2025 GASGAS EC 250

Electronics

• ENGINE MANAGEMENT SYSTEM (EMS): All GASGAS EC 2-stroke models feature the most advanced Engine Management System (EMS) of any 2-stroke enduro bike out there, which means riders can fully focus on the trails ahead. The brain of the system is the Electronic Control Unit (ECU), which engages a different map for each gear to give the very best performance as well as a Rollover Sensor which stops the motor in the event of a heavy fall. Put simply, by controlling the ignition timing and the amount of fuel injected, using sensor data such as intake air pressure, throttle position, and coolant temperature, the EMS takes care of everything related to fuel, air, and oil.
• LED LIGHT: By using LEDs to light the way, the headlight is almost three times brighter than a traditional bulb and is particularly effective when you're deep into dense woodland. And should either the mask or headlight get damaged, the two-piece design lets you replace only what's broken.
• MAP SELECT SWITCH: Sometimes in enduro, you'll want a different style of power delivery depending on the terrain or situation. This is where our redesigned Map Select Switch, which is available from your local GASGAS dealer, steps in. Easy to fit and offering two maps, Map 1 is super mellow and perfect for slow, technical sections. But when it comes to deep mud and softer track conditions where you need direct response, engage Map 2 and thank us later!
• THROTTLE BODY: For 2025, our 2-stroke motors are fueled using Throttle Body Injection - a 39mm Keihin throttle body, to be precise - which works together with the ECU to deliver the perfect mix of fuel and air. The end result? Crisp, clean running motors that create smooth, strong power.
• ELECTRIC STARTER: To simplify starting and stopping, we've now put the buttons for each function into the same housing on the right-hand side of the bars. The starter motor itself is powered by a lightweight, Li-lon battery that fires this GASGAS into life as soon as you hit that start button. It's fast and reliable. Just what you want from an electric start, really.

Handling

• FRAME: Do you want an enduro bike that offers playful handling, razor-sharp cornering, and confidence-inspiring straight-line stability? Who doesn't, right? Well, fortunately, for everyone who throws a leg over a GASGAS enduro bike, this is exactly what you'll expect thanks to some seriously clever work by the engineers who designed the frame. This bike really does handle like a dream, which reduces fatigue and, in turn, extends the fun! You're gonna love it. Grippy frame guards just above the footpegs provide a little extra grip for your boots for maximum control, even when the conditions get gnarly!
• SUBFRAME: The all-aluminum subframe is light, strong, and works as one with the new frame by helping to centralize 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: Up front, WP XPLOR Open Cartridge forks take care of soaking up the bumps with ease. Speaking of things being easy, adjusting the forks' set-up to suit your speed, weight, and style couldn't be any simpler. On top of the left fork leg you can dial in the compression while over on the right fork leg you can fine tune the rebound, with both settings adjustable by hand. So, so, easy!
• WP SHOCK: Continuing to offer 300mm of travel, the performance of the WP XACT rear shock is taken up a notch for 2025 thanks to the new, lower friction seals in the linkage while a smaller diameter linkage bolt saves a little weight. Making sure every rider can create a personalized set-up, the shock can be adjusted by hand in various ways. High and low speed compression, as well as rebound can all be fine-tuned quickly and easily for maximum comfort and traction.
• SWINGARM: Cast from one piece of aluminum, the swingarm on this GASGAS certainly looks the business! A new, stronger chain slider improves durability and keeps the chain running smoother for longer. 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): Throttle Body Injection (TBI) makes the EC 250 an absolute dream to ride! Why? Let us fill you in... While you're riding, the ECU continuously analyzes the air and water temperature, crankcase pressure, RPM, and the position of the throttle. What this means is that the perfect mix of air and fuel is delivered into the motor at all times, so it runs clean and offers maximum power when you get on the gas.
• MOTOR: For decades the 250cc 2-stroke has been the choice of enduro riders and racers across the world as it offers the best combination of strong power within a lightweight package. For 2024, the new, 6-speed EC 250 motor delivers incredible performance thanks to throttle body injection, an enduro specific transmission, and a super-durable clutch. This new motor makes the EC 250 so easy to ride and it's just as easy to maintain. You're going to love it!
• CYLINDER & PISTON: One thing you won't find on the EC 250 is an old school powervalve! As the bike's fueled using Throttle Body Injection (TBI), an electronic exhaust control system is used instead, and it works by opening the lateral exhaust ports before the main exhaust port opens. What does this mean? Well, it creates a smooth, strong, and very rideable power delivery that all enduro riders will love out on the trails.
• TRANSMISSION: A wide ratio, 6-speed, enduro-specific transmission lets you attack the terrain and every obstacle with confidence. It's also smooth shifting and super durable, with every gear change positive in all conditions, thanks in part to the gear lever that's designed to prevent mud from building up around it.
• CRANKSHAFT: Engineered to be just the right weight and to create a lively response from the motor without sacrificing torque, the EC 250 crankshaft is perfectly balanced. This means less vibration from the motor, which is reduced even further thanks to the counter balancer shaft. The end result is less fatigue and therefore, more comfort, which means you can ride for longer. Just what you want when it comes to enduro!
• CRANKCASE: Low in weight and super-strong, the crankcases have a thin-wall design that was made possible by using a high-pressure, die-cast production process. Within the crankcases, all moving parts are positioned to centralize mass, which plays a big role in making this bike a blast to ride!
• COUNTER BALANCER SHAFT: The EC 250 motor houses a laterally mounted counter balancer shaft to significantly reduce vibration. The result? More comfort, which you'll definitely benefit from during longer and more technical rides.
• EXHAUST SYSTEM: Delivering enduro specific power as well as being competition-compliant, all our exhausts are designed and built to meet FIM sound regulations! Our 2-stroke header pipes are super strong and offer optimal geometry, performance, and ground clearance, making them less susceptible to damage. The 2-stroke mufflers also feature an advanced internal construction for excellent noise damping and weight saving.
• DDS CLUTCH: Stop, start. Stop, start. We know what it's like sometimes, which is why the EC 250 has a super light clutch action. We fit a Damped Diaphragm Steel (DDS) clutch and BRAKTEC hydraulic system to our GASGAS EC 250, which creates a clutch that has a light and consistent action and is almost maintenance free. With a single diaphragm spring instead of using the more common coil springs, the design also incorporates a damping system, which increases both traction and durability.

Parts

• BRAKES: Fast is fun but quite often in enduro, you'll need to slow down in a real hurry! This is precisely why all GASGAS enduro bikes are fitted with the latest high quality BRAKTEC brake calipers and controls. With a 260mm disk up front and a 220mm disk at the rear, braking performance is seriously impressive, which inspires riders to push harder, ride faster, and brake later.
• HYDRAULIC CLUTCH: When riding enduro, you know full well that you'll need consistent clutch performance, especially when working your way through the toughest of technical sections. So, it's for this very reason that all GASGAS enduro bikes are fitted with a quality BRAKTEC hydraulic clutch system. In addition to the lever being extremely light to pull in, which reduces fatigue, the free play of the system is also self-adjusting. This means the biting point from the moment you fire your GASGAS into life remains the same all day. Every day.
• RADIATORS: A cool running motor is a well performing motor, which is why all GASGAS enduro bikes feature a cooling system designed for maximum efficiency. It also eliminates the need for additional hoses while the slim design of the radiators ensures a narrower bike with class-leading ergonomics. Expertly crafted using high strength aluminum, the radiators are mounted close to the center of gravity for the best possible handling.
• 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 and durability for complete peace of mind.
• TIRES: One of the only components carried over from the outgoing generation of GASGAS enduro bikes are the Dunlop tires. Need to know why? Because they work so well on a wide variety of terrain and they're super-durable too. After all, who likes changing tires?
• OIL TANK & PUMP: No need for premixing here! Running at an average fuel-to-oil ratio of 60:1 means one tank of oil is enough for hours and hours of riding. Controlled by the Engine Management System, an electronic oil pump feeds oil into the throttle body based on how hard the motor is working so you can be confident that no matter how hard this thing's revving, the motor is always perfectly lubricated. Additionally, when the oil level is getting low, a warning light illuminates so you'll know exactly when it's time to add a little more oil.

Style

• GRAPHICS: All-new graphics spice things up for 2025! 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.
• BODYWORK: All red, front to back! Just the way a GASGAS should be. Incredibly ergonomic with large contact surfaces to help you grip the bike with your legs, the smooth profile bodywork encourages riders to move around and ride with a perfect technique. There's also a super grippy seat cover to keep you locked in place, which works just as well when the rain starts falling and the going gets gnarly!
• HANDLEBARS: Get on the gas and hold on tight! Not too tight though as nobody likes arm pump... But to make sure the riding is comfortable, NEKEN handlebars are clamped into redesigned bar mounts (they're 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 all riders. There's also a new, stronger throttle housing that's more impact resistant for improved durability.
• 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, which helps create maximum horsepower.
• FUEL TANK: Super slim and made from transparent polythene, the fuel tank lets you see how much fuel is inside while a threaded filler cap provides a secure and reliable seal. Beneath the fuel tank is a stronger support made from rubber that not only helps hold the tank firmly in place but protects the frame from wear as well. With an integrated fuel pump allowing the tank to be emptied further before refueling, extended rides are not 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.
