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 and Throttle Body Injection make long days in the dirt as good as it gets. You're gonna love it!

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.

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-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!

motor

MOTOR

We don't want to brag, but everything about the ES 350 motor is pretty awesome! Designed to be fast, of course, it's also pretty low in weight. Inside, all major components are positioned to centralize mass. This helps with the overall handling of the bike so like we said, the motor is pretty awesome!

CRANKSHAFT

Buried deep inside the ES 350 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 ES 350 offers long, 135-hour crankshaft service intervals.

CYLINDER & 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.

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.

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.

electronics

ENGINE MANAGEMENT SYSTEM (EMS)

Small, light, and fast at processing data! The Engine Management System (EMS) is constantly measuring, calculating, and optimizing how the motor is running and adjusts accordingly, which means you can just 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!

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.

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!

THROTTLE BODY

We use a 42mm Keihin unit on the ES 350, and 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.
