Overview

Powerful. Playful. Energetic. Yeah, our EX 300 is quite the bike! It may be a big-bore 2-stroke but it's an absolute dream to ride thanks to the electronical exhaust control helping to deliver a really usable spread of power. Short shift it and ride the wave of the torque curve or ride it hard and rail every berm in sight. The choice is yours. An updated frame for 2025 keeps things stable at speed and makes cornering even easier than ever before. It goes without saying, but our EX 300 is super versatile and an absolute blast to ride!

motor

2025 GASGAS EX 300 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 it's 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.


 

2025 GASGAS EX 300 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.

2025 GASGAS EX 300 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!

2025 GASGAS EX 300DIAPHRAGM STEEL (DS) CLUTCH

Inside the EX 250 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.

2025 GASGAS EX 300 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!

2025 GASGAS EX 300 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.

2025 GASGAS EX 300 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. 

2025 GASGAS EX 300RADIATORS

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!
style

2025 GASGAS EX 300GRAPHICS

All-new graphics spice things up for 2025 with the GASGAS logo emblazoned in black rather than white for a fresh twist. Still red, still durable, and still eye-catching, the distinctive design is applied using IML technology. This means they're applied within the bodywork so your GASGAS will stay looking super fresh for a long, long time, even if you ride in gnarly conditions week after week.

2025 GASGAS EX 300 BODYWORK

All red, front to back! 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, in red of course, to keep you sat exactly where you need to be when you get on the gas!

2025 GASGAS EX 300 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.

2025 GASGAS EX 300AIRBOX

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 in 2025, 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.

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.

2025 GASGAS EX 300 FRAME

So much testing and development went into designing and building the frame last year, but our engineers have worked on refining things even further! Thanks to brand new, lighter, motor mounts, the flex characteristics of the frame are improved without any sacrifice to straight-line stability. Around the upper shock mount a little material has been removed while the wall thickness at the front of the frame is also slightly reduced, saving 300g. With all these revisions the bike is now much more settled through every corner.

2025 GASGAS EX 300 WP FORKS

Every GASGAS cross country bike features 48mm WP XACT closed cartridge forks as they're just so damn 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.

2025 GASGAS EX 300WP SHOCK

With no less than 300mm of travel, the WP XACT rear shock soaks up the biggest of bumps with ease. For 2025, the performance of the shock is taken up a notch thanks to the new, lower friction seals in the linkage and a smaller diameter linkage bolt, to reduce a little weight. Both revisions were put to the test in MXGP, so you know they'll make a difference. Because of the new frame, the shock's settings have been revised to deliver the best damping straight from the showroom floor. However, creating a customized set-up remains super simple as adjustments can still be made quickly by hand.
electronics

2025 GASGAS EX 300 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.

2025 GASGAS EX 300 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.

2025 GASGAS EX 300 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.

2025 GASGAS EX 300ELECTRIC 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. 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!
