Accessory calipers from Performance Machine

Performance Machine calipers are superior to the original Harley-Davidson ones until the early 2000s. They were originally invented for racing motorcycles. But better braking performance, sophisticated design and fixed caliper technology with double-acting pistons were the deciding factors for many riders to install PM's calipers on Harley-Davidson street bikes as well. With the introduction of solid, CNC machined calipers in 1982, Performance Machine achieved the status as an industry leader that continues to distinguish them today. Of course, it didn´t take long before they were copied. PM's design suddenly found itself everywhere, with some of these "milling shops" just bothering to swap out the logo. And of course - because of the saved development costs - the copies were also available much cheaper. But because W&W has carried PM's calipers since the early days of 1979, and because W&W has always emphasized quality, experience, and extensive testing, these copies have never been available at W&W Cycles. Nowadays most of these copies have disappeared from the market, but Performance Machine calipers are still available at W&W.

W&W's selection of PM calipers

Performance Machine is characterized by a modular system that combines a single-digit number of basic designs with model-specific holders. In addition, there are calipers for front forks from 1984 onward whose mounting tabs can be bolted directly to the fork legs. The mechanic with a lot of experience can of course opt for a single caliper and laser-cut his own brackets from an aluminum plate.
