About FMF

One man, in the name of power.

In 1973 Don Emler created FMF out of a desire to go faster. For nearly fifty years FMF has been leading in the pursuit of precision, power and speed.

1973was about revolutionary firsts. Zeppelin, Floyd and the Stones were setting the world ablaze. We tasted our first Lite beer, rode our first Jet Ski, and Don Emler lit the torch sparking one of the most influential brands in motorcycle history. In his mind he isALWAYS RACING.

Like most pioneering inventors, Big D built his performance exhausts with a sense of purpose. From day onealways striving for perfection. FMF isALWAYS INNOVATING.

45 years later the song remains the same. FMF still engineers and builds everything by hand, from the ground up in the USA. As long as you dream of flying higher and going faster, we will continue to innovate and build things the right wayTHE AMERICAN WAY.
