2026 GASGAS EX 300 for Sale

Electronics

• ENGINE MANAGEMENT SYSTEM (EMS): Small, light, and fast at processing data - just what you need from an engine management system! The Vitesco 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.
• MAP SELECT SWITCH: Ignite your GASGAS dirt bike's potential with the optional Map Select Switch. This essential Technical Accessory provides two dynamic maps (MELLOW/ AGGRESSIVE), allowing you to unleash a more direct throttle response with the second map. Upgrade your GASGAS experience with the Map Select Switch and take the upper hand in the off-road game.
• THROTTLE BODY: The EX 300 uses a 39mm Keihin throttle body with its injectors 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 design ensures instant throttle response.
• OFFROAD CONTROL UNIT: Simplifying everything electrical, the Offroad Control Unit replaces all the old school relays and fuses. You'll find the OCU under the seat to keep it safe and sound and in the unlikely event that an electrical component on the bike registers a problem, a corresponding LED changes from green to red. This way, you can quickly diagnose the issue, get it sorted, then get back to riding!
• ELECTRIC STARTER: 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. 2.2lb (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!

Handling

• FRAME: The current frame hits the sweet spot between razor-sharp handling and just the right amount of flex. Lightweight motor mounts dial in the feel without messing with straight-line stability, and smart material tweaks, like a slimmed-down upper shock mount and reduced wall thickness up front, save 300g. Developed with the GASGAS Factory Racing crew, it's a setup that stays planted and lets you push harder in every turn with a big smile in your face.
• SUBFRAME: The all-aluminum subframe is light, strong, and works as one with the mainframe by helping to centralizing mass and contributing massively to the bike's outstanding handling characteristics.
• TRIPLE CLAMPS: 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 smooth action, which improves front wheel feedback and leads to predictable handling on any track and any terrain. The adjustable bar mounts with the slightly larger contact area against the handlebars reduce the chance of the bars twisting. A glass bead blasted finish means the triple clamps always look as good as new.
• WP FORKS: The EX 300 features 48mm WP XACT closed cartridge forks as they're just so good. Easily adjustable by hand on the outside, on the inside the latest technology prevents the oil from 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: With no less than 300mm of travel, the WP XACT rear shock effortlessly absorbs even the biggest bumps. While the shock remains the same, it continues to deliver top-tier performance, thanks to years of development and feedback from the factory race team. The settings are fine-tuned to work perfectly with the frame, offering optimal damping straight from the showroom floor. And adjusting your set-up? It's still quick and easy with simple hand adjustments, giving you full control to dial it in.
• SWINGARM: Cast from one piece of aluminum, the swingarm on this GASGAS certainly looks the business! A strong chain slider ensures durability and keeps the chain running smooth for long time. At the rear of the swingarm you'll find a chain guide with a rounded profile to help it glide over the ground as you lay the bike over through deeply rutted turns. Finally, clear chain adjustment markings ensure quick and easy maintenance.

Motor

• ELECTRONIC FUEL INJECTION (EFI): The motor that does it all! It doesn't matter if you short shift or hang onto every gear, the revitalized EX 300 motor, with added fuel injection, separates this bike ever further from the competition with its delivery of usable torque down low and high-revving peak power up top. And it's those who ride wide open that will benefit the most from the counter balancer shaft inside the motor as it keeps vibration to an absolute minimum. A protective cap for the fuel connector adds durability and keeps dirt out, ensuring reliable performance even in the harshest conditions.
• CYLINDER & PISTON: We don't bother with a traditional, old-school powervalve on our cross country bikes. Instead, we use an electronic exhaust control system to help deliver the power. Introduced last year to take rideability to an even higher level, this cutting-edge technology really works.
• TRANSMISSION: Delivering quality, durability, and reliability, the 6-speed transmission by PANKL Racing Systems is built tough, and ensures easy and accurate gear shifting no matter how gnarly the conditions. The lever is cleverly designed to prevent dirt build-up, which is particularly effective when the ruts get deep and the dirt gets sticky!
• CRANKSHAFT: The magic at the heart of the motor and its low weight means one thing - it revs fast! It's also perfectly balanced for minimal vibration and positioned to have the least amount of effect on overall handling.
• CRANKCASE: Making sure the weight of the EX 300 is kept to a minimum, the thin and strong crankcases are made using a high-pressure die cast process. Inside, the motor internals are positioned to centralize mass, which leads to next level rideability.
• DIAPHRAGM STEEL (DS) CLUTCH: Inside the EX 300 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.

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. Speaking of controls, the rear brake pedal is now considerably stronger to prevent it from getting bent out of shape in a crash or catching the ground when you're railing through a deep rut. When you combine those BRAKTEC calipers with GASGAS specific brake disks, 260mm up front and 220mm at the rear, the end result is amazing braking performance. This all means that all riders can stay on the gas longer and brake later into corners. And we all know what that leads to... faster lap times!
• 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 center 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 black, CNC machined hubs, lightweight spokes, and high-strength rims deliver maximum strength for complete peace of mind.
• TIRES: Grip you can trust! Fitted with Dunlop Geomax AT82 tires front and rear our TX 300 is ready to rip across any terrain. The trusted compound boosts traction when it counts, while both tires deliver the durability and performance you need to stay on the gas longer. Proven, reliable, and built for serious offroad fun.

Style

• GRAPHICS: Black graphic details bring a bold twist to the signature GASGAS red, with a clean white logo that pops right off the dark background. Other blacked-out parts like the seat cover, handlebar, and rims dial up the style to really set things off. Thanks to durable IML technology, the graphics are built into the bodywork to keep your GASGAS looking sharp, ride after ride.
• BODYWORK: Proudly red, with sharp black details! Incredibly ergonomic with large contact surfaces to help you grip the bike with your legs, the smooth profile bodywork encourages riders to effortlessly move around on the bike and ride with a perfect technique. There's also a super grippy seat cover, now in black, to keep you sat exactly where you need to be when you get on the gas!
• HANDLEBARS: Neken handlebars are now black and clamped into redesigned bar mounts (which are more 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. A black and red bar pad adds style and safety.
• 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. With a stronger one-piece design for the air intake, maximum airflow is guaranteed, and you know what that means... maximum power! Like before, accessing the air filter to inspect or replace it couldn't be easier. Simply pop the left side panel off and you'll be inside the airbox in no time.
• FUEL TANK: The fuel tank sits neatly inside the vibrant red bodywork and a beefie rubber tank support underneath helps hold it firmly in place while protecting the frame from wear. With an integrated fuel pump inside the tank, long races around deep sand tracks aren't a problem for this GASGAS!
• FOOTPEGS: Bigger is better when it comes to footpegs. That's precisely why they not only have a larger surface area for maximum grip, but we've also made them less likely to catch on the edges of deep ruts, which mean no loss to forward momentum. The pegs are also light and prevent mud from building up. So, no matter how gnarly the track gets, you'll stay in complete control.
