Performance Machine has been in business since 1970. They started cranking out aftermarket front ends and brake systems for Harley-Davidson's. Not content with resting on their laurels, mag wheels were added to the lineup in 1975. In 1982, PM started making brake calipers that were carefully machined from aerospace-grade solid aluminum bars. PM expanded into racing brake systems, and then dominated the custom chopper craze that gripped the United States for over a decade. They conjured up some of the most radical wheels seen on a motorcycle up until that point. Still one of the most serious contenders in terms of braking systems for Harley Davidson Motorcycles, Performance Machine produces a wide variety of superior calipers and quality aftermarket products for both stock and custom applications. Add some performance to your machine.
