For decades, the FMF Racing company based in Santa Fe, Southern California, has been successfully designing, producing, and distributing premium-quality, high-performance motorcycle exhaust systems. It was started in 1973 by an avid dirt bike racer Don Emler in his garage in Hawthorne, California. He began modifying his and his friends’ exhaust to make their bikes faster. He called his shop The Flying Machine Factory, hence the name FMF. Don and later his son, Donnie Jr. came up with lots of patented innovations that are now widely used by competitors.
The company’s focus is constantly changing according to technology transformations and trends progression occurring in the motorsport racing scene. By keeping the finger on the pulse and keeping up with the recent developments on the market, FMF Racing achieved one of the leading positions in the motorcycle exhaust technology niche. Today, the red and yellow FMF logo is instantly recognizable all around the world. Bike racing enthusiasts and professional racing teams prefer FMF exhaust system parts for their solid construction and reduced weight thanks to the use of modern aerospace-grade materials.
The company’s patented Resonance Chamber Technology allows for shortening the overall length of the FMF pipe, which results in reduced probability of suffering from crash damage. The center of mass, in this case, can be moved closer to the engine to improve riding balance. FMF racing exhaust systems provide for enormous power gains throughout the whole RPM range. There are models for four-stroke and two-stroke engines. The company offers a huge assortment of pipes, silencers, mufflers, headers, heat shields replacement parts, clamps, springs, tie-downs, brackets, mounting kits, FMF logo stickers, and much more. For almost half a century, the company’s goal remains unchanged – and that is pushing the limits of the most advanced technologies and machinery to build the greatest possible exhausts thus helping customers to get the most from their riding experience.
