MC 350F 2022

Our new MC 350F strikes the perfect balance between playful 250-like agility and dirt-ripping 450-like torque. This amazing performance is enhanced by innovative technology and next-level features to make the MC 350F a competitive but friendly platform for racers and riders of all types. Looking for the right mix of power and fun? Look no further!
Red with a splash of white. That’s the way we like it! The bodywork fitted to all GASGAS motocross bikes not only reflects our vibrant, Spanish personality but also ensures complete harmony between rider and bike. Considered ergonomics allow unrestricted movement while our flat, high-grip seat profile delivers comfort and control in all conditions.
Less time working on bikes means more time riding bikes, which is exactly why you’ll love the straightforward, no tools needed filter mounting system on all GASGAS motocross bikes. Allowing quick and easy filter changes, the airbox is designed with precisely positioned inlet ducts that ensure maximum airflow and protection of the Twin Air filter.
Hold on, it’s important! We fit all GASGAS motocross bikes with quality Neken tapered handlebars, guaranteeing comfort and control thanks to optimal pressure points on rider’s hands. The left side ODI grip doesn’t require gluing, while on the right, the vulcanized grip features an innovative integrated throttle mechanism. With easy to adjust free-play, by changing a cam, the progression of the throttle can also be altered.
We like to keep our fuel tanks simple and robust, that’s why we opted for a threaded filler cap that provides a tight and reliable seal and positioned the external fuel line to make sure it’s less exposed and susceptible to damage. The black 7-litre lightweight polythene fuel tanks feature direct internal line routing from the pump to the flange, for optimal fuel flow.
The technology in our frames ensures riders enjoy playful handling and an energetic feeling on any motocross tracks. Underneath the red powder coating there’s a lightweight chromium molybdenum steel, hydro-formed, laser-cut and robot-welded chassis that’s built to perform. Designed to be rigid where it needs to be rigid and to flex where flex is needed, it provides exceptional rider feedback, energy absorption and straight-line stability.
With a short and compact profile all GASGAS motocross subframes are made from lightweight aluminum. The profile helps centralize mass while also keeping weight down.
Featuring a 3-way handlebar adjustment that allows riders to set-up the front-end of their bikes just the way they like it, the forged, 22mm offset triple clamps work in harmony with our WP front forks to help deliver precise handling and stability. 
All GASGAS motocross models are equipped with advanced, super-lightweight 48mm WP XACT upside-down forks that are easily adjustable. Delivering progressive and consistent damping no matter how rough the track, they feature a capsulated air spring and pressurized oil chamber together with other internal damping wizardry. The end result is outstanding rider comfort and front-end confidence.
Traction is what it’s all about and our fully adjustable WP XACT rear shock provides the advanced damping that inspires confidence and ignites fun. Designed to work harmoniously with both frame and swingarm to offer incredible energy absorption, the shock is also matched to a linkage system with a specific geometry that further aids traction. Rebound and high/low speed compression adjustment and 300mm of travel means GASGAS motocross bikes are ready to take on the roughest tracks.
Light, strong and featuring visible chain adjustment marks to make life at the track easier, our motocross swingarms are made using a gravity die-cast process to guarantee durability and precision.
The 350cc DOHC motor pumps out free-revving power on demand. That’s all thanks to clever manufacturing that allows 58hp to be squeezed from the 27.2kg power unit when revved at 13,400 rpm. As well as its awesome power, the compact design with centralized oscillating masses also improves the overall handling of the bike.
The MC 350F loves to be revved, which is all possible thanks to the DOHC cylinder head that features large titanium valves and finger followers with a tough Diamond Like Carbon (DLC). The result is minimal friction and optimal performance. The carefully designed combustion chamber produces efficient, high-level power across the entire rev range with the motor also fitted with a multifunctional balancer shaft, which drives the coolant pump and the timing chain.
Performing an important role in delivering the lively performance that makes the MC 350F so much fun to ride, both the cylinder and piston are professionally engineered from high strength aluminum. Guaranteeing outstanding performance and reliability the 88mm bore houses a rigid, forged bridged-box-type piston made by CP.
The right gear, every time. With a low-friction coating on the internal shifting fork, all 5 gear changes on the MC 350F are smooth and purposeful. Light and durable, and featuring motocross specific ratios, the 5-speed transmission itself ensures all power is transferred to the rear wheel, exactly when it’s needed.
Up and down, round and round… life’s tough being a 350F crankshaft. Good job that the spinning heart of the MC 350F motor is designed to offer durability and the best possible performance. Carefully located within the motor it also helps centralize oscillating masses for super easy handling.
The protective housing that keeps all internal components safe and secure! Holding all internal parts in the perfect positions to achieve the ideal center of gravity, the high-pressure casting process ensures strength and thin wall thickness for minimal weight.
Our exhaust systems are key to the power delivery of all GASGAS motocross bikes. Developed to be slim using an innovative 3D process, they comply with FIM sound regulations, look great and most importantly deliver the very best performance. The MC 350F features two-part exhaust systems that are expertly designed to deliver awesome performance at the lowest possible weight. They can also be removed without needing to take out the rear shock! Further innovation allows for a short, compact silencer that keeps sound levels down and looks up.
Allowing riders to keep the MC 350F motor singing all race long, all bikes are fitted with Dampened Diaphragm Steel (DDS) clutch. Featuring a single diaphragm steel pressure plate instead of traditional coil springs the clutch basket is a single-piece CNC machined steel for incredible durability.
