GASGAS EC125 2025

STYLE

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 stars falling and the going gets gnarly.​.

EXHAUST SYSTEM - Our exhaust systems, delivering specialized enduro power while adhering to competition standards, are meticulously crafted to meet FIM sound regulations. 2-stroke header pipes boast durability, optimal geometry, performance, and ground clearance, minimizing vulnerability. Advanced internal construction in 2-stroke mufflers ensures effective noise reduction and weight savings.

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.​

NEKEN HANDLEBAR, GRIPS, THROTTLE ASSEMBLY - 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. ​

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 jump allowing the tank to be emptied further before refuelling, 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, not matter how gnarly the track gets, you'll stay in complete control.​

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-aluminium subframe is light, strong, and works as one with the new frame by helping to centralise mass and contributing massively to the bike's outstanding handling characteristics ​

FORGED TRIPLE CLAMPS - Forged aluminium 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 twisiting. 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 personalised set-up, the shock can be adjusted by hand in various ways. High and low speed compression, as well as rebound can all be find-tuned quickly and easily for maximum comfort and traction.​

SWINGARM - Cast from one piece of aluminium, 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

EC 250 MOTOR - Throttle Body Injection (TBI) makes the EC 125 an absolute dream to ride! Why? Let us fill you in... The ECU continuously analyses 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. Thanks to the TBI, the EC 125 features two different motor maps. Map 1 is designed for technical terrain and hardpack surfaces while Map 2 is better suited to deep and sandy tracks. Either one can be activated by a simple press of the handlebar-mounted switch. Nice.​

CYLINDER & PISTON - One thing you won't find on the EC 125 is an old school powervalve! As the bike's fuelled using Throttle Body Injection (TBI), an innovative electronic exhaust control system is used instead. For maximum power, especially when you need it most, both the lateral exhaust port and main exhaust port open at the same time. The finishing touch to the 54mm cylinder is the machined finish on the upper contour of the exhaust port that helps deliver high-revving performance​

CRANKCASE & CRANKSHAFT - 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 centralise mass, which plays a big role in making this bike a blast to ride!​

Perfectly balanced to minimise vibration and low in weight to create a free-revving motor, the crankshaft is also positioned to have a positive effect on the bike's overall handling. As crankshafts go, our engineers have certainly designed a good one​

DS CLUTCH - Inside the EC 125 motor you'll find a Diaphragm Steel (DS) clutch that's just perfect for enduro. Robust and super reliable, it features a single diaphragm steel pressure plate instead of coil springs and it's housed inside a basket that's CNC machined from one piece of steel. It goes without saying that it's very strong and very durable. What's not to love?​

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.

PARTS​

BRAKTEC 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 aluminium, 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?​

ELECTRONICS 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.​

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 ignition. The EC 125 comes without an extra oil tank and the premix ratio is 1:40.​

MAP SELECT SWITCH - On the EC 125 the Map Select Switch is standard and thanks to the TBI, the EC 125 features two different motor maps. Map 1 is designed for technical terrain and hardpack surfaces while Map 2 is better suited to deep and sandy tracks.​​

THROTTLE BODY - For 2025, 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.​

HAPPY BUTTON - 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.​​
