Everything about the EC 250F motor is all new for 2024. Making the already awesome motor even better, our engineers have made it lighter and faster by refining all major components to maximise power and torque. It even helps to improve handling as it's positioned inside the frame tilting backwards slightly, to help centralize mass.
CYLINDER AND PISTON
Another thing that's completely new for 2024 is the cylinder and CP piston. The cylinder bore is now wider at 81mm with the stroke adapted to 48.5mm. What does this mean, exactly? Put simply, the compression ratio is bumped up to 14.4:1 and the end result is a noticeable boost to torque and peak power.
It's the magic that happens inside the fully redesigned DOHC cylinder head that guarantees the EC 250F produces efficient, high-revving power across the entire rev range. Larger exhaust valves allow the motor to breathe more easily for 2024 and with the finger followers treated with a Diamond-Like Carbon (DLC) coating, minimal friction equates to maximum performance.
COUNTER BALANCER SHAFT
In order to counteract the rotational force of the crankshaft and reduce vibration, the EC 250F motor uses a multifunctional counter balancer shaft that also drives the water pump and timing chain.
Low in weight and super-strong, the new crankcases have a thin-wall design, which is made possible by using a high-pressure die cast production process. Within the crankcases, all moving parts are positioned to centralize mass. This plays a big role in making the bike a blast to ride!
Specifically positioned within the motor, the EC 250F crankshaft helps centralize oscillating masses for super easy handling. A plain big end bearing with force-fitted bearing shells increase service intervals, ensuring durability and the best possible performance. Plain big end bearings with force-fitted bearing shells ensure 135-hour service intervals!
Ensuring riders have precise control over the EC 250F at all times, we use a Dampened Diaphragm Steel (DDS) clutch. Using a single diaphragm steel pressure plate instead of traditional coil springs, together with a damping system the clutch delivers better traction and durability. We use a Braktec hydraulic master cylinder to ensure a smooth, progressive lever action.
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.
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
Small, light, and fast at processing data! The Engine Management System is constantly measuring, calculating, and optimizing how the motor is running and adjusts accordingly, which means you can focus on the trail ahead. After all, that's what enduro is all about, right? Plus, as crashes are part and parcel of riding offroad, there's a new rollover sensor that stops the motor if the bike goes upside down, which in enduro can, and often does, happen!
We use a 42mm Keihin unit on our 4-strokes enduro bikes. On the EC 250F, immediate throttle response is guaranteed due to the throttle cable being mounted directly without using a linkage. Additionally, the throttle body injector is positioned to deliver the most efficient flow into the combustion chamber, which ensures the very best performance.
MAP SELECT SWITCH
Sometimes in enduro, you'll want a different style of power delivery, depending on the terrain or just because you like to set your bike up a certain way. Our redesigned Map Select Switch, available now from your local GASGAS dealer, makes that possible. Offering Traction Control for maximum grip on slippery terrain, there's also the Quickshifter that makes sure you never miss an all-important upshift. Plus, there're two maps to choose from. Map 1 is mellow, and Map 2 is more direct. The Map Select Switch is super easy to fit and really spices up enduro for riders of all abilities.
Simplifying everything electrical, the new 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!
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!
