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!

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.
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.
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. With a stronger one-piece design for the air intake in 2025, maximum airflow is guaranteed, and you know what that means... maximum power! Like before, accessing the air filter to inspect or replace it couldn't be easier. Simply pop the left side panel off and you'll be inside the airbox in no time.
The fuel tank sits neatly inside the vibrant red bodywork and for 2025 a beefier rubber tank support underneath helps hold it firmly in place while protecting the frame from wear. With an integrated fuel pump inside the tank allowing for it to be emptied further, long motos around deep sand tracks aren't a problem for this GASGAS!
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.
So much testing and development went into designing and building the frame last year, but our engineers have worked on refining things even further! Thanks to brand new, lighter, motor mounts, the flex characteristics of the frame are improved without any sacrifice to straight-line stability. Around the upper shock mount a little material has been removed while the wall thickness at the front of the frame is also slightly reduced, saving 300g. With all these revisions, which were tested by Red Bull GASGAS Factory Racing in MXGP, the bike is now much more settled through every corner.
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 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 twisting. A glass bead blasted finish means the triple clamps always look as good as new.
Updated frames for every GASGAS motocross model in 2025 means new settings for the 48mm, split air WP XACT forks. Continuing to be easily adjustable by hand on the outside, on the inside, a capsulated air spring and pressurised oil chamber take care of delivering consistent damping. By using an air spring, a customised 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 in the forks help maintain forward momentum by taking the sting out of every heavy landing.
With no less than 300mm of travel, the WP XACT rear shock soaks up the biggest of bumps with ease. For 2025, the performance of the shock is taken up a notch thanks to the new, lower friction seals in the linkage and a smaller diameter linkage bolt, to reduce a little weight. Both revisions were put to the test in MXGP, so you know they'll make a difference. Because of the new frame, the shock's settings have been revised to deliver the best damping straight from the showroom floor. However, creating a customised set-up remains super simple as adjustments can still be made quickly by hand.
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
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.
CYLINDER & PISTON - With the introduction of the Electronic Fuel Injection (EFI) on the MC 150, 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 Upgrades: A redesigned shift shaft drum and fork enhance gear shifting's fluidity. With PANKL Racing Systems manufacturing, the 6-speed transmission guarantees exceptional gear changes, reliability, and quality. Its smart lever design combats dirt accumulation, particularly in challenging conditions.
Crankshaft Innovation: The engine's core, the crankshaft, is lightweight, enabling quick rev-building. Its meticulous balance minimizes vibration, strategically positioned for minimal impact on overall handling.
Crankcase Optimisation: To maintain the MC 150's agility, thin yet sturdy crankcases are forged through high-pressure die-casting. Internally, optimal mass centralisation enhances rideability.
Exhaust System Excellence: Slim and FIM sound regulation-compliant, the exhaust system excels in performance. The header pipe's design prioritizes ground clearance, connecting to a muffler with noise-reducing construction that preserves power.
DS Clutch Performance: The MC 150 employs a robust and reliable Diaphragm Steel (DS) clutch, contributing to the compact engine design. Inside the CNC-machined steel clutch basket is a single diaphragm steel pressure plate, replacing traditional coil springs for longevity and efficiency.
