Brembo hydraulic systems.

HYDRAULIC CLUTCH

No need for adjustment and a near maintenance-free operation, but the best thing about a hydraulic clutch is that it delivers a perfectly smooth action time and time again. With lever free-play automatically adjusted, the biting point and function of the clutch remain constant no matter if it's hot or cold.

RADIATORS

Efficient and lightweight radiators give all of our cross country bikes a low center of gravity for best possible handling and are expertly crafted using high strength aluminum. They also keep our bikes cool no matter how hard they're raced, or how challenging the super muddy, slow speed forest trails become. Integrated into the frame eliminates the need for additional hoses while the slim design of the radiators ensures a narrower bike with class-leading ergonomics.

WHEELS

Built to take a beating as well as being super-easy to take in and out when changing tires. The silver, high-strength wheels we fit to our cross country bikes are built around CNC machined hubs, using lightweight spokes and silver anodized aluminum nipples for strong and reliable construction.

TIRES

Digging into slippery grass tracks, muddy, rutted forest trails and gripping super-slick rocks and stones, Dunlop tires are standard on all GASGAS cross country bikes. Delivering top performance, long durability, and the highest levels of grip, a Dunlop MX33 tire is fitted up front with a Dunlop Geomax AT81 at the rear. The optimized tread pattern of both tires is designed to inspire confidence and improve traction and braking performance across all terrain types.

ELECTRONICS

ENGINE MANAGEMENT SYSTEM - EMS

As well as controlling the Electronic Fuel Injection (EFI) on all our 4-strokes, the Keihin EMS system also features a gear sensor, tailoring the delivery of power for each gear. Small and light, the Keihin unit is super-fast at processing engine data.

THROTTLE BODY

Our 4-stroke cross country bikes use 44mm Keihin throttle bodies , ensuring precision, smooth action and high-performance. On the EX 450F the injector is positioned to deliver the most efficient flow into the combustion chamber, guaranteeing super sharp throttle response.

ELECTRIC START AND LI-ION BATTERY

All GASGAS EX models are fitted with an E-starter, guaranteeing the one thing all cross country riders and racers want, super easy electric starting! A Li-Ion 2.0 Ah battery, which weighs approx. 1kg less than a conventional lead battery, ensures bikes conveniently fire into life each and every time while keeping overall weight down. No matter if riding conditions are super cold, or a bike has got super hot, all of our cross country models guarantee reliable starting.
