Description
Our 'little' cross-country 4-stroke is a bike that loves to rip! Mixing smooth but strong motor performance with super agile handling and high-performance WP suspension, the EX 250F welcomes newcomers as much as it loves racing hard and chasing podiums. Delivering robust construction, smooth, torquey power and top-quality components, it's a bike any rider can have a blast on.
Style Features
- Bodywork: The new 2023 Cross Country design is very red and features the very same graphics as found on our awesome motocross bikes! Enabling riders to feel at one with their bike when darting in and out of trees, the vibrant bodywork on all GASGAS cross country bikes is also a visual expression of our Spanish personality. Considered ergonomics allow unrestricted movement while our flat, high-grip seat profile delivers comfort and control in all conditions.

Ensuring rider comfort and control thanks to optimal pressure points on rider's hands, the left side ODI grip doesn't require gluing, while on the right, the vulcanized grip features an innovative integrated throttle mechanism. With easy to adjust free-play, by changing a cam, the progression of the throttle can also be altered.
- Fuel Tank: Allowing riders to ride further and enjoy longer rides, all GASGAS cross country bikes feature 8.5-liter (2.25 gal) fuel tanks, 1.5 liters bigger than on our motocross bikes. Made from transparent polythene to allow riders to easily see how much fuel is inside the tank, a bayonet style filler cap is also used to provide a tight, reliable seal. With a specific routing keeping the external fuel line safe, all bikes are fitted with a fuel level sensor.
Handling Features
- 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.
Motor Features
- Motor: The compact motor in our EX 250F pumps out some serious performance! Amazingly powerful, weighing just 25.9kg (57 lbs) and producing peak power at 14,000rpm, the lively 250cc, electric-start power unit is incredibly user friendly yet massively capable. Compact and designed to boost handling as well as best in class performance, it's a small but potent 4-stroke package.
- Cylinder Head And Balancer Shaft: We've carefully designed the combustion chamber of the EX 250F, so it produces efficient, high-level power across the entire rev range. A motor all riders will want to rev hard, the DOHC cylinder head features large titanium valves and finger followers with a tough Diamond Like Coating (DLC) that results is minimal friction and optimal performance. To balance out the mass forces, we've also fitted a multifunctional balancer shaft, which also drives the coolant pump and the timing chain.
- Cylinder & Piston: The EX 250F cylinder and piston are both professionally engineered from high strength aluminum, performing an important role in delivering the lively performance that makes the bike so much fun to ride. Guaranteeing outstanding performance and reliability the 78mm bore houses a rigid, forged bridged-box-type piston made by CP.
- Transmission: The 6-speed forged transmission from Pankl Racing Systems ensures our little 250cc racer delivers the highest levels of durability and reliability and uses wide-ratio gearing that's perfectly suited to cross country racing. Additionally, a gear sensor allows the EMS to tailor a specific engine character to each gear. There's a no dirt gear level too!
- Crankshaft: The 6-speed forged transmission from Pankl Racing Systems ensures our little 250cc racer delivers the highest levels of durability and reliability and uses gearing that's perfectly suited to cross country racing. Additionally, a gear sensor allows the EMS to tailor a specific engine character to each gear. There's a no dirt gear level too!
- Crankcase: The protective housing that keeps all internal components safe and secure and in the perfect positions to achieve the ideal center of gravity, the high-pressure casting process we use to make our crankcases ensures they have a thin wall thickness for minimal weight. Don't worry, they are seriously strong!
- 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.
- DS Clutch: The fitted Diaphragm Steel (DS) clutch ensures that riders can quickly and easily keep the revs up on the EX 250F. Featuring a single diaphragm steel pressure plate instead of traditional coil springs the clutch basket is a single-piece CNC machined steel component, which allows the use of thin steel liners. Light and precise the clutch ensures a smooth and constant action no matter how much abuse it receives!
Parts Features
- Brakes: From high-speed straightaways to technical forest single tracks, our Brembo brake calipers and high-performance 260mm front and 220mm rear discs deliver impressive stopping power and an all-important smooth, controllable action.
- Brembo Hydraulic Clutch: The Brembo hydraulic clutch fitted to all GASGAS cross country bikes gives a super smooth action and a consistent biting point no matter how long, or hard, or hot or cold, a ride is. With play constantly adjusted so that the function remains consistent the light action also minimizes rider tiredness.
- 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 Features
- 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 250F the injector is positioned to deliver the most efficient flow into the combustion chamber, guaranteeing super sharp throttle response.
