EC 350F 2025

Put simply, our awesome EC 350F is the ultimate, do-it-all enduro bike. Equally capable on both technical terrain and faster going, this powerful mid-size 4-stroke has it all going on. An updated frame for 2025 further elevates the already incredible riding experience by making the approach into turns feel even more settled than before. What this means is that you can get in and out of corners faster with less effort. Easily adjustable and supple WP suspension takes comfort and finding traction to unrivalled levels while the smooth-shifting 6-speed transmission, Throttle Body Injection, and multiple electronic rider aids make long days in the dirt as good as it gets. You’re gonna love it!

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.

SUBFRAME
The all-aluminium 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.

CYLINDER AND PISTON
Engineered for performance, the cylinder and bridged-box-type CP piston combine to create impressive torque and peak power. And with both components professionally engineered from high strength aluminum, you can be assured that reliability is never in question.

CYLINDER HEAD
It’s the magic that happens inside the DOHC cylinder head that guarantees the EC 350F produces high-revving power across its entire rev range. Large exhaust valves allow the motor to breathe easy while the finger followers are treated with a Diamond-Like Carbon (DLC) coating for minimal friction. And minimal friction equates to maximum performance!

COUNTER BALANCER SHAFT
The EC 350F motor uses a compact, multifunctional counter balancer shaft to counteract the rotational force of the crankshaft. Reducing any unwanted vibrations, it also drives the water pump and timing chain. 

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
Buried deep inside the EC 350F motor, the crankshaft is key to driving the extremely high-speed moving parts inside the engine, which in turn unleash the motor’s unrivalled power. Additionally, thanks to an oil feed that ensures enhanced engine durability, the EC 350F offers long, 135-hour crankshaft service intervals.

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!

EXHASUT SYSTEM
Delivering enduro specific power as well as being competition-compliant, all our exhausts are designed and built to meet FIM sound regulations! Our 4-stroke header pipes wrap tightly around the motor to keep them out of harms way and deliver the very best performance at the lowest possible weight. They’re also made in two pieces, which means they can easily be removed without needing to take out the rear shock. At the rear, there’s short and compact silencer made from aluminum with a raw finish because, lets face it, it’s going to get scratched sooner or later!

DDS CLUTCH
Using a compact design to deliver better action and improved durability, the EC 350F uses a Dampened Diaphragm Steel (DDS) clutch, together with a hydraulic BRAKTEC system. Ensuring riders have total control at all times, a single diaphragm steel pressure plate is used instead of traditional coil springs, which together with a damping system delivers better traction and durability.

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 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?

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 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.

THROTTLE BODY
We use a 42mm Keihin unit on our 4-strokes enduro bikes. On the EC 350F, 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.

OFFROAD CONTROL UNIT (OCU)
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!

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.
