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 AND PISTON
All-new, Throttle Body Injection means the cylinder now features an electronic exhaust control system, which opens the lateral exhaust ports before the main exhaust port opens. The result? A smoother and stronger power delivery with a better connection between the throttle and rear wheel.
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 definitly beneft from during longer and more technical rides.
Low in weight and super-strong, the new crankcases have a thin-wall design that is 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!
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!
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.
A new, enduro-specific, 6-speed wide-ratio Pankl Racing Systems transmission is super durable and reliable and allows you to take on both the slowest and fastest types of terrain in total confidence. The transmission is now even easier to shift thanks to a few refinements to the shifting mechanism while a new gear lever prevents dirt from building up.
OIL TANK AND 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.
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.
BRAKTEC HYDRAULIC CLUTCH
The Braktec hydraulic clutch system we fit to all GASGAS enduro bikes provides even wear, near maintenance-free operation, and perfect action - even in the toughest of enduro conditions. It's also extremely light, which means less fatigue, especially through technical sections. Free play is constantly adjusted to ensure the biting point never changes and for 2024, there's a redesigned lever for a little bit more comfort.
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.
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.
One of the only components carried over from the outgoing generation of GASGAS enduro bikes are the Maxxis MaxxEnduro 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?
Rounding out the changes to the updated bodywork is the all-new LED headlight. Brighter by almost 3 times, it really lights the way when day turns to night. And should either the mask or light get damaged, the new two-piece design lets you replace only what's broken.
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.
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!
For 2024, our 2-stroke motors are fuelled 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.
The best invention since the wheel! With an electric starter fitted, this GASGAS starts super easily every single time you hit that start button. Using a Li-Ion battery, which weighs approx. 1kg less than a conventional lead battery, we can offer the convenience of electric starting while also keeping overall bike weight to a minimum. It's a win, win for everyone!
