EX 250F
STYLE
BODYWORK
All red and all-new! 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 all-new 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 moto's 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 new models there's a bigger platform for better control. Plus, thanks to a new 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!
HANDLING
FRAME
A new generation bike is nothing without a new 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-aluminium subframe is light, strong, and works as one with the new frame by helping to centralizing mass and contributing massively to the bike's outstanding handling characteristics.
FORGED TRIPLE CLAMPS
New, 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 also new, 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 all-new, 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 new 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 new 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
It was awesome before but our engineers have made the 250cc 4-stroke motor even better! More compact and lighter, the motor is tilted two degrees backwards in the frame to centralize mass for improved handling and you'll notice these changes as soon as you start picking up the pace on the race track. The motor's new position also lowers the sprocket by 3mm which improve's the bike's behaviour, especially under acceleration, as it holds up the rear end for better stability.
CYLINDER HEAD
There's a lot packed into this DOHC cylinder head! Designed to simply deliver the best performance possible, larger titanium exhaust valves, Diamond-like Carbon coated finger followers, and a better sealing head gasket means you can twist the throttle to your heart's content! This bike revs freely up to its 14,000rpm limit and produces some seriously strong power along the way.
CYLINDER & PISTON
Performing an important role in delivering the lively performance that makes the EX 250F so much fun to ride, both the cylinder and forged bridged-box-type CP piston are professionally engineered from high strength aluminum. The larger 81mm bore helps bump up the compression to 14.5:1 and you know what that means - more torque and more peak power!
TRANSMISSION
Made by PANKL Racing Systems, the new transmission has a redesigned shift shaft and a low-friction coating on the internal shifting fork for improved gear changes, even when upshifting when the motor's under heavy load. Still light and durable, it's never been easier to flick through the six-speed transmission on the EX 250F. Also, a clever lever design helps prevent dirt build-up, especially when the ruts get deep and the dirt gets sticky!
CRANKSHAFT
Up and down, round and round... life's tough being a 250F crankshaft! So it's a good job that the spinning heart of the EX 250F motor is super durable with service intervals of 90 hours. Not only designed for maximum performance, but the crankshaft is positioned to help centralize oscillating masses, which creates a super agile and lightweight feel to the bike while riding.
CRANKCASE
The protective housing 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
The EX 250F is equipped with a Diaphragm Steel (DS) clutch, which is robust, super reliable, and contributes to the compact engine design. Inside the clutch basket, which is CNC machined from a single piece of steel for incredible longevity, is the clutch pack that features a single diaphragm steel pressure plate instead of traditional coil springs.
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 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 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?
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 customised 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 250F 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!
