MC 125 2024

BODYWORK

All red and all-new! Fully redesigned from front to back, the sleek bodywork is incredibly ergonomic with larger contact surfaces and an improved rider triangle further enhancing control. The rad shrouds are shaped to help you better grip the bike as you get on the gas. There’s also a super grippy seat cover keeping you sat exactly where you need to be.

HANDLEBARS
Get on the gas and hold on tight! Not too tight though as nobody likes arm pump… But to make sure the ride is comfortable, Neken handlebars are clamped into redesigned bar mounts (they’re less 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.

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 toward the Twin Air filter, which helps create maximum horsepower.

FUEL TANK
The all-new fuel tank is slightly bigger when compared to the outgoing generation, but it’s still just as sleek. With an integrated fuel pump allowing the tank to be emptied further before refuelling is needed, long motos around sand tracks are definitely not a problem for this GASGAS!

FOOTPEGS
Bigger is better when it comes to footpegs, which is why on the new models there’s a bigger platform for better control. Plus, thanks to a new mounting design, they’re further inward on the frame, which makes them less prone to catching the edge of deep ruts or jump take offs, for those who like to scrub!

FRAME
A new generation bike is nothing without a new frame, right? Taking the best traits from the old frame, which if you didn’t know combined razor-sharp cornering with confidence-inspiring straight line stability, our engineering wizards have made it even better! They’ve improved the anti-squat behavior for maximum traction when exiting corners. Throughout the frame, the wall thickness has been revised in certain areas to improve rider feedback and energy absorption. Finished with a red powder coating and grippy guards to prevent wear, which provide a little extra grip for your boots too.

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.

FORGED TRIPLE CLAMPS
New, 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 smoother action, which improves front wheel feedback and leads to predictable handling on any track and any terrain. There are also new, adjustable bar mounts with a slightly larger contact area against the handlebars so if you do crash, there’s less chance of the bars twisting. A glass bead blasted finish means the triple clamps always look as good as new.

WP FORKS
Every full size GASGAS motocross model is equipped with improved 48mm WP XACT forks for 2024. Easily adjustable by hand on the outside, on the inside, they feature revised settings that specifically work with the new frame. Progressive fork action is retained thanks to the capsulated air spring and pressurized oil chamber while a new hydrostop takes the sting out of heavy landings and helps to maintain forward momentum.

WP SHOCK
Soaking up the bumps with ease, the redesigned WP XACT rear shock is shorter and lighter than the old version but still offers 300mm of travel. Inside there’s been some technical changes with a new piston improving initial comfort and helping to stay up a little higher in the stroke, especially when under hard acceleration. And just like the WP forks, the WP shock is adjustable by hand so it’s quick and easy to dial things in should you need to.

SWINGARM
Cast from one piece of aluminum, lower in weight than the old one, and slightly stiffer, the swingarm on this GASGAS is as good as it gets! There’s also a much more durable chain slider and the guide is much more rounded to help prevent catching the ground as you lay the bike over through deeply rutted turns. The swingarm is complete with a new 22mm rear wheel axle to complement the refined flex characteristics of the entire chassis. Finally, clear chain adjustment markings ensure quick and easy maintenance.

EFI
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.

CYLINDER AND PISTON
One of the biggest changes for 2024 is the introduction of EFI on the MC 125. And with this new tech, the traditional 2-stroke power valve is replaced with an innovative electronic exhaust control system. Now, the lateral exhaust ports opens slightly faster than the main exhaust port to deliver strong power and maximum reliability.

TRANSMISSION
A redesigned shift shaft drum and fork makes for even smoother shifting. As it’s made by PANKL Racing Systems, you just know that the 6-speed transmission is as good as it gets in terms of positive gear changes, reliability, and overall quality. The clever lever design helps prevent dirt build-up, too, especially when the ruts get deep and the dirt gets sticky!

CFRANKSHAFT
The magic at the heart of the motor and it’s low weight means one thing – it builds revs fast! It’s also perfectly balanced for minimal vibration and positioned to have the least amount of effect on overall handling.

CRANKCASE
Making sure the weight of the MC 125 is kept to a minimum, the thin and strong crankcases are made using a high-pressure die-cast process. Inside, the motor internals are positioned to centralize mass which leads to next level rideability. 

EXHAUST SYSTEM
Designed and developed to be slim thanks to an innovative manufacturing process, the exhaust system complies with FIM sound regulations, looks awesome, and most importantly, delivers the very best performance! The header pipe is shaped for maximum ground clearance and is fitted to a muffler that features a clever internal construction to keep noise to a minimum without sacrificing power. 

DS CLUTCH
The MC 125 is equipped with a Diaphragm Steel (DS) clutch, which is robust, super reliable, and contributes to the compact engine design. Inside the clutch basket, which is CNC machined from a single piece of steel for incredible longevity, is the clutch pack that features a single diaphragm steel pressure plate instead of traditional coil springs.

HYDRAULIC BRAKES
Fast is fun but slowing down is essential, which is why all GASGAS motocross bikes are fitted with high quality Braktec calipers and controls. With a 260mm front disk and a 220mm rear disk, both featuring a GASGAS specific design, braking performance is certainly impressive, which inspires riders to push harder, ride faster, and brake later using the redesigned lever.

HYDRAULIC CLUTCH
No need for adjustment and offering a near maintenance-free operation, the best thing about the Braktec hydraulic clutch is that it provides consistent action. With free-play at the redesigned lever automatically adjusted, the biting point and function of the clutch remain constant no matter whether the motor is started from cold or used during the heat of a battle.

RADIATORS
Keeping the motor cool is a set of strong aluminum radiators, which channel air through them in the most effective way possible. A large center tube within the frame is used to reduce the number of hoses needed and ensures a consistent flow of coolant around the motor – just what you need when you’re battling hard!

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 for complete peace of mind. 

TIRES
One of the only components carried over from the outgoing generation of GASGAS motocross bikes are the Maxxis MaxxCross MX-ST tires. Need to know why? It’s simple. They perform so well on a wide variety of terrain and they’re super-durable too. After all, who likes changing tires?

ENGINE MANAGEMENT SYSTEM
Small, light, and fast at processing data – just what you need from an engine management system! The Vitesco Technologies component is the best in the business and includes a rollover sensor that cuts the ignition during big crashes, as well as feeding information to the hour meter.

MAP SELECT SWITCH
MC 125 riders are going to love the Map Select Switch! By simply pressing a button on the bars, you can customize the power delivery so if you’re riding on hardpack and slippery tracks where there’s minimal traction, we’d suggest leaving map 1, the standard map, engaged. But if you’re riding on sand or the track is deep and muddy, activate map 2 and thank us later!

THROTTLE BODY
The MC 125 uses a 39mm Keihin throttle body with its injectors positioned to ensure the most efficient flow of fuel mixture into the combustion chamber. But what’s most important to all riders is the fact that the direct cable mounting design ensures instant throttle response.

HAPPY BUTTON
The best invention since the wheel! With an electric starter fitted, this GASGAS starts super easily every single time you hit that start button. And to simplify things further and save space on the bars, the engine stop button is located in the same housing as the start button. Using a Li-Ion battery, which weighs approx. 1kg less than a conventional lead battery, you get the convenience of electric starting while the overall bike weight is kept to a minimum. It’s a win, win for everyone!
