PERFORMANCE MACHINE: Transforming Your Bike From Ordinary To Extraordinary

Enhance your Harley-Davidson’s® performance, handling, and style with top-quality parts from the experts at Performance Machine. This guide explores Performance Machine’s unrivaled selection of wheels, brakes, controls, and other essential upgrades to customize your bike and own the road.


Founded in 1970, Performance Machine manufactures the highest-performing, most durable, and visually stunning motorcycle parts money can buy. The company pioneered the use of billet aluminum in wheels, making them lighter and stronger than cast parts. This obsession with innovative materials and technology transformed the aftermarket industry.

Upgrading key components pays dividends in aesthetics, handling, horsepower, and control. Lighter wheels reduce unsprung weight for quicker acceleration and deceleration. Better brakes improve stopping distances in rain or shine. Extended controls tailor the ergonomics and riding position to your body. And free-flowing intakes unlock hidden horsepower reserves in the engine.
