Model Description


MC 350F 2023

The MC 350F is without a doubt the ultimate modern-day motocrosser.
Giving riders of all abilities the very best of everything, it offers
the perfect balance of dirt-shredding power, lightweight handling, and
superior braking lap after lap. Sounds pretty awesome doesn’t it? Truth
is, it is!
 
BODYWORK
Sleek red bodywork allows for unrestricted movement on the MC 350F for
total control when you’re getting on the gas or hitting the brakes hard.
Complete with a high grip, all-red seat cover, you’ll take to the track
in complete control.
 
AIRBOX
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.
 
HANDLEBAR, GRIPS AND THROTTLE ASSEMBLY
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.
 
FUEL TANK
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.
 
FRAME
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.
 
SUBFRAME
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.
 
FORGED TRIPLE CLAMPS
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. 
 
WP FORKS
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.
 
WP SHOCK
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.
 
SWINGARM
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.
 
MOTOR
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.
 
CYLINDER HEAD AND BALANCER SHAFT
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.
 
CYLINDER AND PISTON
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.
 
TRANSMISSION
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.
 
CRANKSHAFT
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.
 
CRANKCASE
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.
 
EXHAUST SYSTEM
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.
 
DS CLUTCH
Allowing riders to keep the MC 350F motor singing all race long, all bikes are fitted with Diaphragm Steel (DS) clutch. Featuring a single diaphragm steel pressure plate instead of traditional coil springs the clutch basket is a single-piece CNC machined steel component that allows the use of thin steel liners. Light and precise the clutch ensures a smooth and constant action no matter how much abuse it receives!

BRAKES
Fast is fun but slowing down is essential, which is why all GASGAS
motocross bikes are fitted with Brembo calipers and controls. With 260mm
front and 220mm rear disks, braking is easy, inspiring riders to push
harder and ride faster.

BREMBO HYDRAULIC CLUTCH
No need for adjustment and a near maintenance-free operation, but the best thing about the Brembo hydraulic clutch is that it delivers a perfectly smooth action time and time again. With lever free-play automatically adjusted, the biting point and function of the clutch remain constant no matter if it’s hot or cold.

INTEGRATED COOLING SYSTEM AND RADIATORS
Keeping our bikes slim means better handling, which is why the GASGAS motocross range features cooling systems that are integrated into the frames. Also allowing for improved cooling due to eliminating the need for additional hoses, together with the high-strength, lightweight radiators the complete system ensures, well, our bike stay super cool no matter how tough the conditions!

WHEELS
Built to take a beating, our wheels are ready to play rough. No matter how heavy the landing or how rough the track, the silver, high-strength rims, CNC machined hubs and lightweight spokes deliver maximum strength for complete peace of mind.

ENGINE MANAGEMENT SYSTEM
Super small but the best there is when it comes to processing engine
data. Used to control all parameters linked to the fuel-injections
system, the Keihin EMS unit also features a gear sensor that allows a
tailored power delivery for each gear.

44MM THROTTLE BODY
The MC 350F uses a 44mm Keihin throttle body with an injector 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 system ensures an immediate throttle response.

ELECTRIC START AND LI-ION BATTERY
No need to kick, kick, kick! All GASGAS 4-strokes motocross bikes are fitted with an electric starter as standard. Saving time at the start of a day when a motor’s cold, or near the end of a race when the motor’s hot, with the simple press of a button the MC 350F fires into life. Using a lightweight Li-Ion 2.0 Ah battery together with a robust starter motor from Mitsuba and a reliable starter drive guarantees reliable starting. Always.
