Find Engines from FMF for motorcycle

Unleash the true potential of your motorcycle´s engine with FMF Racing, the legendary name in high-performance exhaust systems. For decades, FMF (Flying Machine Factory) has been the undisputed leader in unlocking horsepower, increasing torque, and defining the sound of victory on tracks and trails around the world. When you´re looking to upgrade the very heart of your machine, the engine, an FMF exhaust is the most significant and impactful modification you can make.

At the core of every powerful motorcycle is an engine that can breathe efficiently. FMF has perfected the art and science of engine breathing through their world-renowned exhaust systems. An FMF upgrade is more than just a new part; it´s a fundamental enhancement to your engine´s power delivery, throttle response, and overall character. By optimizing exhaust gas flow, FMF systems allow your engine to expel spent gases faster, making room for a bigger, cleaner air-fuel charge. The result is a direct and noticeable increase in performance that you can feel with every twist of the throttle.

For the four-stroke rider, FMF offers a revolutionary approach to engine tuning with their iconic header designs. The FMF MegaBomb header is a masterclass in engineering, utilizing a unique mid-section chamber to increase exhaust gas flow and scavenging. This translates into massive low-to-mid-range torque gains, perfect for powering out of corners and conquering technical terrain, all while reducing sound output. Pair it with a lightweight PowerCore or Factory 4.1 RCT silencer, crafted from premium aluminum, stainless steel, and titanium, to create a full system that sheds pounds and adds serious, race-proven power. Whether you choose a convenient slip-on muffler for a quick boost or a complete system for maximum engine performance, FMF provides the ultimate 4-stroke solution.

Two-stroke purists know that the expansion chamber is the soul of the engine. FMF´s legacy was built on perfecting the two-stroke pipe. The iconic FMF Fatty pipe is engineered to broaden and smooth out the powerband, delivering more tractable power across the entire RPM range for motocross and all-around performance. For the hardcore enduro and off-road rider, the FMF Gnarly pipe is constructed from heavy-duty 18-gauge steel, designed to deliver a punch of low-end torque and withstand the brutal demands of trail riding. Matched with a TurbineCore 2.1 or PowerCore 2 silencer, you´ll experience that crisp, iconic two-stroke sound and a massive improvement in engine responsiveness.

Proudly designed and handcrafted in the USA, every FMF product is a testament to quality and a passion for riding. This is not just another aftermarket part; it´s a piece of racing heritage, tested and proven in the crucible of professional Motocross, Supercross, and GNCC racing. By choosing FMF for your motorcycle, you are investing in a legacy of performance that will transform your riding experience. Feel the power, hear the sound, and dominate the competition. Upgrade your engine´s performance with an FMF exhaust system from motardinn today
