At GASGAS, we absolutely love 2-strokes. So, adding our new MC 150 to our 2025 line-up was a no brainer! The motor gives riders a little bit more torque to play with when compared to our class-leading MC 125, and with our engineers knowing a thing or two about building fast dirt bikes, we've got the MC 150 dialed from the get-go. In addition to the motor, WP suspension, strong brakes, a close-ratio 6-speed gearbox, and a perfectly balanced chassis all combine to deliver one thing and one thing only - maximum performance!
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 Engine Contol Unit (ECU) to deliver the perfect mix of fuel and air. The end result? Crisp, clean running motors that create smooth, strong power.
CRANKSHAFT
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.
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.
DIAPHRAGM STEEL (DS) CLUTCH
The MC 150 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.
Fast is fun but slowing down is essential, which is why all GASGAS dirt bikes are fitted with high quality Braktec calipers and controls. Speaking of controls, a super strong rear brake pedal prevents it from getting bent out of shape in a crash or catching the ground when you're railing through a deep rut. When you combine those Braktec calipers with GASGAS specific brake disks, 260mm up front and 220mm at the rear, the result is amazing braking performance. This all means that all riders can stay on the gas longer and brake later into corners. And you know what that leads to.... faster lap times!
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.
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.
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!
All-new graphics spice things up for 2025 with the GASGAS logo emblazoned in black rather than white for a fresh twist. 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! Incredibly ergonomic with large contact surfaces to help you grip the bike with your legs, the smooth profile bodywork encourages riders to effortlessly move around on the bike and ride with a perfect technique. There's also a super grippy seat cover, in red of course, to keep you sat exactly where you need to be when you get on the gas!
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 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.
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. A strong, one-piece design for the air inlet maximizes airflow and you know what that means... maximum power! Accessing the air filter to inspect or replace it couldn't be easier, either. Simply pop the left side panel off and you'll be inside the airbox in no time.
Made from one piece of light and strong aluminum, the subframe plays an important role in creating slim ergonomics. It's also super compact too, which means it helps centralize mass, and that assists with the overall handling.
FRAME
So much testing and development went into designing and building the MC 150 frame. Just like the other GASGAS dirt bikes in our line-up, the frame makes the bike super stable at speed in addition to being able to rail around corners with ease. The frame is complete with a red powder coating and guards with a grippy surface to help you grip the bike and protect the shiny finish.
WP FORKS
Like every other full size motocross model, the MC 150 is equipped with the latest 48mm WP XACT forks. Easily adjustable by hand on the outside, on the inside, a capsulated air spring and pressurized oil chamber take care of delivering consistent damping. By using an air spring, a customized set-up can be created easily as this bike includes an air pump to adjust the pressure. And, for those who like to go big on the jumps, a hydrostop helps maintain forward momentum by taking the sting out of every heavy landing.
WP SHOCK
Soaking up the biggest of bumps with ease, the WP XACT rear shock offers no less than 300mm of travel. Low friction seals in the linkage lead to unrestricted performance from the shock and a small diameter linkage bolt keeps the overall weight low. The seals and bolt were put to the test in MXGP by Red Bull GASGAS Factory Racing, so you know they'll make a difference on track. Inside the shock, the piston has been designed to ensure maximum comfort and to help the shock stay up a little higher in the stroke, especially under hard acceleration. A customized suspension set-up can be created easily as all adjustments can be made by hand.
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
You're going to love the Map Select Switch on the MC 150! By simply pressing a button on the bars you can activate a different power delivery. So, if you're riding on hardpack and slippery tracks where there's minimal traction, we'd suggest leaving map 1, the mellow map, engaged. But, if you're riding on sand or the track is heavy going and you need an aggressive hit of power, activate map 2 and thank us later!
THROTTLE BODY
The MC 150 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.
ELECTRIC STARTER
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!
